It is a tool for producing beautiful manu\SpecialChar softhyphen scripts, publishable books, business letters and proposals, and even poetry. It is unlike most other \begin_inset Quotes eld \end_inset word processors \begin_inset Quotes erd \end_inset in the sense that it uses the paradigm of a markup language as its core editing style. That means that when you type a section header, you mark it as a \begin_inset Quotes eld \end_inset Section \begin_inset Quotes erd \end_inset , not as \begin_inset Quotes eld \end_inset Bold, 17 \begin_inset space \thinspace{} \end_inset pt type, left justified, 5 \begin_inset space \thinspace{} \end_inset mm space below \begin_inset Quotes erd \end_inset . \SpecialChar LyX takes care of the typesetting for you; so you deal only with concepts, not with mechanics. \end_layout \begin_layout Standard This philosophy is explained in greater detail in the \emph on Introduction \emph default manual. If you haven't read it yet, you need to. Yes, we mean now. \end_layout \begin_layout Standard The \emph on Introduction \emph default manual describes several things in addition to \SpecialChar LyX 's philosophy: most importantly, the format of all of the manuals. If you don't read it, you will have a bear of a time navigating this manual. You might also be better served looking in one of the other manuals instead of this one. The \emph on Introduction \emph default manual describes that, too. \end_layout \begin_layout Section How \SpecialChar LyX Looks \end_layout \begin_layout Standard Like most applications, \SpecialChar LyX has the familiar menu bar across the top of its window. Below it is a toolbar with a pulldown box and various buttons. There is, of course, a vertical scrollbar and a main work area for editing documents. \end_layout \begin_layout Standard Note that there is no horizontal scrollbar. This is not a bug or an oversight, but intentional. When you read a book, you expect the end of a line to wrap around to the next line. Text overflows onto new pages in a vertical fashion, hence the need for only a vertical scrollbar. There are three cases where you might want a horizontal scrollbar. The first case is large images. To avoid them being displayed larger than your screen, left click on the image and use the option \family sans Scale on Screen \family default in the tab \family sans \SpecialChar LaTeX and \SpecialChar LyX options \family default . The second and third cases are tables and equations which are wider than the \SpecialChar LyX window. You can use the arrow keys to scroll horizontally through the table, but this doesn't work for equations yet. \end_layout \begin_layout Standard For a brief description of all \SpecialChar LyX menus and toolbar buttons, have a look at Appendix \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "chap:The-User-Interface" \end_inset . \end_layout \begin_layout Section HELP \end_layout \begin_layout Standard The help system consists of the \SpecialChar LyX manuals. You can read all of the manuals from inside \SpecialChar LyX . Just select the manual you want to read from the \family sans Help \family default menu. \end_layout \begin_layout Section Basic \SpecialChar LyX Setup \begin_inset CommandInset label LatexCommand label name "sec:Basic-LyX-Setup" \end_inset \end_layout \begin_layout Standard Almost all features of \SpecialChar LyX can be configured via the menu \family sans Tools\SpecialChar menuseparator Preferences \family default . \begin_inset Index idx status collapsed \begin_layout Plain Layout Preferences \end_layout \end_inset \SpecialChar LyX is able to inspect your system to see what programs, \SpecialChar LaTeX document classes and \SpecialChar LaTeX packages are available. It uses this knowledge to give reasonable defaults for the preferences settings. Although this configuration has already been done when \SpecialChar LyX was installed on your system, you might have some items that you installed locally, e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset new \SpecialChar LaTeX classes, and which are not seen by \SpecialChar LyX . To force \SpecialChar LyX to re-inspect your system, you should use \family sans Tools\SpecialChar menuseparator Reconfigure \family default . \begin_inset Index idx status collapsed \begin_layout Plain Layout Reconfiguration of \SpecialChar LyX \end_layout \end_inset You should then restart \SpecialChar LyX to ensure that the changes are taken into account. \end_layout \begin_layout Section \SpecialChar LaTeX Setup \begin_inset CommandInset label LatexCommand label name "sec:LaTeX-Setup" \end_inset \end_layout \begin_layout Standard You can edit documents in \SpecialChar LyX without having \SpecialChar LaTeX installed, but you will not be able to create PDFs or print your documents unless you do have it installed. However, some \SpecialChar LyX documents use DocBook as the “backend” that can produce PDFs and the like, and every \SpecialChar LyX document can always be output as plain text or as XHTML. \end_layout \begin_layout Standard Some document classes may depend upon specific \SpecialChar LaTeX or DocBook classes or packages. Such document classes can be used even if you do not have the required files installed, but you will not be able to produce certain kinds of output. \end_layout \begin_layout Standard The \SpecialChar LaTeX packages that \SpecialChar LyX has found on your system are listed in a file you can view from the menu \family sans Help\SpecialChar menuseparator LaTeX \begin_inset space ~ \end_inset Configuration \family default . If you are missing packages you need, then you must install them and then reconfigure \SpecialChar LyX (menu \family sans Tools\SpecialChar menuseparator Reconfigure \family default ). \begin_inset Index idx status collapsed \begin_layout Plain Layout Reconfiguration of \SpecialChar LyX \end_layout \end_inset See section \emph on Installing new \SpecialChar LaTeX files \emph default of the \emph on Customization \emph default manual for more information on installing additional \SpecialChar LaTeX packages. \end_layout \begin_layout Chapter How to work with \SpecialChar LyX \end_layout \begin_layout Section Basic File Operations \begin_inset Index idx status collapsed \begin_layout Plain Layout File Operations \end_layout \end_inset \end_layout \begin_layout Standard Under the \family sans File \family default menu and in the standard toolbar are basic operations for any word processor in addition to some more advanced operations: \end_layout \begin_layout Itemize \family sans New, \family default \begin_inset Info type "shortcut" arg "buffer-new" \end_inset or \family sans \begin_inset Info type "icon" arg "buffer-new" \end_inset \end_layout \begin_layout Itemize \family sans New \begin_inset space ~ \end_inset from \begin_inset space ~ \end_inset Template, \family default \begin_inset Info type "shortcut" arg "buffer-new-template" \end_inset \end_layout \begin_layout Itemize \family sans Open, \family default \begin_inset Info type "shortcut" arg "file-open" \end_inset or \family sans \begin_inset Info type "icon" arg "file-open" \end_inset \end_layout \begin_layout Itemize \family sans Open \begin_inset space ~ \end_inset Recent \end_layout \begin_layout Itemize \family sans Close, \family default \begin_inset Info type "shortcut" arg "view-close" \end_inset \end_layout \begin_layout Itemize \family sans Save, \family default \begin_inset Info type "shortcut" arg "buffer-write" \end_inset or \family sans \begin_inset Info type "icon" arg "buffer-write" \end_inset \end_layout \begin_layout Itemize \family sans Save \begin_inset space ~ \end_inset As, \family default \begin_inset Info type "shortcut" arg "buffer-write-as" \end_inset \end_layout \begin_layout Itemize \family sans Revert \begin_inset space ~ \end_inset to \begin_inset space ~ \end_inset saved \end_layout \begin_layout Itemize \family sans Exit, \family default \begin_inset Info type "shortcut" arg "lyx-quit" \end_inset \end_layout \begin_layout Standard They all do pretty much the same thing as in other word processors, with a few minor differences. The \family sans File\SpecialChar menuseparator New \begin_inset space ~ \end_inset from \begin_inset space ~ \end_inset Template \family default command lists the available templates. Selecting a template will automatically set certain layout features for the document, features you would otherwise need to change manually. They can be of use for certain classes, especially those for writing letters (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Document-Classes" \end_inset ). \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default There is no \begin_inset Quotes eld \end_inset default file \begin_inset Quotes erd \end_inset or document named \begin_inset Quotes eld \end_inset Untitled \begin_inset Quotes erd \end_inset or \begin_inset Quotes eld \end_inset scratch. \begin_inset Quotes erd \end_inset Unless you tell \SpecialChar LyX to open a file or create a new one, that big, blank space is just that — a big, blank space. \end_layout \end_inset \end_layout \begin_layout Standard \family sans Revert \begin_inset space ~ \end_inset to \begin_inset space ~ \end_inset saved \family default and \family sans Version \begin_inset space ~ \end_inset Control \family default are useful if more people work on the same document at the same time. \begin_inset Foot status collapsed \begin_layout Plain Layout If you plan to do this, you should check out the Version Control feature in \SpecialChar LyX also. Read Additional Features\SpecialChar endofsentence \end_layout \end_inset \family sans Revert \begin_inset space ~ \end_inset to \begin_inset space ~ \end_inset saved \family default will reload the document from disk. You can of course also use it if you regret that you changed a document and want to restore it to the last save. With \family sans Version \begin_inset space ~ \end_inset Control \family default you can register the changes you made to a document so that others can identify them as your changes. \end_layout \begin_layout Section Basic Editing Features \begin_inset Index idx status collapsed \begin_layout Plain Layout Editing \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Basic-Editing-Features" \end_inset \end_layout \begin_layout Standard Like most modern word processors, \SpecialChar LyX can perform cut and paste operations on blocks of text, can move by character, word, or page of text, and can delete whole words as well as individual characters. The next four sections cover the basic \SpecialChar LyX editing features and how to access them. We will start with cut and paste. \end_layout \begin_layout Standard As you might expect, the \family sans Edit \family default menu and the standard toolbar has the cut and paste commands, along with various other editing features. Some of these are special and covered in later sections. The basic ones are: \end_layout \begin_layout Itemize \family sans Cut \family default \begin_inset Index idx status collapsed \begin_layout Plain Layout Cut \end_layout \end_inset \family sans , \family default \begin_inset Info type "shortcut" arg "cut" \end_inset or \family sans \family default \begin_inset Info type "icon" arg "cut" \end_inset \end_layout \begin_layout Itemize \family sans Copy \family default \begin_inset Index idx status collapsed \begin_layout Plain Layout Copy \end_layout \end_inset \family sans , \family default \begin_inset Info type "shortcut" arg "copy" \end_inset or \family sans \family default \begin_inset Info type "icon" arg "copy" \end_inset \end_layout \begin_layout Itemize \family sans Paste \family default \begin_inset Index idx status collapsed \begin_layout Plain Layout Paste \end_layout \end_inset , \begin_inset Info type "shortcut" arg "paste" \end_inset or \family sans \family default \begin_inset Info type "icon" arg "paste" \end_inset \end_layout \begin_layout Itemize \family sans Paste \begin_inset space ~ \end_inset Recent \end_layout \begin_layout Itemize \family sans Paste \begin_inset space ~ \end_inset Special \end_layout \begin_layout Itemize \family sans Find \begin_inset space ~ \end_inset & \begin_inset space ~ \end_inset Replace \family default \begin_inset Index idx status collapsed \begin_layout Plain Layout \family sans Find \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout \family sans Replace \end_layout \end_inset \family sans , \family default \begin_inset Info type "shortcut" arg "dialog-show findreplaceadv" \end_inset or \family sans \family default \begin_inset Info type "icon" arg "dialog-show findreplace" \end_inset \end_layout \begin_layout Standard The first three are self-explanatory. You can also copy text between \SpecialChar LyX and other programs by \family sans Cut \family default , \family sans Copy \family default and \family sans Paste \family default . \family sans Cut \family default and \family sans Copy \family default put text in two versions into the clipboard (formatted and unformatted), so that other programs can choose the most suitable form. \family sans Paste \family default supports formatted and unformatted text as well, and additionally graphics. It tries to interpret the clipboard contents in an intelligent way. For example if the clipboard contains text in the format of comma separated values (CSV) and the cursor is inside a table, the text will be pasted into individual cells. The submenu of \family sans Paste \begin_inset space ~ \end_inset Recent \family default shows you a list with the last strings you have pasted. You can insert one at the current cursor position by clicking on a list entry. \end_layout \begin_layout Standard The submenu \family sans Paste \begin_inset space ~ \end_inset Special \family default contains optional items for specific formats, depending on the clipboard contents. These include HTML, \SpecialChar LaTeX , Linkback \begin_inset space ~ \end_inset PDF \begin_inset Foot status collapsed \begin_layout Plain Layout OS X only \end_layout \end_inset , PDF, PNG, JPEG and EMF. These menu items are useful if the clipboard contains the same contents in different formats, and you want to select one format explicitly. (E. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset some programs put an image into the clipboard as graphics and as a short text which is often meaningless.) The menu item \family sans Paste \begin_inset space ~ \end_inset Special\SpecialChar menuseparator Plain \begin_inset space ~ \end_inset Text, \begin_inset space \thinspace{} \end_inset Join \begin_inset space ~ \end_inset Lines \family default is equivalent to \family sans Paste \family default , with the only difference that it acts on text only. It will insert the text in the clipboard so that the whole text is inserted as one paragraph. A new paragraph is only started when there is a blank line in the text. Without \family sans Join \begin_inset space ~ \end_inset Lines \family default the text is inserted as paragraphs where the line breaks of the text will start a new paragraph. This is for example useful to copy contents of tables from webpages to a table in \SpecialChar LyX . The items \family sans Paste \begin_inset space ~ \end_inset Special\SpecialChar menuseparator Selection, \begin_inset space \thinspace{} \end_inset Join \begin_inset space ~ \end_inset Lines \family default and \family sans Paste \begin_inset space ~ \end_inset Special\SpecialChar menuseparator Selection \family default paste from the primary selection. This is normally the currently selected text. \end_layout \begin_layout Standard The \family sans Edit\SpecialChar menuseparator Find \begin_inset space ~ \end_inset & \begin_inset space ~ \end_inset Replace \family default item opens the \family sans Find \begin_inset space ~ \end_inset and \begin_inset space ~ \end_inset Replace \family default dialog. Once you have found a word or expression, \SpecialChar LyX selects it. Hitting the \family sans Replace \family default button replaces the selected text with the contents of the \family sans Replace \begin_inset space ~ \end_inset with \family default field. You can click the \family sans Find \begin_inset space ~ \end_inset Next \family default button to skip the current word. Hit \family sans Replace \begin_inset space ~ \end_inset All \family default to replace all occurrences of the text in the document automatically. The \family sans Case \begin_inset space ~ \end_inset sensitive \family default option can be used if you want the search to consider the case of the search word. If the toggle is set, searching for \begin_inset Quotes eld \end_inset \family typewriter Test \family default \begin_inset Quotes erd \end_inset will not match the word \begin_inset Quotes eld \end_inset \family typewriter test \family default \begin_inset Quotes erd \end_inset . The \family sans Match whole words only \family default option can be used to force \SpecialChar LyX to only find complete words, e. \begin_inset space \thinspace{} \end_inset g., searching for \begin_inset Quotes eld \end_inset \family typewriter star \family default \begin_inset Quotes erd \end_inset will not match \begin_inset Quotes eld \end_inset \family typewriter starlet \family default \begin_inset Quotes erd \end_inset . \SpecialChar LyX offers also an advanced \family sans Find \begin_inset space ~ \end_inset & \begin_inset space ~ \end_inset Replace \family default feature that is described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Advanced-Find-and" \end_inset . \end_layout \begin_layout Standard Things like notes, floats, etc. \begin_inset space \space{} \end_inset (the so called \begin_inset Quotes eld \end_inset insets \begin_inset Quotes erd \end_inset ) can be dissolved. This means that the inset is deleted and its content is left as normal text. Dissolving an inset is done by setting the cursor to the beginning of an inset and pressing \family sans Backspace \family default or by setting the cursor to the end and pressing \family sans Delete \family default . \end_layout \begin_layout Standard Using the shortcut \begin_inset Info type "shortcuts" arg "inset-select-all" \end_inset while the cursor is in normal text selects the whole document. When the cursor is inside an inset \begin_inset Info type "shortcuts" arg "inset-select-all" \end_inset selects the content of the inset. Using \begin_inset Info type "shortcuts" arg "inset-select-all" \end_inset consecutively will increase the selection to the whole inset and then to the whole document. The shortcut \begin_inset Info type "shortcuts" arg "command-sequence buffer-begin ; buffer-end-select" \end_inset selects the whole document in every case and puts the cursor to the end of the document. \end_layout \begin_layout Section Undo and Redo \begin_inset Index idx status collapsed \begin_layout Plain Layout Redo \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Undo \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Undo-and-Redo" \end_inset \end_layout \begin_layout Standard If you make a mistake, you can easily recover from it. \SpecialChar LyX has a large-capacity undo/redo buffer. Select \family sans Edit\SpecialChar menuseparator Undo \family default or the toolbar button \begin_inset Info type "icon" arg "undo" \end_inset to undo some mistake. If you accidentally undo too much, use \family sans Edit\SpecialChar menuseparator Redo \family default or the toolbar button \begin_inset Info type "icon" arg "redo" \end_inset to \begin_inset Quotes eld \end_inset undo the undo. \begin_inset Quotes erd \end_inset The undo mechanism is currently limited to 100 \begin_inset space \thinspace{} \end_inset steps to minimize memory overhead. \end_layout \begin_layout Standard Note that if you revert back all changes to arrive at the document as it was last saved, the \begin_inset Quotes eld \end_inset changed \begin_inset Quotes erd \end_inset status of the document is unfortunately not reset. This is a consequence of the 100 \begin_inset space \thinspace{} \end_inset step undo limit mentioned above. \end_layout \begin_layout Standard \family sans Undo \family default and \family sans Redo \family default work on almost everything in \SpecialChar LyX . But they will not undo or redo text character by character, but by blocks of text. \end_layout \begin_layout Section Mouse Operations \begin_inset Index idx status collapsed \begin_layout Plain Layout Mouse Operations \end_layout \end_inset \end_layout \begin_layout Standard These are the most basic mouse operations. \end_layout \begin_layout Enumerate Motion \end_layout \begin_deeper \begin_layout Itemize Click the \emph on left mouse button \emph default once anywhere in the edit window. The cursor moves to the text under the mouse. \end_layout \end_deeper \begin_layout Enumerate Selecting Text \end_layout \begin_deeper \begin_layout Itemize Hold down the \emph on left mouse button \emph default and drag the mouse. \SpecialChar LyX marks the text between the old and new mouse positions. Use \family sans Edit\SpecialChar menuseparator Copy \family default to create a copy of the text in \SpecialChar LyX 's buffer (and the clipboard). \end_layout \begin_layout Itemize Re-position the cursor and then paste the text back into \SpecialChar LyX using \family sans Edit\SpecialChar menuseparator Paste \family default . \end_layout \end_deeper \begin_layout Enumerate Insets (Footnotes, Notes, Floats, etc.) \end_layout \begin_deeper \begin_layout Standard Right-click on them to set their properties. Also check the appropriate section of this manual for more details. \end_layout \end_deeper \begin_layout Section Navigating \begin_inset CommandInset label LatexCommand label name "sec:Navigating" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Navigating \end_layout \end_inset \end_layout \begin_layout Standard \SpecialChar LyX offers you several ways to navigate in documents: \end_layout \begin_layout Itemize The \family sans Navigate \family default menu lists all sections of the document as submenu entries that you can click to jump to the corresponding document part. \end_layout \begin_layout Itemize The “Outline”, which is accessed either by the menu \family sans View\SpecialChar menuseparator Outline \begin_inset space ~ \end_inset Pane \family default or by the toolbar button \begin_inset Info type "icon" arg "dialog-toggle toc" \end_inset . \end_layout \begin_layout Itemize You can set bookmarks in your document under \family sans Navigate\SpecialChar menuseparator Bookmarks \family default and use the same menu to return to them. Note that bookmarks are saved between sessions. \end_layout \begin_layout Standard The toolbar button \begin_inset Info type "icon" arg "bookmark-goto 0" \end_inset (also \family sans Navigate\SpecialChar menuseparator Bookmarks\SpecialChar menuseparator Navigate \begin_inset space ~ \end_inset Back \family default ) jumps to the position in the document where you recently changed something. This is useful when you have a large document and have navigated or scrolled to another document part to look for something, and want to go back to your last editing position. \end_layout \begin_layout Standard By pressing the \family sans F5 \family default key the cursor will be vertically centered in \SpecialChar LyX 's main window. \end_layout \begin_layout Subsection The Outliner \begin_inset CommandInset label LatexCommand label name "subsec:The-Outliner" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Navigating ! Outline \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Outline \end_layout \end_inset \end_layout \begin_layout Standard In the pull-down box at the top of the outline window, you can choose between several different lists, including other TOC-like objects, such as lists of tables and figures, but also lists of footnotes, or labels and cross-referen ces (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Cross-References" \end_inset ), or notes, or citations (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Bibliography" \end_inset ). Clicking on any of these will take you to the corresponding object in your document. \end_layout \begin_layout Standard Right-clicking on elements in the Outline opens in many cases a context menu that will allow for direct modification of those elements. For example, with citations, the context menu allows you to open the citation dialog and to modify the citation. \end_layout \begin_layout Standard The \family sans Filter \family default field at the top allows you to restrict which entries appear in the outline. For example, if you are displaying the list of \emph on Labels and References \emph default and wish to see only references to subsections, you can enter the text \begin_inset Quotes eld \end_inset sub \begin_inset Quotes erd \end_inset in the filter, and only entries containing that text will be displayed. \end_layout \begin_layout Standard At the bottom of the outline are several buttons and the like that allow you further to control the display. The \family sans Sort \family default option sorts the current list alphabetically. Otherwise, the elements appear in the order in which they occur in the document. The \family sans Keep \family default option keeps it in the current view state. Keeping means that when you have, for example, the subsections of sections \begin_inset space ~ \end_inset 2 and 4 displayed and click on section \begin_inset space ~ \end_inset 3, the subsections of sections \begin_inset space ~ \end_inset 2 and 4 will still be displayed. Without the \family sans Keep \family default option they will be hidden to highlight the clicked section \begin_inset space ~ \end_inset 3. Finally, the slider at the left can be used to open the Outline to a given \begin_inset Quotes eld \end_inset depth \begin_inset Quotes erd \end_inset . It is best just to experiment with it to see how it works. \end_layout \begin_layout Standard The \begin_inset Info type "icon" arg "reload" \end_inset button refreshes the TOC (though this should not usually be necessary). Next to it are buttons that allow you to change the position of sections in your document. The \begin_inset Info type "icon" arg "outline-down" \end_inset and \begin_inset Info type "icon" arg "outline-up" \end_inset buttons move sections up and down in the document. So, for example, you can move section \begin_inset space ~ \end_inset 2.5 before section \begin_inset space ~ \end_inset 2.4 or after section \begin_inset space ~ \end_inset 2.6. \SpecialChar LyX will then automatically renumber the sections to the new order. With the buttons \begin_inset Info type "icon" arg "outline-out" \end_inset and \begin_inset Info type "icon" arg "outline-in" \end_inset (or the corresponding key bindings \family sans Tab \family default and \family sans Shift-Tab \family default ) you can change the level of sections. So you can for example make section \begin_inset space ~ \end_inset 2.5 chapter \begin_inset space ~ \end_inset 3 or subsection \begin_inset space ~ \end_inset 2.4.1. \end_layout \begin_layout Standard By right-clicking on a section in the outliner you can select the whole section to copy, cut or delete it. \end_layout \begin_layout Subsection Horizontal Scrolling \begin_inset Index idx status collapsed \begin_layout Plain Layout Navigating ! Horizontal Scrolling \end_layout \end_inset \end_layout \begin_layout Standard \SpecialChar LyX does not have a horizontal scrollbar because the standard output page formats like e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset ISO \begin_inset space ~ \end_inset A4 are less wide than PC or laptop screens. Therefore you will get troubles in the output of your document if document parts exceed the width of the \SpecialChar LyX main screen. \end_layout \begin_layout Standard There are of course exceptions where horizontal scrolling is necessary. For example \end_layout \begin_layout Itemize \SpecialChar LyX is used on a small tablet computer \end_layout \begin_layout Itemize Wide tables that are rotated 90° to fit a whole page \begin_inset Foot status collapsed \begin_layout Plain Layout See section \emph on Rotated Floats \emph default of the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual. \end_layout \end_inset \end_layout \begin_layout Itemize Math constructs with long command names \end_layout \begin_layout Standard For these cases \SpecialChar LyX has an mechanism that scrolls automatically when the cursor is moved. As example shrink the \SpecialChar LyX windows so that table \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "tab:Horizontal-scrollong-test" \end_inset is wider. You will now see a dotted red line at the right or the left side of the table. Put the cursor into the table and move it with the Tab or the arrow keys to see the horizontal scrolling of the table. \end_layout \begin_layout Standard \begin_inset Float table placement h wide false sideways false status open \begin_layout Plain Layout \begin_inset Caption Standard \begin_layout Plain Layout \begin_inset CommandInset label LatexCommand label name "tab:Horizontal-scrollong-test" \end_inset Horizontal scrolling test. \end_layout \end_inset \end_layout \begin_layout Plain Layout \align center \begin_inset Tabular \begin_inset Text \begin_layout Plain Layout a \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout b \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout c \end_layout \end_inset \end_inset \end_layout \end_inset \end_layout \begin_layout Section Input/Word Completion \begin_inset CommandInset label LatexCommand label name "sec:Input-Completion" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Input completion \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Word completion|see \begin_inset ERT status collapsed \begin_layout Plain Layout { \end_layout \end_inset Input completion \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard \SpecialChar LyX provides completion of words by scanning all documents that are currently opened. Every word that appears in these documents is added to a database that is used to propose completions. \end_layout \begin_layout Standard Input completion can be activated in the \SpecialChar LyX preferences (menu \family sans Tools\SpecialChar menuseparator Preferences \family default ) in the section \family sans Editing\SpecialChar menuseparator Input Completion \family default . With the option \family sans Automatic \begin_inset space ~ \end_inset inline \begin_inset space ~ \end_inset completion \family default the proposed completion is shown directly after the cursor. With the option \family sans Automatic \begin_inset space ~ \end_inset popup \family default the completions are always shown in a popup. The cursor completion indicator can be turned off by deselecting the option \family sans Cursor \begin_inset space ~ \end_inset indicator \family default . With the general options you can define the delay time for the inline and popup completion, you can set the minimal number of characters a word must have that it will be taken into account for a completion and you can choose if long completions should be abbreviated. \end_layout \begin_layout Standard \SpecialChar LyX displays a small triangle after the cursor as an indicator that there are completions available. Press the \family sans Tab \family default key to accept a proposed completion. If several completions are possible, a popup is opened showing them. You can select a completion in the popup using the mouse or the arrow keys, and accept the chosen completion by pressing \family sans Return \family default . \end_layout \begin_layout Standard The completion options for math in the preferences do the same as the correspond ing options for text. The special math option \family sans Autocorrection \family default enables characters to be composed. If, for example, you want to insert the character \begin_inset Formula $\Rightarrow$ \end_inset , you can then input the characters \begin_inset Quotes eld \end_inset \series bold => \series default \begin_inset Quotes erd \end_inset to a formula to get it. So this is a quick alternative to the insertion of commands or the use of the math toolbar. A list with supported character combinations can be found in the file \family typewriter autocorrect \family default that is in \SpecialChar LyX 's installation folder. Math autocorrection can at any time be turned on by pressing the exclamation mark key “!”. Pressing \family sans Space \family default turns it off. \end_layout \begin_layout Section Basic Key Bindings \begin_inset Index idx status collapsed \begin_layout Plain Layout Key Bindings \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Bindings|see \begin_inset ERT status collapsed \begin_layout Plain Layout { \end_layout \end_inset Key Bindings \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Shortcuts|see \begin_inset ERT status collapsed \begin_layout Plain Layout { \end_layout \end_inset Key Bindings \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard There are at least two different primary binding maps: \family typewriter cua \family default and \family typewriter emacs \family default . \SpecialChar LyX 's default is \family typewriter cua \family default , which can be changed in the \SpecialChar LyX preferences under \family sans Editing\SpecialChar menuseparator Shortcuts \family default .

The \SpecialChar LyX menus also list the defined key bindings. The notation for the key bindings is very similar to the notation used in this documentation, so you should not have any problems understanding it. However, notice that Shift-modifiers are explicitly mentioned, so \begin_inset Quotes eld \end_inset \family sans Alt+P Shift+A \family default \begin_inset Quotes erd \end_inset means \family sans Alt+P \family default followed by a capital \family sans A \family default . \end_layout \begin_layout Chapter \SpecialChar LyX Basics \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LyX !

Types \end_layout \end_inset \end_layout \begin_layout Subsection Introduction \end_layout \begin_layout Standard Before you do anything else, before you ever start writing a document, you need to decide what type of document you want to edit. Different types of documents use different types of spacing, headings, numbering schemes, and so on. Additionally, different documents use different paragraph environments, and format the title of your document differently. \end_layout \begin_layout Standard A \emph on document class \emph default describes a group of properties common to a particular set of documents. By setting the document class, you automatically select these properties, making it easier to create the type of document you want. If you don't choose a document class, \SpecialChar LyX picks one for you by default. So it is up to you to change the class of your document. \end_layout \begin_layout Subsection Document Classes \begin_inset Index idx status collapsed \begin_layout Plain Layout Document !

Select the class you want to use, and make any fine tunings of the options you may need. \end_layout \begin_layout Subsubsection Overview \end_layout \begin_layout Standard There are four standard document classes in \SpecialChar LyX . They are: \end_layout \begin_layout Description Article for basic articles \end_layout \begin_layout Description Report for basic reports \end_layout \begin_layout Description Book for writing a book \end_layout \begin_layout Description Letter for US-style letters \end_layout \begin_layout Standard There are also some non-standard classes, which \SpecialChar LyX only uses if you have installed the corresponding \SpecialChar LaTeX class files, though most \SpecialChar LaTeX distributions will include many of these. Here are some of the classes. The full list with detailed explanations can be found in chapter \emph on Special Document Classes \emph default in the \emph on Additional Features \emph default manual: \end_layout \begin_layout Description A&A Journal articles in the style and format used in Astronomy & Astrophysics \end_layout \begin_layout Description ACS For submissions to the journals published by the American Chemistry Society \end_layout \begin_layout Description AGU For submissions to the journals published by the American Geophysical Union \end_layout \begin_layout Description AMS Layouts for articles and books in the style and format used by the American Mathematical Society (AMS). There are three article layouts available. The standard one uses a typical numbering scheme for theorems etc., that prepends the section number to the number of the result. All result-type statements (propositions, corollaries, and so on) are sequenced together, but definitions, examples, and the like have their own sequence. The \begin_inset Quotes eld \end_inset sequential numbering \begin_inset Quotes erd \end_inset scheme does not place the section number with each result, but numbers them throughout the article in a single sequence. Each type of result gets its own sequence. There is also a layout that dispenses with numbering of statements altogether. \end_layout \begin_layout Description Beamer Layout for presentations \end_layout \begin_layout Description Broadway Layout for writing plays. It is not an existing \SpecialChar LaTeX document class, but a new one that is distributed with \SpecialChar LyX . \end_layout \begin_layout Description Chess Layout to write about chess games \end_layout \begin_layout Description Curriculum \begin_inset space ~ \end_inset vitae classes to create curriculum vitae \end_layout \begin_layout Description Elsarticle Layout for journals of the Elsevier publishing group \end_layout \begin_layout Description Foils Used to make transparencies \end_layout \begin_layout Description Hollywood Used to type spec scripts for the US film industry. It is not an existing \SpecialChar LaTeX document class, but a new one that is distributed with \SpecialChar LyX . \end_layout \begin_layout Description IEEEtran Layout for the journals published by the Institute of Electrical and Electronics Engineers (IEEE) \end_layout \begin_layout Description IOP Layout for journals of the Institute of Physics publishing group \end_layout \begin_layout Description Kluwer Layout for journals of the Kluwer publishing group \end_layout \begin_layout Description KOMA-Script a replacement for the standard classes, offers many useful features like caption formatting, automatic print space calculation etc. (Is used by this document.) \end_layout \begin_layout Description Memoir another replacement for the standard classes \end_layout \begin_layout Description Powerdot Layout for presentations \end_layout \begin_layout Description REV \family sans TeX \family default is used to write articles for the publications of the American Physical Society (APS), American Institute of Physics (AIP), and Optical Society of America (OSA). This class is not completely compatible with all \SpecialChar LyX features. \end_layout \begin_layout Description Slides Used to make transparencies \end_layout \begin_layout Description SPIE \begin_inset space ~ \end_inset Proceedings Layout for the journals published by The International Society for Optical Engineering (SPIE) \end_layout \begin_layout Description Springer Layouts for journals of the Springer publishing group \end_layout \begin_layout Standard We will not go into detail about how to use these different document classes here. You can find details about the non-standard classes in chapter \emph on Special Document Classes \emph default of the \emph on Additional Features \emph default manual. Here, we will settle for a list of some of the common properties of all of the document classes. \end_layout \begin_layout Subsubsection Availability \end_layout \begin_layout Standard You will probably find that many of the document classes listed under \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Document Class \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Settings \end_layout \end_inset \family default are marked as \begin_inset Quotes eld \end_inset Unavailable \begin_inset Quotes erd \end_inset . If you open a document that uses such a class, you will receive a warning saying that there are files that are required to produce output that are not installed. So it may seem that something is wrong. \end_layout \begin_layout Standard Nothing is wrong. \SpecialChar LyX includes many more document classes than you will ever need to use, and some of them, like \family sans IOP \family default , are highly specialized. \SpecialChar LyX tries to support as many different types of documents as possible, and it includes almost one hundred different layout files, with a growing number. No \SpecialChar LaTeX distribution will install by default all files that might be needed by some document class. There are just too many of them. That is why some of the document classes are unavailable. \end_layout \begin_layout Standard If there is a document class you would like to use that is marked as \begin_inset Quotes eld \end_inset Unavailable \begin_inset Quotes erd \end_inset , you just need to install the appropriate package files. The easiest way to find out which files you need to install is to use that document class for a new file. \SpecialChar LyX will display a dialog that will list the missing files. See section \emph on Installing new \SpecialChar LaTeX files \emph default in of the \emph on Customization \emph default manual for information on how to install them. \begin_inset VSpace medskip \end_inset \end_layout \begin_layout Standard Although \SpecialChar LyX provides support for many different sorts of documents, it does not include support for every document class people might want to use. For example, many universities provide \SpecialChar LaTeX class files to be used for dissertation s submitted to those universities. The \SpecialChar LyX team cannot write layout files to support every one of these. There are too many. Fortunately, users can write their own layout files, and many users have done so. Chapter \emph on Installing New Document Classes, Layouts, and Templates \emph default of the \emph on Customization \emph default manual contains information on how to create layout files. \end_layout \begin_layout Subsubsection Modules \begin_inset CommandInset label LatexCommand label name "subsec:Modules" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Modules \end_layout \end_inset \end_layout \begin_layout Standard Modules load additional features that are not by default available in the chosen document class. For example you might want to write Braille (embossed printing) in a document. This is not available in any document class, so you have to load the correspond ing module in the \family sans Modules \family default section of the \family sans Document\SpecialChar menuseparator Settings \family default \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Settings \end_layout \end_inset dialog. Highlighting a module in the dialog will bring up a description of what it does. \end_layout \begin_layout Standard Some modules require \SpecialChar LaTeX packages or file format converters that are not always installed by default. \SpecialChar LyX will warn you if you do not have a required package or converter, and it will tell you what exactly you are missing. You can still use the module while editing your file, but you will not be able to export to PDF or print your document, since \SpecialChar LyX will not be able to compile the \SpecialChar LaTeX file without the missing prerequisites. If you want to be able to produce this kind of output, then you need to install the missing prerequisites and then reconfigure \SpecialChar LyX by selecting \family sans Tools\SpecialChar menuseparator Reconfigure \family default . \begin_inset Index idx status collapsed \begin_layout Plain Layout Reconfiguration of \SpecialChar LyX \end_layout \end_inset See section Installing new \SpecialChar LaTeX files of the \emph on Customization \emph default manual for more information on installing required packages. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Some modules require other modules, and some pairs of modules are incompatible. \SpecialChar LyX will advise you about these things. \end_layout \end_inset \end_layout \begin_layout Subsubsection Local Layout \begin_inset CommandInset label LatexCommand label name "subsec:Local-Layout" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Local Layout \end_layout \end_inset \end_layout \begin_layout Standard Modules are to \SpecialChar LyX much as packages are to \SpecialChar LaTeX : They are intended to be used in a variety of different documents. If you often find yourself needing the same sort of thing in different documents, you should consider writing a module for this purpose. Sometimes, however, a particular document has very special needs, but you need a specific inset or \change_deleted -712698321 1525757388 character \change_inserted -712698321 1525757388 text \change_unchanged style only that one time.

There are several paragraph environments used to create section headings. Different document classes allow different types of section headings. Only two use the \family sans Chapter \family default heading; the rest do not and begin instead with the \family sans Section \family default heading. Some document classes, such as the ones for letters, don't use any section headings. In addition to \family sans Chapter \family default and \family sans Section \family default headings, there are also \family sans Subsection \family default headings, \family sans Subsubsection \family default headings, and so on. We will describe these headings fully in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Headings" \end_inset . \end_layout \begin_layout Subsection Document Layout \begin_inset CommandInset label LatexCommand label name "subsec:Document-Layout" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Document !

That includes the paragraph environments. Some paragraph environments are standard, in so far as all of the document classes have them; but some classes have special paragraph environments. If this is the case, and you change the document class, \SpecialChar LyX will mark the paragraphs whose styles it no longer understands as \begin_inset Quotes eld \end_inset unknown \begin_inset Quotes erd \end_inset . The name of the style is retained, in case you should want to go back to the old class. But these paragraphs will be output with no special formatting, so you will either need to create a new style yourself or else convert these paragraph s manually to a style present in your new document class. \end_layout \begin_layout Section Paragraph Indentation and Separation \begin_inset Index idx status collapsed \begin_layout Plain Layout Paragraph ! Indentation \end_layout \end_inset \end_layout \begin_layout Subsection Introduction \begin_inset CommandInset label LatexCommand label name "sec:Par-indent-intro" \end_inset \end_layout \begin_layout Standard Before describing all of the various paragraph environments, we'd like to say a word or two about paragraph indentation. \end_layout \begin_layout Standard Everyone seems to have their own convention for separating paragraphs. Most Americans indent the first line of a paragraph. Others don't indent but put extra space between the paragraphs. If you choose indentation for paragraphs the \emph on first \emph default paragraph of a section, or after a figure, an equation, a table, a list, etc., is \emph on not \emph default indented. Only a paragraph following another paragraph gets indented. Note that the indentation behavior is different when you use another document language than English. \SpecialChar LaTeX takes care that the indentation follows the rules of the language used. \end_layout \begin_layout Standard The space between paragraphs, like the line spacing, the space between headings and text — in fact, all the spacing for just about everything —is pre-coded into \SpecialChar LyX . As we said, you don't worry about how much space to add between what. \SpecialChar LyX takes care of that. In fact, these pre-coded vertical spacings aren't a single number but a range. That way, \SpecialChar LyX can squish or stretch the space between lines to make sure figures fit on a page with text, so that sections don't start at the bottom of a page, and so on. \begin_inset Foot status collapsed \begin_layout Plain Layout \SpecialChar LaTeX does this when \SpecialChar LyX goes to produce a printable file. \end_layout \end_inset However, pre-coded doesn't mean you can't change them. \SpecialChar LyX gives you the ability globally to change \emph on all \emph default these pre-coded spacings. We will explain more later. \end_layout \begin_layout Subsection Paragraph Separation \begin_inset CommandInset label LatexCommand label name "subsec:Paragraph-Separation" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Paragraph !

If paragraphs have no indentation but use extra space for separation, this button will be ignored (you can't indent a single paragraph by toggling this). \end_layout \begin_layout Standard You should only need to change the indentation method for a single paragraph if you need to do some fine-tuning. \end_layout \begin_layout Subsection Line Spacing \begin_inset Index idx status collapsed \begin_layout Plain Layout Paragraph !

If you don't know \SpecialChar LaTeX , or the concept of a paragraph environment is totally alien to you, we urge you to read the \emph on Tutorial \emph default . The \emph on Tutorial \emph default also contains many more examples than this section does. \end_layout \begin_layout Standard A paragraph environment is simply a \begin_inset Quotes eld \end_inset container \begin_inset Quotes erd \end_inset for a paragraph which gives that paragraph certain properties. This can include a particular style of font, different margins, a numbering scheme, labels, and so on. Additionally, you can \begin_inset Quotes eld \end_inset nest \begin_inset Quotes erd \end_inset the different environments inside one another, allowing one environment to inherit some of the properties of another. The different paragraph environments totally replace the need for messy tab stops, on the fly margin adjustment, and other hangovers from the days of typewriters. There are several paragraph environments that are specific to a particular document type. We will only be covering the most common ones here. \end_layout \begin_layout Standard To choose a new paragraph environment, use the pull-down box \begin_inset Graphics filename clipart/ToolbarEnvBox.png scale 70 clip \end_inset at the left end of the toolbar. \SpecialChar LyX will change the environment of the \emph on entire \emph default paragraph in which the cursor sits. You can also change the environment of an entire group of paragraphs if you select them before choosing the new environment. \end_layout \begin_layout Standard Note that entering \family sans Return \family default will \emph on typically \emph default create a new paragraph using the \family sans Standard \family default paragraph environment. We say \begin_inset Quotes eld \end_inset typically \begin_inset Quotes erd \end_inset because if you are in one of these environments: \end_layout \begin_layout Itemize \family sans Quote \end_layout \begin_layout Itemize \family sans Quotation \end_layout \begin_layout Itemize \family sans Verse \end_layout \begin_layout Itemize \family sans Itemize \end_layout \begin_layout Itemize \family sans Enumerate \end_layout \begin_layout Itemize \family sans Description \end_layout \begin_layout Itemize \family sans List \end_layout \begin_layout Standard \SpecialChar LyX keeps the old paragraph environment when you enter \family sans Return \family default , rather than resetting it to \family sans Standard \family default . Also the nesting depth is preserved (for more on nesting see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Nesting" \end_inset ). \end_layout \begin_layout Subsection Standard \end_layout \begin_layout Standard The default paragraph environment is \family sans Standard \family default for most classes. It creates a plain paragraph. If \SpecialChar LyX resets the paragraph environment, this is the one it chooses. In fact, the paragraph you're reading right now (and most of the ones in this manual) are in the \family sans Standard \family default environment. \end_layout \begin_layout Standard You can nest a paragraph using the \family sans Standard \family default environment in just about anything else, but you can't really nest anything in a \family sans Standard \family default environment. \end_layout \begin_layout Subsection Document Title \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Title \end_layout \end_inset \end_layout \begin_layout Standard A \SpecialChar LaTeX title page has three parts: the title itself, the name(s) of the author(s) and a \begin_inset Quotes eld \end_inset footnote \begin_inset Quotes erd \end_inset for thanks or contact information. For certain types of documents, \SpecialChar LaTeX places all of this on a separate page along with today's date. For other types of documents, the title \begin_inset Quotes eld \end_inset page \begin_inset Quotes erd \end_inset goes at the top of the first page of the document. \end_layout \begin_layout Standard \SpecialChar LyX provides an interface to the title page commands through the paragraph environments \family sans Title \family default , \family sans Author \family default , and \family sans Date \family default . Here's how you use them: \end_layout \begin_layout Itemize Put the title of your document in the \family sans Title \family default environment. \end_layout \begin_layout Itemize Put the author name in the \family sans Author \family default environment. \end_layout \begin_layout Itemize If you want the date to have a certain appearance, want to use a fixed date, or want other text to appear in place of today's date, put that text in the \family sans Date \family default environment. Note that using this environment is optional. If you don't provide any, \SpecialChar LaTeX will automatically insert today's date. If you don't want a date, use the option \family sans Suppress default date on front page \family default in the menu \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Document \begin_inset space ~ \end_inset class \family default . \end_layout \begin_layout Standard You can use footnotes to insert \begin_inset Quotes eld \end_inset thanks \begin_inset Quotes erd \end_inset or contact information. \end_layout \begin_layout Subsection Headings \begin_inset Index idx status collapsed \begin_layout Plain Layout Section headings \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Headings" \end_inset \end_layout \begin_layout Standard There are several paragraph environments for producing section headings. \SpecialChar LyX takes care of the numbering for you. \end_layout \begin_layout Subsubsection Numbered Headings \begin_inset Index idx status collapsed \begin_layout Plain Layout Section headings ! Numbered \end_layout \end_inset \end_layout \begin_layout Standard There are 7 numbered types of section headings. They are: \end_layout \begin_layout Enumerate \family sans Part \end_layout \begin_layout Enumerate \family sans Chapter \end_layout \begin_layout Enumerate \family sans Section \end_layout \begin_layout Enumerate \family sans Subsection \end_layout \begin_layout Enumerate \family sans Subsubsection \end_layout \begin_layout Enumerate \family sans Paragraph \end_layout \begin_layout Enumerate \family sans Subparagraph \end_layout \begin_layout Standard \SpecialChar LyX labels each heading with a series of numbers, separated by periods. The numbers describe where in the document you are. Unlike the other headings, parts are numbered with Latin letters. \end_layout \begin_layout Standard Headings all subdivide your document into different pieces of text. For example, suppose you're writing a book. You group the book into chapters. \SpecialChar LyX does a similar grouping: \end_layout \begin_layout Itemize \family sans Part \family default is divided into either \family sans Chapter \family default s or \family sans Section \family default s \end_layout \begin_layout Itemize \family sans Chapter \family default s are divided into \family sans Section \family default s \end_layout \begin_layout Itemize \family sans Section \family default s are divided into \family sans Subsection \family default s \end_layout \begin_layout Itemize \family sans Subsection \family default s are divided into \family sans Subsubsection \family default s \end_layout \begin_layout Itemize \family sans Subsubsection \family default s are divided into \family sans Paragraph \family default s \end_layout \begin_layout Itemize \family sans Paragraph \family default s are divided into \family sans Subparagraph \family default s \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Not all document types use the \family sans Chapter \family default heading as the maximum sectioning level. In that case the \family sans Section \family default is the top-level heading. \end_layout \end_inset \end_layout \begin_layout Standard So, if you use the \family sans Subsubsection \family default environment to label a new sub-subsection, \SpecialChar LyX labels it with its number, along with the number of the subsection, section and, if applicable, chapter that it's in. For example: the fifth section of the second chapter of this book has the label \begin_inset Quotes eld \end_inset 2.5 \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Subsubsection Unnumbered Headings \begin_inset Index idx status collapsed \begin_layout Plain Layout Section headings ! Unnumbered \end_layout \end_inset \end_layout \begin_layout Standard The unnumbered section headings have a \begin_inset Quotes eld \end_inset * \begin_inset Quotes erd \end_inset at the end of their name. They work the same as their numbered counterparts but will not appear in the table of contents, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:toc" \end_inset . \end_layout \begin_layout Subsubsection Changing the Numbering \begin_inset CommandInset label LatexCommand label name "subsec:Numbering-depth" \end_inset \end_layout \begin_layout Standard You can also alter which sectioning levels get numbered and which ones appear in the Table of Contents. Now, this doesn't remove any of the levels; that's preset in the document class. Just as certain classes start with \family sans Chapter \family default and go down to the \family sans Subparagraph \family default level. Others start at \family sans Section \family default . Similarly, not all document classes number all sectioning levels. Most don't number \family sans Paragraph \family default or \family sans Subparagraph \family default . This is something you can change. \end_layout \begin_layout Standard Open the \family sans Document\SpecialChar menuseparator Settings \family default dialog. \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Settings \end_layout \end_inset Under \family sans Numbering \begin_inset space ~ \end_inset & \begin_inset space ~ \end_inset TOC \family default you will see two counters. The one named \family sans Numbering \family default controls how far down in the sectioning hierarchy \SpecialChar LyX numbers a section heading. The other one controls the appearance of the section headings in the table of contents. \end_layout \begin_layout Subsubsection Short Titles of Headings \begin_inset Index idx status collapsed \begin_layout Plain Layout Section headings ! Short titles \end_layout \end_inset \begin_inset Argument 1 status collapsed \begin_layout Plain Layout Short Titles \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Short-Titles" \end_inset \end_layout \begin_layout Standard Some section or chapter titles, such as this one, can get quite long. This can cause trouble when there is limited horizontal space. For example, if the header of the page is set to show the current section title, a long title will protrude over the page margins and look awful. \end_layout \begin_layout Standard \SpecialChar LaTeX allows you to specify a short title for section headings. This short title is used in the header and in the actual table of contents, avoiding the problem mentioned. To specify a short title, set the cursor behind the title and use the menu \family sans Insert\SpecialChar menuseparator Short \begin_inset space ~ \end_inset Title \family default . This will insert a box labeled \begin_inset Quotes eld \end_inset Short \begin_inset space ~ \end_inset Title \begin_inset Quotes erd \end_inset which you can use to enter the short title text. This also works for captions inside floats. There can only be one short title per title. \end_layout \begin_layout Standard The title of this section is a good example of using this feature. \end_layout \begin_layout Subsubsection Special Information \end_layout \begin_layout Standard The following information applies to all section headings: \end_layout \begin_layout Itemize You cannot do any nesting with these environments. \end_layout \begin_layout Itemize You cannot use a margin note in any of these environments. \end_layout \begin_layout Itemize You can only use inline math in these environments. \end_layout \begin_layout Itemize You can use labels and cross-references to refer to their numbers. \end_layout \begin_layout Subsection Quotes and Poetry \end_layout \begin_layout Standard \SpecialChar LyX has three paragraph environments for writing poetry and quotations. They are \family sans Quote \family default , \family sans Quotation \family default , and \family sans Verse \family default . Forget the days of changing line spacing and twiddling with margins. These three paragraph environments already have those changes built-in. They all widen the left margin and add a bit of extra space above and below the text they contain. They also allow nesting, so you can put a \family sans Verse \family default in a \family sans Quotation \family default , as well as in some other paragraph environments. \end_layout \begin_layout Standard There is another feature of these three paragraph environments: they do \emph on not \emph default reset to \family sans Standard \family default when you start a new paragraph. So, you can type in that poem and merrily enter \family sans Return \family default without worrying about the paragraph environment changing on you. Of course, that means that, once you are done typing in that poem, you have to change back to the \family sans Standard \family default environment yourself. \end_layout \begin_layout Subsubsection Quote and Quotation \begin_inset CommandInset label LatexCommand label name "sec:Quote" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Quotation \end_layout \end_inset \end_layout \begin_layout Standard Now that we've described the similarities of these three environments, it's time for the differences. \family sans Quote \family default and \family sans Quotation \family default are identical except for one difference: \family sans Quote \family default uses extra spacing to separate paragraphs and never indents the first line. \family sans Quotation \family default \emph on always \emph default indents the first line of a paragraph and uses the same line spacing throughout. \end_layout \begin_layout Standard Here's an example of the \family sans Quote \family default environment: \end_layout \begin_layout Quote This is in the \family sans Quote \family default environment. I can keep writing, extending this line out further and further until it wraps. See – no indentation! \end_layout \begin_layout Quote Here's the second paragraph of this quote. Again, there's no indentation, but there is extra space between me and the other paragraph. \end_layout \begin_layout Standard Here's another example, this time in the \family sans Quotation \family default environment: \end_layout \begin_layout Quotation This is in the \family sans Quotation \family default environment. If I keep writing, you will see the indentation. If your country uses a writing style that indicates new paragraphs by indenting the first line, then \family sans Quotation \family default is the environment for you! Well, you'd use it \emph on if \emph default you were quoting other text. \end_layout \begin_layout Quotation Here's a new paragraph. I could ramble on and on, like a politician at election time. If I did that, though, you'd get bored. \end_layout \begin_layout Standard As the examples show, \family sans Quote \family default is for those people who use extra space to separate paragraphs. They should put quotes in the \family sans Quote \family default environment. Those who use indentation to mark a new paragraph should use the \family sans Quotation \family default paragraph environment for quoted text. \end_layout \begin_layout Subsubsection Verse \begin_inset Index idx status collapsed \begin_layout Plain Layout Paragraph ! Verse \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Poetry \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Verse" \end_inset \end_layout \begin_layout Standard \family sans Verse \family default is a paragraph environment for poetry, rhymes, verses, and so on. Here's an example: \end_layout \begin_layout Verse This is in Verse \begin_inset Newline newline \end_inset Which I did not rehearse! \end_layout \begin_layout Verse It could be much worse. This line could be long, very long, oh so long, so very long that it wraps around. It looks okay on screen, but in the printed version, the extra lines are indented a bit more than the first. Okay, so it's turned to prose and doesn't rhyme anymore. So sue me. \end_layout \begin_layout Verse To break a line \begin_inset Newline newline \end_inset And make things look fine \begin_inset Newline newline \end_inset Use \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset . \end_layout \begin_layout Standard As you can see, \family sans Verse \family default does not indent both margins. Each stanza of the verse or poem is in its own paragraph. To separate the individual lines of a stanza, use the shortcut \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset . \end_layout \begin_layout Subsection Lists \begin_inset Index idx status collapsed \begin_layout Plain Layout Lists \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Lists" \end_inset \end_layout \begin_layout Standard \SpecialChar LyX has four different paragraph environments for creating different kinds of lists. In the \family sans Itemize \family default and \family sans Enumerate \family default environments, \SpecialChar LyX labels your list items with bullets or numbers, respectively. In the \family sans Description \family default and \family sans List \family default environments, \SpecialChar LyX lets you provide your own label. We will present the individual details of each type of list next after describing some general features of all four of them. \end_layout \begin_layout Subsubsection General Features \end_layout \begin_layout Standard The four paragraph environments for lists differ from the other environments in several ways. First, \SpecialChar LyX treats each paragraph as a list item. Hitting \family sans Return \family default does \emph on not \emph default reset the environment to \family sans Standard \family default but keeps the current environment and creates a new list item. The nesting depth is thereby kept. If you want to keep the paragraph environment but reset the current nesting depth, you can use \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset . If you do this at the top level of a list, it returns you to the \family sans Standard \family default environment. \end_layout \begin_layout Standard You can nest lists of any type inside one another. In fact, \SpecialChar LyX changes the labels on some list items depending on how it is nested. If you intend to use any of the list paragraph environments, we suggest you read all of section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Nesting" \end_inset . \end_layout \begin_layout Subsubsection Itemize \begin_inset Index idx status collapsed \begin_layout Plain Layout Lists ! Itemize \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Itemize" \end_inset \end_layout \begin_layout Standard The first type of list we will describe in detail is the \family sans Itemize \family default paragraph environment. It has the following properties: \end_layout \begin_layout Itemize Each item has a particular bullet or symbol as its label. \end_layout \begin_deeper \begin_layout Itemize \SpecialChar LyX uses the same symbol for all of the items in a given nesting level. \end_layout \begin_layout Itemize The symbol appears at the beginning of the first line. \end_layout \end_deeper \begin_layout Itemize The items can have any length. \SpecialChar LyX automatically offsets the left margin of each item. The offset is always relative to whatever environment the \family sans Itemize \family default list may be in. \end_layout \begin_layout Itemize If you nest an \family sans Itemize \family default environment inside another \family sans Itemize \family default environment, the label changes to a new symbol. \end_layout \begin_deeper \begin_layout Itemize There are four different symbols for up to a four-fold nesting. \end_layout \begin_layout Itemize \SpecialChar LyX always shows the same symbol on screen. \end_layout \begin_layout Itemize See section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Nesting" \end_inset for a full explanation of nesting. \end_layout \end_deeper \begin_layout Standard Of course, that explanation was also an example of an \family sans Itemize \family default list. The \family sans Itemize \family default environment is best suited for lists where the order doesn't matter. \end_layout \begin_layout Standard We said that different levels use different symbols as their label. Here's an example of all four possible symbols. \end_layout \begin_layout Itemize The label for the first level \family sans Itemize \family default is a large black dot, or bullet. \end_layout \begin_deeper \begin_layout Itemize The label for the second level is a dash. \end_layout \begin_deeper \begin_layout Itemize The label for the third is an asterisk. \end_layout \begin_deeper \begin_layout Itemize The label for the fourth is a centered dot. \end_layout \end_deeper \begin_layout Itemize Back out to the third level. \end_layout \end_deeper \begin_layout Itemize Back to the second level. \end_layout \end_deeper \begin_layout Itemize Back to the outermost level. \end_layout \begin_layout Standard These are the default labels for an \family sans Itemize \family default list. You can customize how these labels are displayed in the output in the \family sans Document\SpecialChar menuseparator Settings \family default dialog in the submenu \family sans Bullets \family default . \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Settings \end_layout \end_inset These customizations are not displayed in \SpecialChar LyX . \end_layout \begin_layout Standard Notice how the space between items decreases with increasing depth. We will explain nesting and all the tricks you can do with different depths in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Nesting" \end_inset . \end_layout \begin_layout Subsubsection Enumerate \begin_inset Index idx status collapsed \begin_layout Plain Layout Lists ! Enumerate \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Enumerate" \end_inset \end_layout \begin_layout Standard The \family sans Enumerate \family default environment is used to create numbered lists and outlines. It has these properties: \end_layout \begin_layout Enumerate Each item has a numeral as its label. \end_layout \begin_deeper \begin_layout Enumerate The label type depends on the nesting depth. \end_layout \end_deeper \begin_layout Enumerate \SpecialChar LyX automatically counts the items for you and updates the label as appropriate. \end_layout \begin_layout Enumerate Each new \family sans Enumerate \family default environment resets the counter to one. \end_layout \begin_layout Enumerate Like the \family sans Itemize \family default environment, the \family sans Enumerate \family default environment: \end_layout \begin_deeper \begin_layout Enumerate Offsets the items relative to the left margin. Items can have any length. \end_layout \begin_layout Enumerate Reduces the space between items as the nesting depth increases. \end_layout \begin_layout Enumerate Uses different types of labels depending on the nesting depth. \end_layout \begin_layout Enumerate Allows up to a four-fold nesting. \end_layout \end_deeper \begin_layout Standard Unlike the \family sans Itemize \family default environment, \family sans Enumerate \family default shows the different labels for each item in \SpecialChar LyX . Here is how \SpecialChar LyX labels the four different levels in an \family sans Enumerate \family default : \end_layout \begin_layout Enumerate The first level of an \family sans Enumerate \family default uses Arabic numerals followed by a period. \end_layout \begin_deeper \begin_layout Enumerate The second level uses lower case letters surrounded by parentheses. \end_layout \begin_deeper \begin_layout Enumerate The third level uses lower-case Roman numerals followed by a period. \end_layout \begin_deeper \begin_layout Enumerate The fourth level uses capital letters followed by a period. \end_layout \begin_layout Enumerate Again, notice the decrease in the spacing between items as the nesting depth increases. \end_layout \end_deeper \begin_layout Enumerate Back to the third level \end_layout \end_deeper \begin_layout Enumerate Back to the second level. \end_layout \end_deeper \begin_layout Enumerate Back to the outermost level. \end_layout \begin_layout Standard You can customize the type of numbering used in the \family sans Enumerate \family default environment, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Customized-Lists" \end_inset . Such customization only shows up in the printed version, not in \SpecialChar LyX . \end_layout \begin_layout Standard There is more to nesting \family sans Enumerate \family default environments than we've stated here. You should read section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Nesting" \end_inset to learn more about nesting. \end_layout \begin_layout Subsubsection Description \begin_inset Index idx status collapsed \begin_layout Plain Layout Lists ! Description \end_layout \end_inset \end_layout \begin_layout Standard Unlike the previous two environments, the \family sans Description \family default list has no fixed label. Instead, \SpecialChar LyX uses the first \begin_inset Quotes eld \end_inset word \begin_inset Quotes erd \end_inset of the first line as the label. Here's an example: \end_layout \begin_layout Description Example: This is an example of the \family sans Description \family default environment. \end_layout \begin_layout Standard \SpecialChar LyX typesets the label in boldface and puts extra space between it and the rest of the line. \end_layout \begin_layout Standard With the first \begin_inset Quotes eld \end_inset word \begin_inset Quotes erd \end_inset it is meant that the first usage of the \family sans Space \family default key ends the label if you are at the beginning of the first line of an item. If you need to use more than one word in a label use a \family sans Protected Space \family default . (Use either \begin_inset Info type "shortcut" arg "command-alternatives math-space ; space-insert protected" \end_inset or the menu \family sans Insert\SpecialChar menuseparator Formatting\SpecialChar menuseparator Protected \begin_inset space ~ \end_inset Space \family default ; see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Protected-Space" \end_inset for more information.) Here is an example: \end_layout \begin_layout Description Second \begin_inset space ~ \end_inset Example: This one shows how to use a \family sans Protected \begin_inset space ~ \end_inset Space \family default in the label of a \family sans Description \family default list item. \end_layout \begin_layout Description Usage: You should use the \family sans Description \family default environment for things like definitions and theorems. Use it when you need to make one word in particular stand out in the text that describes it. It's not a good idea to use a \family sans Description \family default environment when you have an entire sentence that you want to describe. You're better off using \family sans Itemize \family default or \family sans Enumerate \family default and nesting several \family sans Standard \family default paragraphs into them. \end_layout \begin_layout Description Nesting: You can nest \family sans Description \family default environments inside one another, nest them in other types of lists, and so on. \end_layout \begin_layout Standard Notice that after the first line, \SpecialChar LyX indents subsequent lines, offsetting them from the first line. \end_layout \begin_layout Subsubsection Labeling \begin_inset Index idx status collapsed \begin_layout Plain Layout Lists ! Labeling \end_layout \end_inset \end_layout \begin_layout Standard The \family sans Labeling \family default environment is a \SpecialChar LyX extension to \SpecialChar LaTeX . \end_layout \begin_layout Standard Like the \family sans Description \family default list the \family sans Labeling \family default list has user-defined labels for each list item but it provides some additional features. Here are its properties: \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 item \begin_inset space ~ \end_inset labels \SpecialChar LyX uses the first \begin_inset Quotes eld \end_inset word \begin_inset Quotes erd \end_inset of each line as the item label. The first \family sans Space \family default after the beginning of the first line of an item marks the end of the label. If you need to use more than one word in an item label, use a protected space as described above. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 margins As you can see, \SpecialChar LyX uses different margins for the item label and the body of the item text. The body of the text has a larger left margin, which is equal to the default label width plus a little extra space. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 label \begin_inset space ~ \end_inset width \SpecialChar LyX uses the width of the label, or the default width, whatever is larger. If the label width is larger, the label \begin_inset Quotes eld \end_inset extends \begin_inset Quotes erd \end_inset into the first line. In other words, the text of the first line isn't aligned with the left margin of the rest of the item text. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 default \begin_inset space ~ \end_inset width You can set the default label width to ensure that the text of all items in a \family sans Labeling \family default environment has the same left margin. \begin_inset Newline newline \end_inset To change the default width, select all items in the list. Now open the \family sans Edit\SpecialChar menuseparator Paragraph \begin_inset space ~ \end_inset Settings \family default dialog (toolbar button \begin_inset Info type "icon" arg "layout-paragraph" \end_inset ). The text in the box \family sans Longest \begin_inset space ~ \end_inset label \family default determines the default label width. You can use the text of your largest label here, but you can also use the letter \begin_inset Quotes eld \end_inset M \begin_inset Quotes erd \end_inset multiple times instead. M is the widest character and is a standard unit of widths in \SpecialChar LaTeX . By using \begin_inset Quotes eld \end_inset M \begin_inset Quotes erd \end_inset as the unit of width you don't need to keep changing the contents of \family sans Longest \begin_inset space ~ \end_inset label \family default every time you alter a label in a \family sans List \family default environment. \begin_inset Newline newline \end_inset The predefined default width is the length of \begin_inset Quotes eld \end_inset 00.00.0000 \begin_inset Quotes erd \end_inset (equal to 6 \begin_inset space ~ \end_inset M). \end_layout \begin_layout Standard You should use the \family sans Labeling \family default list the same way as the \family sans Description \family default list: When you need one word to stand out from the text that describes it. The \family sans Labeling \family default environment gives you another way to do this, using a different overall layout. \end_layout \begin_layout Standard You can nest \family sans Labeling \family default lists inside one another, nest them in other types of lists, and so on. They work just like the other list paragraph environments. Read section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Nesting" \end_inset to learn about nesting. \end_layout \begin_layout Standard There is yet another feature of the \family sans Labeling \family default list: As you can see in the examples, \SpecialChar LyX left-justifies the item labels by default. You can use additional \family sans HFills \family default to change how \SpecialChar LyX justifies the item label. \family sans Hfills \family default are documented in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Horizontal-Space" \end_inset . Here are some examples: \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 Left The default for \family sans Labeling \family default item labels. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \begin_inset space \hfill{} \end_inset Right One \family sans HFill \family default at the beginning of the label right justifies it. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \begin_inset space \hfill{} \end_inset Center \begin_inset space \hfill{} \end_inset One \family sans HFill \family default at the beginning of the label and one at the end centers it. \end_layout \begin_layout Subsection Customized Lists \begin_inset CommandInset label LatexCommand label name "subsec:Customized-Lists" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Lists !

To use the letter class, you need to use specific paragraph environments in a specific order, otherwise \SpecialChar LaTeX gags on the document. In contrast, you can use the \family sans Address \family default and \family sans Right \begin_inset space ~ \end_inset Address \family default paragraph environments anywhere with no problem. You can even nest them inside other environments, though you can't nest anything in them. \end_layout \begin_layout Standard Of course, you're not limited to using \family sans Address \family default and \family sans Right \begin_inset space ~ \end_inset Address \family default for letters only. \family sans Right \begin_inset space ~ \end_inset Address \family default , in particular, is useful for creating article titles like those used in some European academic papers. \end_layout \begin_layout Subsubsection Usage \begin_inset CommandInset label LatexCommand label name "sec:Address-Usage" \end_inset \end_layout \begin_layout Standard The \family sans Address \family default environment formats text in the style of an address, which is also used for the opening and signature in some countries. Similarly, the \family sans Right \begin_inset space ~ \end_inset Address \family default environment formats text in the style of a right-justified address, which is used for the sender's address and today's date in some countries. Here's an example of each: \end_layout \begin_layout Right Address Right Address \begin_inset Newline newline \end_inset Who I am \begin_inset Newline newline \end_inset Where I am \begin_inset Newline newline \end_inset When is it? What is today? \end_layout \begin_layout Standard That was \family sans Right \begin_inset space ~ \end_inset Address \family default . Notice that the lines all have the same left margin, which \SpecialChar LyX sets to fit the largest block of text on a single line. Here's an example of the \family sans Address \family default environment: \end_layout \begin_layout Address Who are you \begin_inset Newline newline \end_inset Where do I send this \begin_inset Newline newline \end_inset Your post office and country \end_layout \begin_layout Standard As you can see, both \family sans Address \family default and \family sans Right \begin_inset space ~ \end_inset Address \family default add extra space between themselves and the next paragraph. If you enter \family sans Return \family default in either of these environments, \SpecialChar LyX resets the nesting depth and sets the environment to \family sans Standard \family default . This makes sense, since \family sans Return \family default is the \family typewriter paragraph-break \family default function, and the individual lines of an address are not paragraphs. Thus, you have to use \family typewriter break-line \family default ( \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset or \family sans Insert\SpecialChar menuseparator Formatting\SpecialChar menuseparator Ragged \begin_inset space ~ \end_inset Line \begin_inset space ~ \end_inset Break \family default ) to start a new line in an \family sans Address \family default or \family sans Right \begin_inset space ~ \end_inset Address \family default environment. \end_layout \begin_layout Subsection Academic Writing \end_layout \begin_layout Standard Most academic writing begins with an abstract and ends with a bibliography or list of references. \SpecialChar LyX contains paragraph environments for both of these. \end_layout \begin_layout Subsubsection Abstract \begin_inset Index idx status collapsed \begin_layout Plain Layout Abstracts \end_layout \end_inset \end_layout \begin_layout Standard The \family sans Abstract \family default environment is used for the abstract of an article. Technically, you could use this environment anywhere, but you really should only use it at the beginning of the document, after the title. Also, don't bother trying to nest \family sans Abstract \family default in anything else or \emph on vice versa \emph default . It will not work. The \family sans Abstract \family default environment is only useful in the article and report document classes. The book document classes ignores the \family sans Abstract \family default completely, and it's utterly silly to use \family sans Abstract \family default in a letter document class. \end_layout \begin_layout Standard The \family sans Abstract \family default environment does several things for you. First, it puts the centered label \begin_inset Quotes eld \end_inset Abstract \begin_inset Quotes erd \end_inset above the text. The label and the text of the abstract are separated by some extra vertical space. Second, it typesets everything in a smaller font, just as you'd expect. Lastly, it adds a bit of extra vertical space between the abstract and the subsequent text. Well, that's how it will appear on the \SpecialChar LyX screen. The actual appearance in the output depends on the document class you are using. \end_layout \begin_layout Standard Starting a new paragraph by entering \family sans Return \family default does not reset the paragraph environment. The new paragraph will still be in the \family sans Abstract \family default environment. So, you will have to change the paragraph environment yourself when you finish entering the abstract of your document. \end_layout \begin_layout Standard \begin_inset Float figure wide false sideways false status open \begin_layout Plain Layout \align center \begin_inset Graphics filename clipart/Abstract.pdf \end_inset \end_layout \begin_layout Plain Layout \begin_inset Caption Standard \begin_layout Plain Layout \begin_inset CommandInset label LatexCommand label name "fig:Paragraph-in-the" \end_inset Paragraph in the \family sans Abstract \family default environment \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard We would love to demonstrate the \family sans Abstract \family default environment, but since this document is in the \begin_inset Quotes eld \end_inset book \begin_inset Quotes erd \end_inset class, we can't do this. We inserted it therefore as figure \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "fig:Paragraph-in-the" \end_inset . If you have never heard of an \begin_inset Quotes eld \end_inset abstract \begin_inset Quotes erd \end_inset before, you can safely ignore this environment. \end_layout \begin_layout Subsubsection Bibliography \begin_inset Index idx status collapsed \begin_layout Plain Layout Bibliography \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Biblio_environment" \end_inset \end_layout \begin_layout Standard The \family sans Bibliography \family default environment is used to list references. Technically, you could use this environment anywhere, but you really should only use it at the end of the document. Nesting \family sans Bibliography \family default in anything else or \emph on vice versa \emph default will not work. \end_layout \begin_layout Standard When you first open a \family sans Bibliography \family default environment, \SpecialChar LyX adds a large vertical space, followed by the heading \begin_inset Quotes eld \end_inset Bibliography \begin_inset Quotes erd \end_inset or \begin_inset Quotes eld \end_inset References, \begin_inset Quotes erd \end_inset depending on the document class. The heading is in a large boldface font. Each paragraph of the \family sans Bibliography \family default environment is a bibliography entry. Thus, entering \family sans Return \family default does not reset the paragraph environment. Each new paragraph is still in the \family sans Bibliography \family default environment. \end_layout \begin_layout Standard There is another, usually better way to include references in your document by using a Bib\SpecialChar TeX database. For more information on that, and for a detailed description of \SpecialChar LyX 's bibliography handling, have a look at section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Bibliography" \end_inset . \end_layout \begin_layout Subsection Special Environments \end_layout \begin_layout Standard \SpecialChar LyX provides two environments that can be used to emulate the behavior of a computer console/terminal and a typewriter. \end_layout \begin_layout Subsubsection \SpecialChar LyX \family sans -Code \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LyX -Code \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:LyX-Code" \end_inset \end_layout \begin_layout Standard The \family sans \SpecialChar LyX -Code \family default environment is a \SpecialChar LyX extension. It type-sets text in a typewriter-style font. It also treats the \family sans Space \family default key as a fixed whitespace. \begin_inset Foot status collapsed \begin_layout Plain Layout In the \family sans \SpecialChar LyX -Code \family default environment, the \family sans Space \family default key is treated as a \family sans Protected \begin_inset space ~ \end_inset Blank \family default instead of an end-of-word marker. \end_layout \end_inset \family sans \SpecialChar LyX -Code \family default , \family sans Verbatim \family default and \family sans Verbatim \family default * are the only environments in which you can type multiple whitespaces in \SpecialChar LyX . If you need to insert blank lines, you will still need to use \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset (the \family typewriter break-line \family default function). \family sans Return \family default breaks paragraphs. Note, however, that \family sans Return \family default does not reset the paragraph environment. So, when you finish using the \family sans \SpecialChar LyX -Code \family default environment, you will need to change the paragraph environment yourself. Also, you can nest the \family sans \SpecialChar LyX -Code \family default environment inside of others. \end_layout \begin_layout Standard There are a few quirks with this environment: \end_layout \begin_layout Itemize You cannot use \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset at the beginning of a new paragraph (i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space \space{} \end_inset you can't follow \family sans Return \family default with a \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset ). \end_layout \begin_layout Itemize You cannot follow a \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset with a \family sans Space \family default but with a \begin_inset Info type "shortcut" arg "command-alternatives math-space ; space-insert protected" \end_inset . \end_layout \begin_layout Itemize You cannot have an empty paragraph or an empty line. You must put at least one \family sans Space \family default in any line you want blank. Otherwise, \SpecialChar LaTeX generates errors. \end_layout \begin_layout Itemize You cannot get the typewriter double quotes by typing \family sans " \family default since that will insert \emph on real \emph default quotes. You get the typewriter double quotes with \begin_inset Info type "shortcut" arg "self-insert \"" \end_inset . \end_layout \begin_layout Standard Here is an example: \end_layout \begin_layout LyX-Code #include \end_layout \begin_layout LyX-Code \end_layout \begin_layout LyX-Code int main(void) \end_layout \begin_layout LyX-Code { \end_layout \begin_layout LyX-Code printf("Hello World! \backslash n"); \end_layout \begin_layout LyX-Code return 0; \end_layout \begin_layout LyX-Code } \end_layout \begin_layout Standard This is just the standard \begin_inset Quotes eld \end_inset Hello world! \begin_inset Quotes erd \end_inset program. \end_layout \begin_layout Standard \family sans \SpecialChar LyX -Code \family default has one purpose: to typeset code, such as program source, shell scripts and so on.

Compared to \family sans \SpecialChar LyX -Code \family default the \family sans Space \family default key is treated like a normal space in text (not as a protected space) and you can have empty lines. In contrary to \family sans \SpecialChar LyX -Code, \family default \family sans Verbatim \family default cannot \end_layout \begin_layout Itemize have a certain language and a text style \end_layout \begin_layout Itemize contain hyperlinks, boxes, foot- and margin notes, notes, math, citations, index- and nomenclature entries, labels, tables, graphics, listings, floats and \SpecialChar TeX Code \end_layout \begin_layout Standard Because of these properties \family sans Verbatim \family default works like a typewriter. Here is an example: \end_layout \begin_layout Verbatim This is Verbatim. \end_layout \begin_layout Verbatim \noindent \align block The following 2 lines are empty: \end_layout \begin_layout Verbatim \end_layout \begin_layout Verbatim \end_layout \begin_layout Verbatim Almost everything is allowed in Verbatim:"%&$§#~'` \backslash }][{| \end_layout \begin_layout Standard The \family sans Verbatim* \family default environment is identical to \family sans Verbatim \family default with the difference that spaces appear in the output as the character ' \begin_inset space \textvisiblespace{} \end_inset '.

Environments \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Nesting" \end_inset \end_layout \begin_layout Subsection Introduction \end_layout \begin_layout Standard \SpecialChar LyX treats text as a unified block with a particular context and specific propertie s. This allows you to create blocks that inherit some of the properties of another block. For example you have three main points in an outline, but point #2 also has two subpoints. In other words, you have a list inside of another list, with the inner list \begin_inset Quotes eld \end_inset attached \begin_inset Quotes erd \end_inset to item #2: \end_layout \begin_layout Enumerate one \end_layout \begin_layout Enumerate two \end_layout \begin_deeper \begin_layout Enumerate sublist – item #1 \end_layout \begin_layout Enumerate sublist – item #2 \end_layout \end_deeper \begin_layout Enumerate three \end_layout \begin_layout Standard You put a list inside a list by nesting one list inside the other. Nesting an environment is quite simple: Select \family sans Edit\SpecialChar menuseparator Increase \begin_inset space ~ \end_inset List \begin_inset space ~ \end_inset Depth \family default or \family sans Decrease \begin_inset space ~ \end_inset List \begin_inset space ~ \end_inset Depth \family default to change the nesting depth (the status bar will tell you how far you are nested). Instead of the menu, you can also use the toolbar buttons \begin_inset Info type "icon" arg "depth-increment" \end_inset and \begin_inset Info type "icon" arg "depth-decrement" \end_inset or the key bindings \family sans Tab \family default and \family sans Shift+Tab \family default or \begin_inset Info type "shortcut" arg "depth-increment" \end_inset and \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset . The change will work on the current selection, if you have made one (allowing you to change the nesting of several paragraphs at once), or the current paragraph. \end_layout \begin_layout Standard Note that \SpecialChar LyX only changes the nesting depth if it can. If it is invalid to do so, nothing happens if you try to change the depth. Additionally, if you change the depth of one paragraph, it affects the depth of every paragraph nested inside of it. \end_layout \begin_layout Standard Nesting isn't limited to lists. In \SpecialChar LyX , you can nest just about anything inside anything else, as you're about to find out. This is the real power of nesting paragraph environments. \end_layout \begin_layout Subsection What You Can and Can't Nest \end_layout \begin_layout Standard Before we fire a list of paragraph environments at you, we need to tell you a little bit more about how nesting works. \end_layout \begin_layout Standard The question of nesting a paragraph environment is a bit more complicated than a simple yes or no. There are three types of paragraph environments: \end_layout \begin_layout Itemize Completely unnestable \end_layout \begin_layout Itemize Fully nestable, you can nest them inside things and you can also nest other things inside them. \end_layout \begin_layout Itemize A third type, you can nest them into other environments, but you can't nest anything into them. \end_layout \begin_layout Standard Here's a list of the three types of nesting behavior, and which paragraph environments have them: \end_layout \begin_layout Description Unnestable Can't nest them.

They are: \end_layout \begin_layout Itemize equations \end_layout \begin_layout Itemize tables \end_layout \begin_layout Itemize figures \end_layout \begin_layout Standard ( \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Figures and tables in \family sans Floats \family default are not affected by this. \end_layout \end_inset Have a look at section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Floats" \end_inset for more information about \family sans Floats \family default .) \end_layout \begin_layout Standard \SpecialChar LyX can treat these three objects as either a word or as a paragraph. If a figure, table, or an equation is inline, it goes wherever the paragraph it is in goes. \end_layout \begin_layout Standard On the other hand, if you have an equation, figure or table in a \begin_inset Quotes eld \end_inset paragraph \begin_inset Quotes erd \end_inset of its own, it behaves just like a \begin_inset Quotes eld \end_inset nestable-inside \begin_inset Quotes erd \end_inset paragraph environment. You can nest it into any environment, but you obviously can't nest anything into it. \end_layout \begin_layout Standard Here's an example with a table: \end_layout \begin_layout Enumerate Item One \end_layout \begin_deeper \begin_layout Enumerate This is (a) and it's nested. \end_layout \begin_deeper \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \begin_layout Standard \align center \begin_inset Tabular \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none a \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none b \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none c \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none d \end_layout \end_inset \end_inset \end_layout \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \end_deeper \begin_layout Enumerate This is (b). The table is actually nested inside (a). \end_layout \end_deeper \begin_layout Enumerate Back out again. \end_layout \begin_layout Standard If we hadn't nested the table at all, the list would look like this: \end_layout \begin_layout Enumerate Item One \end_layout \begin_deeper \begin_layout Enumerate This is (a) and it's nested. \end_layout \end_deeper \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \begin_layout Standard \align center \begin_inset Tabular \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none a \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none b \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none c \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none d \end_layout \end_inset \end_inset \end_layout \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \begin_layout Enumerate This is (b).

In fact, it's not nested at all. \end_layout \begin_layout Enumerate Back out again. \end_layout \begin_layout Standard Notice how item (b) is not only no longer nested, but is also the first item of a new list! \end_layout \begin_layout Standard There's another trap you can fall into: Nesting the table, but not going deep enough. \SpecialChar LyX then turns anything after the table into a new sublist. \end_layout \begin_layout Enumerate Item One \end_layout \begin_deeper \begin_layout Enumerate This is (a) and it's nested. \end_layout \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \begin_layout Standard \align center \begin_inset Tabular \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none a \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none b \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none c \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none d \end_layout \end_inset \end_inset \end_layout \end_deeper \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \begin_layout Enumerate This is (b). The table is actually nested inside Item One, but \emph on not \emph default inside (a). \end_layout \begin_layout Enumerate Back out again. \end_layout \begin_layout Standard As you can see, item (b) turned into the first item of a new list, but a new list \emph on inside \emph default item 1. The same thing would have happened to a figure or an equation. So, if you nest tables, figures or equations, make sure you go to the right depth! \end_layout \begin_layout Subsection Usage and General Features \end_layout \begin_layout Standard Speaking of levels, \SpecialChar LyX can perform up to a six-fold nesting. In other words, \begin_inset Quotes eld \end_inset level #6 \begin_inset Quotes erd \end_inset is the innermost possible depth. Here's an example to illustrate what we mean: \end_layout \begin_layout Enumerate level #1 – outermost \end_layout \begin_deeper \begin_layout Enumerate level #2 \end_layout \begin_deeper \begin_layout Enumerate level #3 \end_layout \begin_deeper \begin_layout Enumerate level #4 \end_layout \begin_deeper \begin_layout Itemize level #5 \end_layout \begin_deeper \begin_layout Itemize level #6 \end_layout \end_deeper \end_deeper \end_deeper \end_deeper \end_deeper \begin_layout Standard There are two exceptions to the six-fold nesting limit, and you can see both of them in the example. Unlike the other fully-nestable environments, you can only perform a four-fold nesting with the \family sans Enumerate \family default and \family sans Itemize \family default environments. For example, if we tried to nest another \family sans Enumerate \family default list inside item \begin_inset Quotes eld \end_inset A. \begin_inset Quotes erd \end_inset , we would get errors. \end_layout \begin_layout Subsection Some Examples \begin_inset Index idx status collapsed \begin_layout Plain Layout Nesting ! Examples \end_layout \end_inset \end_layout \begin_layout Standard The best way to explain just what you can do with nesting is by illustration. We have several examples of nested environments. In them, we explain how we created the example, so that you can reproduce them. \end_layout \begin_layout Subsubsection Example 1: The Six-fold Way and Mixed Nesting \end_layout \begin_layout Labeling \labelwidthstring MMM #1-a This is the outermost level. It's a \family sans List \family default environment. \end_layout \begin_deeper \begin_layout Labeling \labelwidthstring MMM #2-a This is level #2. We created it by using \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset followed by \begin_inset Info type "shortcut" arg "depth-increment" \end_inset . \end_layout \begin_deeper \begin_layout Labeling \labelwidthstring MMM #3-a This is level #3. This time, we just enter \family sans Return \family default , then used \begin_inset Info type "shortcut" arg "depth-increment" \end_inset twice in a row. We could have also created it the same way as we did the previous level, by entering \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset followed by \begin_inset Info type "shortcut" arg "depth-increment" \end_inset . \end_layout \begin_deeper \begin_layout Standard This is actually a \family sans Standard \family default environment, nested inside of \begin_inset Quotes eld \end_inset #3-a \begin_inset Quotes erd \end_inset . So, it's at level #4. We did this by entering \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset , then \begin_inset Info type "shortcut" arg "depth-increment" \end_inset , then changing the paragraph environment to \family sans Standard \family default . Do this to create list items with more than one paragraph — it also works for the \family sans Description \family default , \family sans Enumerate \family default , and \family sans Itemize \family default environments! \end_layout \begin_layout Standard Here's another \family sans Standard \family default paragraph, also at level #4, made with just a \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset . \end_layout \begin_layout Labeling \labelwidthstring MMM #4-a This is level #4. We enter \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset and changed the paragraph environment back to \family sans List \family default . Remember — we can't nest anything inside a \family sans Standard \family default environment, which is why we're still at level #4. However, we \emph on can \emph default keep nesting things inside \begin_inset Quotes eld \end_inset #3-a \begin_inset Quotes erd \end_inset . \end_layout \begin_deeper \begin_layout Labeling \labelwidthstring MMM #5-a This is level #5\SpecialChar ldots \end_layout \begin_deeper \begin_layout Labeling \labelwidthstring MMM #6-a \SpecialChar ldots and this is level #6. By now, you should know how we made these two. \end_layout \end_deeper \begin_layout Labeling \labelwidthstring MMM #5-b Back to level #5. Just enter \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset followed by a \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset . \end_layout \end_deeper \begin_layout Labeling \labelwidthstring MMM #4-b After another \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset followed by a \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset , we're back at level #4. \end_layout \end_deeper \begin_layout Labeling \labelwidthstring MMM #3-b Back to level #3. By now it should be obvious how we did this. \end_layout \end_deeper \begin_layout Labeling \labelwidthstring MMM #2-b Back to level #2. \end_layout \end_deeper \begin_layout Labeling \labelwidthstring MMM #1-b And last, back to the outermost level, #1. After this sentence, we will enter \family sans Return \family default and change the paragraph environment back to \family sans Standard \family default to end the list. \end_layout \begin_layout Standard We could have also used the \family sans Description \family default , \family sans Quote \family default , \family sans Quotation \family default , or even the \family sans Verse \family default environment in place of the \family sans List \family default environment. The example would have worked exactly the same. \end_layout \begin_layout Subsubsection Example 2: Inheritance \end_layout \begin_layout LyX-Code This is the LyX-Code environment, at level #1, the outermost \end_layout \begin_layout LyX-Code level. Now we will enter \family sans Return \family default , then \begin_inset Info type "shortcut" arg "depth-increment" \end_inset , after \begin_inset Newline newline \end_inset which, we will change to the \family sans Enumerate \family default environment. \end_layout \begin_deeper \begin_layout Enumerate This is the \family sans Enumerate \family default environment, at level #2. \end_layout \begin_layout Enumerate Notice how the nested \family sans Enumerate \family default not only inherits its margins from its parent environment ( \family sans LyX-Code \family default ), but also inherits its font and spacing! \end_layout \end_deeper \begin_layout Standard We ended this example by entering \family sans Return \family default . After that, we needed to reset the paragraph environment to \family sans Standard \family default and reset the nesting depth by using \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset once. \end_layout \begin_layout Subsubsection Example 3: Labels, Levels, and the \family sans Enumerate \family default and \family sans Itemize \family default Environments \begin_inset Argument 1 status collapsed \begin_layout Plain Layout Example #3: Labels, Levels and other list environments \end_layout \end_inset \end_layout \begin_layout Enumerate This is level #1, in an \family sans Enumerate \family default paragraph environment. We're actually going to nest a bunch of these. \end_layout \begin_deeper \begin_layout Enumerate This is level #2. We used \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset followed by \begin_inset Info type "shortcut" arg "depth-increment" \end_inset . Now, what happens if we nest an \family sans Itemize \family default environment inside of this one? It will be at level #3, but what will its label be? An asterisk? \end_layout \begin_deeper \begin_layout Itemize No! It's a bullet. This is the \emph on first \emph default \family sans Itemize \family default environment, even though it's at level #3. So, its label is a bullet. (We got here by using \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset , then \begin_inset Info type "shortcut" arg "depth-increment" \end_inset , then changing the environment to \family sans Itemize \family default .) \end_layout \begin_deeper \begin_layout Itemize Here's level #4, produced using \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset , then \begin_inset Info type "shortcut" arg "depth-increment" \end_inset . We will do that again\SpecialChar ldots \end_layout \begin_deeper \begin_layout Enumerate \SpecialChar ldots to get to level #5. This time, however, we also changed the paragraph environment back to \family sans Enumerate \family default . Notice the type of numbering, it is \emph on lowercase Roman \emph default , because we are in the \emph on thirdfold \emph default \family sans Enumerate \family default environment (that is, it is an \family sans Enumerate \family default inside an \family sans Enumerate \family default inside an \family sans Enumerate \family default ). \end_layout \begin_layout Enumerate What happens if we \emph on don't \emph default change the paragraph environment, but decrease the nesting depth? What type of numbering does \SpecialChar LyX use? \end_layout \begin_layout Enumerate Oh, as if you couldn't guess by now, we're just using \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset to keep the current environment and depth but create a new item. \end_layout \begin_layout Enumerate Let's use \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset to decrease the depth after the next \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset . \end_layout \end_deeper \begin_layout Enumerate This is level #4. Look what type of label \SpecialChar LyX is using! \end_layout \end_deeper \begin_layout Enumerate This is level #3. Even though we've changed levels, \SpecialChar LyX is still using a lowercase Roman numeral as the label.Why? \end_layout \begin_layout Enumerate Because, even though the nesting depth has changed, the paragraph is \emph on still \emph default a thirdfold \family sans Enumerate \family default environment. Notice, however, that \SpecialChar LyX \emph on did \emph default reset the counter for the label. \end_layout \end_deeper \begin_layout Enumerate Another \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset sequence, and we're back to level #2. This time, we not only changed the nesting depth, but we also moved back into the twofold-nested \family sans Enumerate \family default environment. \end_layout \end_deeper \begin_layout Enumerate The same thing happens if we do another \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset sequence and return to level #1, the outermost level. \end_layout \begin_layout Standard Lastly, we reset the environment to \family sans Standard \family default . As you can see, the level number doesn't correspond to what type of labeling \SpecialChar LyX uses for the \family sans Enumerate \family default and \family sans Itemize \family default environments. The number of other \family sans Enumerate \family default environments surrounding it determines what kind of label \SpecialChar LyX uses for an \family sans Enumerate \family default item. The same rule applies for the \family sans Itemize \family default environment, as well. \end_layout \begin_layout Subsubsection Example 4: Going Bonkers \end_layout \begin_layout Enumerate We're going to go totally nuts now. We will not nest as deep as in the other examples, nor will we go into the same detail with how we did it. (level #1: \family sans Enumerate \family default ) \end_layout \begin_deeper \begin_layout Standard ( \family sans Return, \family default \begin_inset Info type "shortcut" arg "depth-increment" \end_inset \family sans , Standard \family default : level #2) We will stick an encapsulated description of how we created the example in parentheses someplace. For example, the two key bindings are how we changed the depth. The environment name is the name of the current environment. Either before or after this, we will put in the level. \end_layout \end_deeper \begin_layout Enumerate ( \family sans Return, Enumerate \family default : level #1) This is the next item in the list. \end_layout \begin_deeper \begin_layout Verse Now we will add verse. \begin_inset Newline newline \end_inset It will get much worse. \begin_inset Newline newline \end_inset ( \family sans Return, \family default \begin_inset Info type "shortcut" arg "depth-increment" \end_inset \family sans , Verse \family default : level #2) \end_layout \begin_layout Verse Fiddle dee, Fiddle doo. \begin_inset Newline newline \end_inset Bippitey boppitey boo! \begin_inset Newline newline \end_inset ( \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset \family sans ) \end_layout \begin_layout Verse Here comes a table: \end_layout \begin_deeper \begin_layout Standard \begin_inset VSpace 0.3cm \end_inset \end_layout \begin_layout Standard \align center \begin_inset Tabular \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none one-fish \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none two-fish \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none red-fish \end_layout \end_inset \begin_inset Text \begin_layout Plain Layout \family roman \series medium \shape up \size normal \emph off \bar no \noun off \color none blue-fish \end_layout \end_inset \end_inset \end_layout \end_deeper \begin_layout Verse ( \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset \family sans , Table, \family default \begin_inset Info type "shortcut" arg "depth-increment" \end_inset 3 times, \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset \family sans , Verse, \begin_inset Newline newline \end_inset \family default \begin_inset Info type "shortcut" arg "depth-decrement" \end_inset ) \end_layout \end_deeper \begin_layout Enumerate ( \family sans Return, Enumerate \family default : level #1) This is another item. Note that selecting a \family sans Table \family default resets the nesting depth to level #1, so we increased the nesting depth 3 times to put the table inside the \family sans Verse \family default environment. \end_layout \begin_layout Quotation We're now ending the \family sans Enumerate \family default list and changing to \family sans Quotation \family default . We're still at level #1. We want to show you some of the things you can do by mixing environments. The next set of paragraphs is a \begin_inset Quotes eld \end_inset quoted letter. \begin_inset Quotes erd \end_inset We will nest both the \family sans Address \family default and \family sans Right \begin_inset space ~ \end_inset Address \family default environments inside of this one, then use another nested \family sans Quotation \family default for the letter body. We will use \begin_inset Info type "shortcut" arg "paragraph-break inverse" \end_inset to preserve the depth. Remember that you need to use \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset to create multiple lines inside the \family sans Address \family default and \family sans Right \begin_inset space ~ \end_inset Address \family default environments.

This inserts a plain separator (red line in \SpecialChar LyX ) and before or behind it the new list. Inside nested environments, it is also possible to split the outer environment. \end_layout \begin_layout Standard By right-clicking on a separator one can change it into a paragraph separator (red arrow in LyX). The difference between both separator types is that the plain separator only splits the list and not the current paragraph. \end_layout \begin_layout Standard In general, you get an environment separator when you press \begin_inset Info type "shortcut" arg "paragraph-break" \end_inset in a \family sans Standard \family default environment immediately after a non-Standard one. \end_layout \begin_layout Section Spacing, pagination and line breaks \begin_inset Index idx status collapsed \begin_layout Plain Layout Spacing \end_layout \end_inset \end_layout \begin_layout Standard What is a space?

Fills \end_layout \end_inset is a variable space, set so that the space is maximal within one page. An example: you have only two short paragraphs on one page with a \family sans Vfill \family default between them. Then the first paragraph is placed at the top of the page and the second one at the bottom, because the space between them is then maximal. \family sans VFill \family default s work like \family sans HFill \family default s: they fill the remaining vertical space on a page with blank space. \begin_inset Foot status collapsed \begin_layout Plain Layout \family sans HFill \family default s are described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Horizontal-Space" \end_inset . \end_layout \end_inset If there are several \family sans VFill \family default s on a page, they divide the remaining vertical space equally between themselves.

The second type, that is inserted via the menu \family sans Insert\SpecialChar menuseparator Formatting\SpecialChar menuseparator Page \begin_inset space ~ \end_inset Break \family default , ends a page but stretches the content of the page, so that it fills out the complete page. This type is useful to avoid whitespace when a page break produces a page on which only the last few lines are absent. \end_layout \begin_layout Standard You might try to use a page break to ensure that a figure or table appears at the top of a page. This is, of course, the wrong way to do it. \SpecialChar LyX gives you a way of automatically ensuring that your figures and tables appear at the top of a page (or the bottom, or on their own page) without having to worry about what precedes or follows your figure or table.

But to achieve a better quality, many fonts define several font sizes. That improves the appearance because you need more details at large font sizes than at small ones. \begin_inset Newline newline \end_inset The font types \family typewriter TrueType \family default , \family typewriter OpenType \family default , and \family typewriter Type \begin_inset space ~ \end_inset 1 \family default are vector fonts. \end_layout \begin_layout Description Bitmap \begin_inset space ~ \end_inset fonts \begin_inset Index idx status collapsed \begin_layout Plain Layout Fonts ! Bitmap- \end_layout \end_inset on the other hand, are defined by bitmap graphics from the start; so they will look good at all the sizes they are meant for. However, they don't scale well, because in order to scale a glyph, each pixel is enlarged into several pixels. It is the same effect that happens if you try to enlarge a picture in an image manipulation program. In order to mitigate this effect, bitmap fonts are typically provided in several fixed sizes typically from around 8 \begin_inset space ~ \end_inset pixels high up to 34 \begin_inset space ~ \end_inset pixels or so high in steps according to what is believed to be useful. The advantage of bitmap fonts is that no complicated computations are necessary to display each glyph; so bitmap fonts display therefore more quickly than scalable fonts. The disadvantage is that sizes that don't exist as fixed versions have to be scaled by doubling pixels, and thus look bad. \begin_inset Newline newline \end_inset Bitmap fonts are named \family typewriter Type \begin_inset space ~ \end_inset 3 \family default in PostScript- and PDF-documents. \end_layout \begin_layout Standard The result of all this is that bitmap fonts are best for the size they are designed for, while scalable fonts are good for nearly all sizes. So one needs fewer font size definitions for scalable fonts. That's the reason why nearly all text rendering and typesetting programs use scalable fonts. \end_layout \begin_layout Standard To see which fonts are used in a PDF-document, look at its document properties. \end_layout \begin_layout Standard Many modern typesetting and markup languages have begun to move towards specifying \change_deleted -712698321 1525757415 character \change_inserted -712698321 1525757415 text \change_unchanged styles rather than specifying a particular font. For example, instead of changing to an italicized version of the current font to emphasize text, you use an \begin_inset Quotes eld \end_inset emphasized style \begin_inset Quotes erd \end_inset instead. This concept fits in perfectly with \SpecialChar LyX . In \SpecialChar LyX , you do things based on contexts, rather than focusing on typesetting details. \end_layout \begin_layout Subsection \SpecialChar LaTeX font support \begin_inset CommandInset label LatexCommand label name "subsec:LaTeX-font-support" \end_inset \end_layout \begin_layout Standard Traditionally, \SpecialChar LaTeX used its own fonts. That is to say, you cannot directly access the fonts installed on your operating system, but you have to use specific fonts provided by your \SpecialChar LaTeX distribution. The reason is that \SpecialChar LaTeX needs some extra information about the fonts, which have to be provided by additional files and packages. The downside of this is that your font choice is somewhat limited compared to a word processor. On the other hand this comes with the advantage that the provided fonts are generally of very good quality, and that \SpecialChar LaTeX files are very portable across different machines. Also, the range of fonts supported by traditional \SpecialChar LaTeX has increased a lot in the meantime; so you can find packages for many free and commercial fonts. \SpecialChar LyX supports the fonts that are under a free license via the user interface (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Document-Font" \end_inset for details). Other fonts are available if you enter the relevant \SpecialChar LaTeX code in the document preamble (please refer to the documentation of your desired font). \end_layout \begin_layout Standard Recent developments brought some new \SpecialChar LaTeX engines that are also able directly to access fonts that are installed for your operating system, namely Xe\SpecialChar TeX and Lua\SpecialChar TeX . Both engines are supported by \SpecialChar LyX . By using them, you can theoretically use any OpenType or TrueType font that is installed on your system. The next section describes how to use these fonts. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default In practice, some fonts might fail due to a legacy (non Unicode) font encoding, bad metrics, or other font deficiencies; so you might have to experiment. \end_layout \end_inset \end_layout \begin_layout Subsection Document Font and Font size \begin_inset CommandInset label LatexCommand label name "subsec:Document-Font" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Font !

In the \family sans Fonts \family default section of the dialog, you can specify which font should be used for the three different font shapes — roman (serif), \family sans sans \begin_inset space ~ \end_inset serif \family default and \family typewriter typewriter \family default (monospaced) — and you can specify the base font size and scaling factors for (some) sans \begin_inset space ~ \end_inset serif and typewriter fonts if this is necessary to fit with the roman font. \end_layout \begin_layout Standard If you select \family sans Use non-TeX fonts \family default , you will have access to the fonts installed on your operating system. This requires that you use \family sans PDF (XeTeX) \family default , \family sans PDF (LuaTeX) \family default or \family sans DVI (LuaTeX) \family default as the output format, i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space \space{} \end_inset you will have to have either Xe\SpecialChar TeX or Lua\SpecialChar TeX installed (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-font-support" \end_inset ). You will then not have access to \SpecialChar TeX 's own fonts. Note that \SpecialChar LyX then lists all available fonts in each of the three lists (roman, sans \begin_inset space ~ \end_inset serif, and typewriter), since \SpecialChar LyX cannot determine the family. Also note that the output might fail with some of the listed fonts, due to the encoding of the fonts and\SpecialChar breakableslash or font failures. \SpecialChar LyX cannot determine this in advance, so you might need to experiment. \end_layout \begin_layout Standard If you use \SpecialChar TeX fonts (which is the default), the possible options for the font include \family sans Default \family default and a list of fonts available with your \SpecialChar LaTeX distribution. If you select \family sans Default, \family default the font that is preset by the current document class is used.

However, some classes set different default fonts. \end_layout \begin_layout Standard As \family typewriter ec \family default is a bitmap font, it looks pixelated in PDF output, especially when you read the PDF in a zoomed size. \begin_inset Foot status collapsed \begin_layout Plain Layout This problem is less severe if you read PDFs in \family typewriter Adobe \begin_inset space ~ \end_inset Reader \family default version 6 or later, because this program includes a special bitmap font renderer. \end_layout \end_inset To get rid of pixelated fonts, you have to use a vector font. Depending on how your document should look, you can either: \end_layout \begin_layout Itemize select the \family sans Latin \begin_inset space ~ \end_inset Modern \family default fonts, which is the recommended choice if you want to keep the look of \family typewriter cm \family default / \family typewriter ec \family default . \family sans Latin \begin_inset space ~ \end_inset Modern \family default was developed for the \SpecialChar LaTeX community in order to replace \family typewriter cm \family default as the default font. It covers a huge range of glyphs and several font shapes. Except for some details, where the appearance was improved, \family sans Latin \begin_inset space ~ \end_inset Modern \family default looks identical to \family typewriter cm \family default . \begin_inset Foot status collapsed \begin_layout Plain Layout One difference is improved kerning. \end_layout \end_inset \end_layout \begin_layout Itemize If you do not like the look of \family typewriter cm \family default / \family typewriter ec \family default , you can of course select one of the other vector fonts provided, e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space ~ \end_inset \family typewriter Times \begin_inset space ~ \end_inset Roman \family default or \family typewriter Palatino \family default .

Its glyphs are thus smaller than glyphs from other fonts in order to fit into the small newspaper columns. Therefore \family sans Times \begin_inset space ~ \end_inset Roman \family default is not the optimal choice for larger documents like books. \end_layout \begin_layout Standard For the font size there are generally four possible values: \family sans Default, 10 \family default , \family sans 11 \family default and \family sans 12 \family default . Some classes provide additional sizes. The size of \family sans Default \family default depends on the class you are using. In the standard classes it is equal to the font size 10. \end_layout \begin_layout Standard Note that the font size is the \emph on base size \emph default . That means that \SpecialChar LyX scales all other possible font sizes (such as those used in footnotes, super-, and subscripts) by this value. You can fine-tune the font size of text parts via the \family sans Text \begin_inset space ~ \end_inset Style \family default dialog if needed. The possible font sizes for text parts are explained in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Fine-Tuning-with-the" \end_inset . \end_layout \begin_layout Standard The \family sans Default \begin_inset space ~ \end_inset Family \family default selection lets you specify whether the base font of your document should be roman, sans \begin_inset space ~ \end_inset serif or typewriter. The \family sans Default \family default selection uses what is preset by the class, the other selections override this. In most cases, \family sans Default \family default is equal to \family sans roman \family default , but some classes (such as presentation classes) use other defaults. \end_layout \begin_layout Standard The \family typewriter \family sans LaTeX font encoding \family default selection is an expert setting which lets you change the value passed to the \SpecialChar LaTeX -package \series bold fontenc \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! fontenc \end_layout \end_inset \change_deleted -712698321 1524413571 (see also section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-settings" \end_inset ) \change_unchanged . Normally, you do not need to change (or even understand) this. Unless you have specific reasons, use \change_deleted -712698321 1524413471 \family sans Default \change_inserted -712698321 1524413474 Automatic \change_unchanged \family default . \end_layout \begin_layout Standard With some fonts, the checkboxes \family sans Use Old Style Figures \family default and \family sans Use True Small Caps \family default are available. These are extra features some fonts provide. If \family sans Use Old Style Figures \family default is checked, old style figures (also known as medieval or text figures) are used. Old style figures are the numerals (0 \begin_inset space \thinspace{} \end_inset – \begin_inset space \thinspace{} \end_inset 9) with ascenders and descenders, which makes them fit nicely with lowercase letters. \family sans Use True Small Caps \family default determines that real small caps are used instead of faked small caps made of scaled capitals. Real small caps are often part of expert font sets; they generally look better than faked small caps but might have to be purchased separately. \end_layout \begin_layout Standard The field \family sans CJK \family default allows users of the languages Chinese, Japanese, Korean (CJK) to specify a font to display the script characters. \begin_inset Foot status collapsed \begin_layout Plain Layout The font will be the argument for the commands of the \SpecialChar LaTeX -package \series bold CJK \series default . \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages !

Also note that some math fonts are sans \begin_inset space ~ \end_inset serif. Your document might therefore look strange when the document text has serifs while the math characters do not. Sans \begin_inset space ~ \end_inset serif math fonts make therefore in most cases only sense if you select \family sans Sans \begin_inset space ~ \end_inset Serif \family default for the \family sans Default \begin_inset space ~ \end_inset family \family default in the document font settings. \end_layout \begin_layout Standard If you use non-\SpecialChar TeX fonts for the document, you can only choose for math to use either the document's class default \SpecialChar TeX font (in most cases \begin_inset Quotes eld \end_inset \family typewriter Computer \begin_inset space ~ \end_inset Modern \family default \begin_inset Quotes erd \end_inset ) or to use the non-\SpecialChar TeX variant of the document's class default font (in most cases \begin_inset Quotes eld \end_inset \family typewriter Latin \begin_inset space ~ \end_inset Modern \family default \begin_inset Quotes erd \end_inset ). \end_layout \begin_layout Subsection Using Different \change_deleted -712698321 1525757119 Character \change_inserted -712698321 1525757120 Text \change_unchanged Styles \change_inserted -712698321 1525595783 \begin_inset CommandInset label LatexCommand label name "subsec:charstyles" \end_inset \change_unchanged \begin_inset Index idx status collapsed \begin_layout Plain Layout Character Styles \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Text Style \end_layout \end_inset \end_layout \begin_layout Standard As we've already seen, \SpecialChar LyX automatically changes the \change_deleted -712698321 1525601052 character \change_unchanged style for certain paragraph environments. \change_inserted -712698321 1525757169 In this section, we will explain how the style of selected text passages can by changed. This is where we meet the concept of \emph on text styles \emph default . \change_deleted -712698321 1525601099 \change_inserted -712698321 1525601099 \end_layout \begin_layout Standard \change_inserted -712698321 1525595930 By default, \change_unchanged \SpecialChar LyX supports two \change_deleted -712698321 1525757160 character \change_inserted -712698321 1525757161 text \change_unchanged styles, \emph on Emphasized \emph default and \noun on Noun \noun default . \change_inserted -712698321 1525757189 These are \emph on builtin \emph default , i. \begin_inset space \thinspace{} \end_inset e., available with all document classes. On top of that, some document classes and modules provide \emph on custom text styles \emph default for specific purposes. We describe both types of text styles in a minute. \end_layout \begin_layout Standard \change_inserted -712698321 1525757201 Before we do that, though, allow us just a few words of what we mean by \emph on text styles \emph default in contrast to \emph on text properties \emph default . Traditional word processors used to focus on so-called \emph on formal markup \emph default : if you wanted to emphasize a word, you selected it and chose e. \begin_inset space \thinspace{} \end_inset g. \begin_inset Quotes eld \end_inset bold style \begin_inset Quotes erd \end_inset — you customized the \emph on text properties \emph default . Modern processors, \SpecialChar LyX among them, encourage the use of \emph on semantic \emph default (or \emph on logical \emph default ) \emph on markup \emph default instead (although formal markup is still possible; see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Fine-Tuning-with-the" \end_inset ). Rather than fiddling with \emph on text properties \emph default , they encourage the use of \emph on text styles \emph default , who are defined with regard to their function (e. \begin_inset space \thinspace{} \end_inset g., \begin_inset Quotes els \end_inset emphasize \begin_inset Quotes ers \end_inset ), not their form ( \begin_inset Quotes els \end_inset bold \begin_inset Quotes ers \end_inset ). There are many advantages of the semantic approach. To begin with, using functional categories keeps you thinking about why you are actually marking up, if your markup is consistent and systematic, and whether this particular markup makes sense. On a more practical level, it is easy to change the appearance if needed. Consider the case when you are writing a paper and set all proper names in \shape smallcaps small caps \shape default via formal markup. Now if the publisher requests to have names appear differently (e. \begin_inset space \thinspace{} \end_inset g., in normal font, or ALL-CAPS), you would have to change any single occurrence. With a semantic markup (such as \noun on noun \noun default ; see below), you'd just need to change the definition of \family sans Noun \family default once and for all. It's a ten second change (if you know how to change the \SpecialChar LaTeX definition). Moreover, semantic markup even allows you to produce different versions of a document, using different markup semantics. \end_layout \begin_layout Standard \change_inserted -712698321 1525757213 With that in mind, we now turn to the semantic text styles that are provided by \SpecialChar LyX . \change_unchanged \end_layout \begin_layout Subsubsection \change_inserted -712698321 1525757220 Builtin Text Styles \begin_inset CommandInset label LatexCommand label name "subsec:Builtin-Character-Styles" \end_inset \end_layout \begin_layout Standard \change_inserted -712698321 1525757226 The two builtin text styles can be \change_deleted -712698321 1525596489 You can \change_unchanged activate \change_inserted -712698321 1525596491 d \change_unchanged \change_deleted -712698321 1525596494 both of these styles \change_unchanged via \change_inserted -712698321 1525596436 the \family sans Text Style \family default dialog, \change_unchanged key bindings \change_deleted -712698321 1525596045 , the menus \change_unchanged , and the toolbar. \end_layout \begin_layout Standard To activate the \family sans Noun \family default style, do one of the following: \end_layout \begin_layout Itemize click on the toolbar button \begin_inset Info type "icon" arg "font-noun" \end_inset \end_layout \begin_layout Itemize use the key binding \begin_inset Info type "shortcut" arg "font-noun" \end_inset \change_inserted -712698321 1525596051 \end_layout \begin_layout Itemize \change_inserted -712698321 1525596318 use the \family sans Text Style \family default dialog ( \begin_inset Info type "menu" arg "dialog-show character" \end_inset or \begin_inset Info type "icon" arg "dialog-show character" \end_inset ) as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Fine-Tuning-with-the" \end_inset \change_unchanged \end_layout \begin_layout Standard These commands are all toggles. That is, if \family sans Noun \family default style is already active, they deactivate it. \end_layout \begin_layout Standard One typically uses the \family sans Noun \family default style for proper names. For example: \begin_inset Quotes eld \end_inset \noun on Matthias Ettrich \noun default is the original author of \SpecialChar LyX . \begin_inset Quotes erd \end_inset \change_inserted -712698321 1525598183 \end_layout \begin_layout Standard \change_inserted -712698321 1525598323 By default, \family sans Noun \family default is producing text in \shape smallcaps Small Caps \shape default , but the definition can be changed. \change_unchanged \end_layout \begin_layout Standard A more widely used \change_deleted -712698321 1525757229 character \change_inserted -712698321 1525757229 text \change_unchanged style is the \family sans Emphasized \family default style. You can activate (or deactivate — it's also a toggle) the \family sans Emphasized \family default style by: \end_layout \begin_layout Itemize clicking on the toolbar button \begin_inset Info type "icon" arg "font-emph" \end_inset \end_layout \begin_layout Itemize using the keybindings \begin_inset Info type "shortcut" arg "font-emph" \end_inset \change_inserted -712698321 1525596078 \end_layout \begin_layout Itemize \change_inserted -712698321 1525596340 use the \family sans Text Style \family default dialog ( \begin_inset Info type "menu" arg "dialog-show character" \end_inset or \begin_inset Info type "icon" arg "dialog-show character" \end_inset ) as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Fine-Tuning-with-the" \end_inset \change_unchanged \end_layout \begin_layout Standard Normally the \family sans Emphasized \family default style is equivalent to an italic font but some document classes or \SpecialChar LaTeX \change_inserted -712698321 1525598370 \change_deleted -712698321 1525598370 - \change_unchanged packages use a different font \change_inserted -712698321 1525598396 , and you can also customize it yourself by changing the \SpecialChar LaTeX definition \change_unchanged . \end_layout \begin_layout Standard We've been using the \family sans Emphasized \family default style all over the place in this document.

The following example shows the difference: \begin_inset Newline newline \end_inset text with serifs \begin_inset Newline newline \end_inset \family sans text without serifs \family default \begin_inset Newline newline \end_inset Serifs facilitate quick and easy reading. These fonts are therefore used as default (named \family sans roman \family default ). \end_layout \begin_layout Itemize \change_deleted -712698321 1525607419 \family sans Sans serif \family default is not recommended for use as a base type. This font type is therefore often only used for headings and short texts.

When a property is marked for toggling in the \family sans Text \begin_inset space ~ \end_inset Style \family default dialog, applying the style to text that already has the property will cause the property to be removed. If you, for example, apply a style with properties A, B and C to text that currently has font properties B, C, F and G, and if B is set to toggle and C is set not to toggle, the text ends up with properties A, C, F and G. \begin_inset Quotes eld \end_inset Never toggled \begin_inset Quotes erd \end_inset and \begin_inset Quotes eld \end_inset always toggled \begin_inset Quotes erd \end_inset mean that you do not control the toggling behavior. For the properties on the left side of the dialog ( \begin_inset Quotes eld \end_inset Family \begin_inset Quotes erd \end_inset etc.), toggling behavior is up to you. If \family sans Toggle \begin_inset space ~ \end_inset all \family default is checked, all of the left side properties are toggled; by default, none of them are. Finally, \begin_inset Quotes eld \end_inset Reset \begin_inset Quotes erd \end_inset is never toggled. If you, for example, set \begin_inset Quotes eld \end_inset Series \begin_inset Quotes erd \end_inset to \begin_inset Quotes eld \end_inset Reset \begin_inset Quotes erd \end_inset and select \family sans Toggle \begin_inset space ~ \end_inset all \family default , then apply the style to bold face text, the text will revert to the default series ( \begin_inset Quotes eld \end_inset Medium \begin_inset Quotes erd \end_inset ), no matter how many times you apply the style. \change_unchanged \end_layout \begin_layout Standard We conclude \change_inserted -712698321 1525607667 this section \change_unchanged with the same warning once again: Do not overuse the fonts! They are, more often than not, a kludge and a bad substitute for good writing. \end_layout \begin_layout Section Printing and Previewing \end_layout \begin_layout Subsection Overview \end_layout \begin_layout Standard Now that we have covered some of the basic features of document preparation using \SpecialChar LyX , you probably want to know how to print out your masterpiece. Before we tell you that, we want to give you a quick explanation of what goes on behind-the-scenes. We cover this information in much greater detail in the \emph on Additional Features \emph default manual as well. \end_layout \begin_layout Standard \SpecialChar LyX uses the program \SpecialChar LaTeX as its backend. \SpecialChar LaTeX is just a macro package for the \SpecialChar TeX typesetting system, but to prevent confusion, we will only refer to \SpecialChar LaTeX . \SpecialChar LyX is what you use to do your actual writing. Then, \SpecialChar LyX calls \SpecialChar LaTeX to turn your writing into printable output. This happens in two stages: \end_layout \begin_layout Enumerate First, \SpecialChar LyX converts your document to a series of text commands for \SpecialChar LaTeX , generating a file with the extension, \begin_inset Quotes eld \end_inset \family typewriter .tex \family default \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Enumerate Next, \SpecialChar LyX calls \SpecialChar LaTeX to use the commands in the \family typewriter .tex \family default file to produce printable output. \end_layout \begin_layout Subsection Output file formats \begin_inset Index idx status collapsed \begin_layout Plain Layout File formats \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Output-file-formats" \end_inset \end_layout \begin_layout Subsubsection Simple text (ASCII) \begin_inset Index idx status collapsed \begin_layout Plain Layout File formats !

It contains your document as plain text following the rules of the \begin_inset Quotes eld \end_inset American Standard Code for Information Interchange \begin_inset Quotes erd \end_inset (ASCII). \end_layout \begin_layout Standard You can export your document to ASCII with the menu \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator Plain \begin_inset space ~ \end_inset text \family default . However, this will not export any externally generated material such as a Bib\SpecialChar TeX bibliography (section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Bibliography-databases" \end_inset ). If your document includes such material, use \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator More \begin_inset space ~ \end_inset Formats \begin_inset space ~ \end_inset & \begin_inset space ~ \end_inset Options \family default and then select \family sans Plain \begin_inset space ~ \end_inset text \begin_inset space ~ \end_inset (ps2ascii) \family default .

If you know \SpecialChar LaTeX , you can use it to find out \SpecialChar LaTeX -Errors or to process it manually with console commands. The \SpecialChar LaTeX -file is automatically created in \SpecialChar LyX 's temporary directory whenever you view or export your document. \end_layout \begin_layout Standard You can export your document as a \SpecialChar LaTeX -file using the menu \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator LaTeX \family default .

It is called \begin_inset Quotes eld \end_inset device-independent \begin_inset Quotes erd \end_inset (DVI), because it is completely portable; you can move them from one machine to another without needing to do any sort of conversion. DVIs are used for quick previews and as a pre-stage for other output formats, like PostScript. \end_layout \begin_layout Standard DVI files do not contain images, they only link to them. So don't forget to deliver the images together with your DVIs. Because the DVI-viewer has to convert the images in the background to make them visible when you scroll the DVI, this can slow down your computer when you view the DVI. So we recommend using PDF for files with many images. \end_layout \begin_layout Standard You can export your document to DVI by the menus \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator DVI \family default or \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator DVI \begin_inset space ~ \end_inset (LuaTeX). \family default The latter option uses the program \family typewriter Lua\SpecialChar TeX \family default . \family typewriter Lua\SpecialChar TeX \family default is an engine that provides direct Unicode support and support for direct font access (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-font-support" \end_inset ). Lua\SpecialChar TeX is still a work in progress, but it might develop into the next standard \SpecialChar TeX processor. \end_layout \begin_layout Subsubsection PostScript \begin_inset Index idx status collapsed \begin_layout Plain Layout File formats ! PostScript \end_layout \end_inset \end_layout \begin_layout Standard This file type has the extension \begin_inset Quotes eld \end_inset \family typewriter .ps \family default \begin_inset Quotes erd \end_inset . PostScript was developed by the company \family typewriter Adobe \family default as a printer language. The file therefore contains commands that the printer uses to print the file. PostScript can be seen as a \begin_inset Quotes eld \end_inset programming language \begin_inset Quotes erd \end_inset ; you can calculate with it and draw diagrams and images. \begin_inset Foot status collapsed \begin_layout Plain Layout If you are interested in learning more about this, have a look at the \SpecialChar LaTeX -package \series bold pstricks \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! pstricks \end_layout \end_inset . \end_layout \end_inset As a result of this, the files are often bigger than PDFs. \end_layout \begin_layout Standard PostScript can only contain images in the format \begin_inset Quotes eld \end_inset Encapsulated PostScript \begin_inset Quotes erd \end_inset (EPS, file extension \begin_inset Quotes eld \end_inset \family typewriter .eps \family default \begin_inset Quotes erd \end_inset ). As \SpecialChar LyX allows you to use any known image format in your document, it has to convert them in the background to EPS. If, for example, you have 50 \begin_inset space ~ \end_inset images in your document, \SpecialChar LyX has to do 50 \begin_inset space ~ \end_inset conversions when you view or export your document the first time. This might slow down your workflow with \SpecialChar LyX . So if you plan to use PostScript, you can insert your images directly as EPS to avoid this problem. \end_layout \begin_layout Standard You can export to PostScript using the menu \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator PostScript \family default . \end_layout \begin_layout Subsubsection PDF \begin_inset Index idx status collapsed \begin_layout Plain Layout File formats !

The \begin_inset Quotes eld \end_inset Portable Document Format \begin_inset Quotes erd \end_inset (PDF) developed by \family typewriter Adobe \family default was derived from PostScript. It is more compressed and it uses fewer commands than PostScript. As the name \begin_inset Quotes eld \end_inset portable \begin_inset Quotes erd \end_inset implies, it can be processed on any computer system and the printed output looks exactly the same. \end_layout \begin_layout Standard PDF can contain images in its own PDF format and in the formats \begin_inset Quotes eld \end_inset Joint Photographic Experts Group \begin_inset Quotes erd \end_inset (JPG, file extension \begin_inset Quotes eld \end_inset \family typewriter .jpg \family default \begin_inset Quotes erd \end_inset or \begin_inset Quotes eld \end_inset \family typewriter .jpeg \family default \begin_inset Quotes erd \end_inset ) and \begin_inset Quotes eld \end_inset Portable Network Graphics \begin_inset Quotes erd \end_inset (PNG, file extension \begin_inset Quotes eld \end_inset \family typewriter .png \family default \begin_inset Quotes erd \end_inset ). You can also use any other image format, because \SpecialChar LyX converts them in the background to one of these formats. But as described in the section about PostScript, the image conversion will slow down your workflow. So we recommend using images in one of the three formats mentioned above. \end_layout \begin_layout Standard You can export your document to PDF via the menu \family sans File\SpecialChar menuseparator Export \family default in different ways: \end_layout \begin_layout Description PDF \begin_inset space ~ \end_inset (pdflatex) This uses the program \family typewriter pdftex \family default which converts your file directly to PDF. \end_layout \begin_layout Description PDF \begin_inset space ~ \end_inset (Lua \family sans TeX \family default ) This uses the program \family typewriter Lua\SpecialChar TeX \family default which converts your file directly to PDF. \family typewriter Lua\SpecialChar TeX \family default is a new engine, derived from \family typewriter pdflatex \family default , that also provides direct Unicode support and support for direct font access (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-font-support" \end_inset ). Lua\SpecialChar TeX is still a work in progress, but it might develop into the next standard \SpecialChar TeX processor. \end_layout \begin_layout Description PDF \begin_inset space ~ \end_inset (Xe \family sans TeX \family default ) This uses the program \family typewriter Xe\SpecialChar TeX \family default that converts your file directly to PDF. \family typewriter Xe\SpecialChar TeX \family default is a new engine that provides direct Unicode support and support for direct font access (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-font-support" \end_inset ). It is particularly good at typesetting different scripts, for example, vertically written Japanese. \end_layout \begin_layout Description PDF \begin_inset space ~ \end_inset (cropped) This is the same as \family sans PDF \begin_inset space ~ \end_inset (pdflatex) \family default but the result is a PDF with cropped page margins. This is for example useful if you want to use \SpecialChar LyX to generate good-looking formulas to use them in other programs like for presentations. \end_layout \begin_layout Description PDF \begin_inset space ~ \end_inset (dvipdfm) This uses the program \family typewriter dvipdfm \family default that converts your file in the background to DVI and in a second step to PDF. \end_layout \begin_layout Description PDF \begin_inset space ~ \end_inset (ps2pdf) This uses the program \family typewriter ps2pdf \family default that creates a PDF from a PostScript-version of your file. The PostScript-version is produced by the program \family typewriter dvips \family default which uses a DVI-version as intermediate step. So this export variant consists of three conversions. \end_layout \begin_layout Standard We recommend using \family sans PDF \begin_inset space ~ \end_inset (pdflatex) \family default because \family typewriter pdftex \family default supports all the features of actual PDF-versions, is quick, stable, and works without problems. If you rely on multiscript support and\SpecialChar breakableslash or specific OpenType fonts, you might want to try out \family sans PDF \begin_inset space ~ \end_inset (XeTeX) \family default or \family sans PDF \begin_inset space ~ \end_inset (LuaTeX) \family default instead, bearing in mind that these two programs are not yet as mature as \family typewriter pdflatex \family default . \end_layout \begin_layout Subsubsection XHTML \begin_inset Index idx status collapsed \begin_layout Plain Layout FileFormats !

An unintended consequence of these changes was that all dashes were output as non-breakable dashes.

If \SpecialChar LaTeX cannot break a word correctly, you can set hyphenation points manually.

These extra hyphenation points are only recommendations to \SpecialChar LaTeX .

If a \begin_inset Quotes eld \end_inset \family typewriter . \family default \begin_inset Quotes erd \end_inset is at the end of a lowercase letter, it's the end of a sentence; if it's at the end of a capitalized letter, it's an abbreviation. \end_layout \begin_layout Standard Here are some examples of \emph on correct \emph default abbreviations and of the end of a sentence: \end_layout \begin_layout Itemize M.

It can \begin_inset Quotes eld \end_inset float \begin_inset Quotes erd \end_inset forward or backward a page or two, to wherever it fits best. \family sans Footnotes \family default and \family sans Margin \begin_inset space ~ \end_inset Notes \family default are also floats, because they can float to the next page when there are too many notes on the current page. \end_layout \begin_layout Standard Floats make it possible to get a high quality layout. Images and tables can be distributed evenly over the pages to avoid whitespace and pages without text. As the floating often destroys the spatial context between the text and the image/table, every float can be referenced in the text. Floats are therefore numbered. Referencing is described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Cross-References" \end_inset . \end_layout \begin_layout Standard To insert a float, use the menu \family sans Insert\SpecialChar menuseparator Float \family default . A box with a caption will be inserted into your document. The label will automatically be translated to the document language in the output. After the label you can insert the caption text. \begin_inset Index idx status collapsed \begin_layout Plain Layout Floats ! Captions \end_layout \end_inset The image or table is inserted above or below the caption in a separate paragraph within the float. To keep your \SpecialChar LyX -document readable, you can open and close the float box by left-clicking on the box label. A closed float box looks like this: \begin_inset Graphics filename clipart/float.png scale 80 \end_inset – a gray button with a red label. \end_layout \begin_layout Standard You should insert floats in a separate paragraph to avoid possible \SpecialChar LaTeX -errors that can occur when the surrounding text is specially formatted. \end_layout \begin_layout Subsection Figure Floats \begin_inset CommandInset label LatexCommand label name "subsec:Figure-Floats" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Floats !

It is important to use cross-references to figure floats rather than using vague references like \begin_inset Quotes eld \end_inset the figure above \begin_inset Quotes erd \end_inset , because, as \SpecialChar LaTeX will reposition the floats in the final document, it might not be \begin_inset Quotes eld \end_inset above \begin_inset Quotes erd \end_inset at all. For more about cross-references, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Cross-References" \end_inset . \end_layout \begin_layout Standard Normally only one image is inserted in a figure float, but sometimes you might want to use two images with separate subcaptions. This can be done by inserting image floats into existing image floats. Note that only the main caption of the float is added to the List of Figures as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:List-of-Figures" \end_inset .

There you will also find tips and tricks for special cases. \end_layout \begin_layout Section Basic Math Editing \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Basics \end_layout \end_inset \end_layout \begin_layout Standard To create a math formula, you can just click on the toolbar icon \begin_inset Info type "icon" arg "math-mode on" \end_inset (shortcut \begin_inset Info type "shortcut" arg "math-mode" \end_inset ). That will create a little blue rectangle, with purple markers around its corners. That blue rectangle is the formula itself; the purple markers indicate what level of nesting within the formula you are at. You can also choose a particular formula type to insert via the \family sans Insert\SpecialChar menuseparator Math \family default menu. \end_layout \begin_layout Standard Editing the parameters of a formula and adding math constructs can be done with the \family sans math \begin_inset space ~ \end_inset toolbar \family default , that appears if the cursor is in a formula. \end_layout \begin_layout Standard There are two main types of formulas, inline formulas and display formulas. Inline formulas appear within a text line, like this one: \end_layout \begin_layout Standard This is a line with an inline formula \begin_inset Formula $A=B$ \end_inset in it. \end_layout \begin_layout Standard Displayed formulas appear outside the text like if they were in a separate paragraph, like this one: \begin_inset Formula \[ A=B \] \end_inset You can only number and reference displayed formulas. \end_layout \begin_layout Standard \SpecialChar LyX also supports many \SpecialChar LaTeX math commands. For example, typing \begin_inset Quotes eld \end_inset \series bold \backslash alpha \series default \begin_inset Quotes erd \end_inset , followed by a space, in a formula will create the Greek letter \begin_inset Formula $\alpha$ \end_inset . Typing commands might sometimes be faster than using the \family sans Math \begin_inset space ~ \end_inset Panel \family default . \end_layout \begin_layout Subsection Navigating in Formulas \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Navigating \end_layout \end_inset \end_layout \begin_layout Standard The best control over the cursor position within an existing formula is achieved with the arrow keys. \SpecialChar LyX uses small rectangles to indicate places where something can be inserted. The arrow keys can be used to navigate between parts of a formula. Pressing \family sans Space \family default will leave a formula construct (a square root \begin_inset Formula $\sqrt{2}$ \end_inset , or parentheses \begin_inset Formula $\left(f\right)$ \end_inset , or a matrix \begin_inset Formula $\left[\begin{array}{cc} 1 & 2\\ 3 & 4 \end{array}\right]$ \end_inset ). Pressing \family sans Escape \family default will leave the formula, placing the cursor after the formula. \family sans Tab \family default can be used to move horizontally in a formula; for example, through the cells of a matrix or the positions in a multi-line equation. \end_layout \begin_layout Standard \family sans Space \family default , printed in this document as \begin_inset Quotes eld \end_inset \begin_inset space \textvisiblespace{} \end_inset \begin_inset Quotes erd \end_inset , seems to do nothing in a formula, since it does not add a space between characters, but it does exit a nested structure. For this reason, you have to be careful about using \family sans Space \family default . For example, if you want \begin_inset Formula $\sqrt{2x+1}$ \end_inset , type \series bold \backslash sqrt \begin_inset space \textvisiblespace{} \end_inset 2x+1 \series default and not \series bold \backslash sqrt \begin_inset space \textvisiblespace{} \end_inset 2x \begin_inset space \textvisiblespace{} \end_inset +1 \series default , since in the latter case only the \family typewriter \begin_inset Formula $2x$ \end_inset \family default will be under the square root sign: \begin_inset Formula $\sqrt{2x}+1$ \end_inset . \end_layout \begin_layout Standard You can leave many parts of a formula, like this matrix, partially filled in, such as: \begin_inset Formula \[ \left(\begin{array}{ccc} \lambda_{1}\\ & \ddots\\ & & \lambda_{n} \end{array}\right) \] \end_inset If you leave a fraction only partially filled in, or a subscript with nothing in it, the results will be unpredictable, but most constructs don't mind. \end_layout \begin_layout Subsection Selecting Text \end_layout \begin_layout Standard You can select text within a formula in two different ways. Place the cursor at one end of the string of text you want, and press \family sans Shift \family default and a cursor movement key to select text. It will be highlighted as with regular text selection. Alternatively, you can select text with the mouse in the usual way. That text can then be cut or copied, and then pasted within any formula, but not in a normal text region in \SpecialChar LyX . \end_layout \begin_layout Subsection Exponents and Subscripts \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Exponents \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Subscripts \end_layout \end_inset \end_layout \begin_layout Standard You can use the math panel to add super- or subscripts (buttons \begin_inset Info type "icon" arg "math-superscript" \end_inset and \begin_inset Info type "icon" arg "math-subscript" \end_inset ), but it is often much easier to use a command. To get \begin_inset Formula $x^{2}$ \end_inset , type in a formula \series bold x^2 \begin_inset space \textvisiblespace{} \end_inset \series default . The final \family sans Space \family default puts the cursor back down on the base line of the expression. If you type \series bold x^2y \series default , you will get \begin_inset Formula $x^{2y}$ \end_inset , to get \begin_inset Formula $x^{2}y$ \end_inset , type \series bold x^2 \begin_inset space \textvisiblespace{} \end_inset y \series default . If you use characters in the superscript, that could be accented with the circumflex \begin_inset Quotes eld \end_inset ^ \begin_inset Quotes erd \end_inset , you have to use an extra \family sans Space \family default to separate the circumflex and the character. For example, if you want \begin_inset Formula $x^{a}$ \end_inset , type \series bold x^ \begin_inset space \textvisiblespace{} \end_inset a \series default . Subscripts are similar: To get \begin_inset Formula $a_{1}$ \end_inset , type \series bold a_1 \begin_inset space \textvisiblespace{} \end_inset \series default . \end_layout \begin_layout Subsection Fractions \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Fractions \end_layout \end_inset \end_layout \begin_layout Standard Create a fraction either with the command \series bold \backslash frac \series default or by using the icon \begin_inset Info type "icon" arg "math-insert \\frac" \end_inset in the \family sans Math \begin_inset space ~ \end_inset Panel \family default . You will be presented with an empty fraction. The cursor is above the fraction line. To move it to the bottom, simply press \family sans Down \family default . To move back up, press \family sans Up \family default . Any math structure can be placed in a fraction, as this example shows: \begin_inset Formula \[ \left[\frac{1}{\left(\begin{array}{cc} 2 & 3\\ 4 & 5 \end{array}\right)}\right] \] \end_inset \end_layout \begin_layout Subsection Roots \begin_inset Index idx status collapsed \begin_layout Plain Layout Math !

With the command \series bold \backslash root \series default you can produce roots of higher orders, like cube roots, while \series bold \backslash sqrt \series default always produces a square root. \end_layout \begin_layout Subsection Operators with Limits \begin_inset Index idx status collapsed \begin_layout Plain Layout Math !

Integrals \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Operators-with-Limits" \end_inset \end_layout \begin_layout Standard Sum ( \begin_inset Formula $\sum$ \end_inset ) and integral ( \begin_inset Formula $\int$ \end_inset ) operators are very often decorated with limits. These limits can be entered in \SpecialChar LyX by entering them as you would enter a super- or subscript, directly after the symbol. The sum operator will automatically place its \begin_inset Quotes eld \end_inset limits \begin_inset Quotes erd \end_inset over and under the symbol in displayed formulas, and to the side in inline formulas, as in \begin_inset Formula $\sum_{n=0}^{\infty}\frac{1}{n!}=e$ \end_inset , versus \begin_inset Formula \[ \sum_{n=0}^{\infty}\frac{1}{n!}=e \] \end_inset Integral signs, however, will place the limits to the side in both formula types. \end_layout \begin_layout Standard All operators with limits will be automatically re-sized when placed in display mode. The placement of the limits can be changed by placing the cursor directly behind the operator and using the menu \family sans Edit\SpecialChar menuseparator Math\SpecialChar menuseparator Change \begin_inset space ~ \end_inset Limits \begin_inset space ~ \end_inset Type \family default or entering \begin_inset Info type "shortcut" arg "math-limits" \end_inset . \end_layout \begin_layout Standard Certain other mathematical expressions also have this \begin_inset Quotes eld \end_inset moving limits \begin_inset Quotes erd \end_inset feature, such as \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Limits \end_layout \end_inset \begin_inset Formula \[ \lim_{x\rightarrow\infty}f(x), \] \end_inset which will place the \begin_inset Formula $x\rightarrow\infty$ \end_inset underneath the \begin_inset Quotes eld \end_inset lim \begin_inset Quotes erd \end_inset in display mode. In inline formulas it looks like this: \begin_inset Formula $\lim_{x\rightarrow\infty}f(x)$ \end_inset . \end_layout \begin_layout Standard Note that the lim-function was entered as the function macro \series bold \backslash lim \series default . Have a look at section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Functions" \end_inset for an explanation of function macros. \end_layout \begin_layout Subsection Math Symbols \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Symbols \end_layout \end_inset \end_layout \begin_layout Standard Most math symbols can be found in the \family sans Math \begin_inset space ~ \end_inset Panel \family default under one of several categories; including \family sans Greek \family default , \family sans Operators \family default , \family sans Relations \family default , \family sans Arrows \family default . There are also the additional symbols provided by the American Mathematical Society (AMS). \end_layout \begin_layout Standard If you know the \SpecialChar LaTeX -command for a construct or symbol you wish to use, you don't have to use the \family sans Math \begin_inset space ~ \end_inset Panel \family default ; you can type the command directly into the formula. \SpecialChar LyX will convert it to the corresponding symbol or construct. \end_layout \begin_layout Subsection Altering Spacing \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Spaces \end_layout \end_inset \end_layout \begin_layout Standard You may want to create spaces that differ from the standard spacing that \SpecialChar LaTeX provides. To do this, press \begin_inset Info type "shortcut" arg "command-alternatives math-space ; space-insert protected" \end_inset or use the \family sans Math \begin_inset space ~ \end_inset Panel \family default button \begin_inset Info type "icon" arg "math-insert \\space" \end_inset . This generates a small space, and shows a small marker on the screen. For example, the sequence \series bold a Ctrl+Space b \series default : \begin_inset Formula $a\,b$ \end_inset appears in \SpecialChar LyX as \begin_inset Graphics filename clipart/SpaceMarker.png \end_inset . You can change the space to different sizes when you set the cursor behind the space marker and enter space again several times. With every space enter the size will be changed. Some markers for the space size appear red in \SpecialChar LyX , because they are negative spaces. Here are two examples: \end_layout \begin_layout Standard \series bold a Ctrl+Space b \series default and 3× \family sans Space \family default : \begin_inset Formula $a\quad b$ \end_inset \end_layout \begin_layout Standard \series bold a Ctrl+Space b \series default and 5× \family sans Space \family default : \begin_inset Formula $a\!b$ \end_inset \end_layout \begin_layout Subsection Functions \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Functions \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Functions" \end_inset \end_layout \begin_layout Standard The \family sans Math \begin_inset space ~ \end_inset Panel \family default contains under the button \begin_inset Info type "icon" arg "math-insert \\functions" \end_inset a number of function macros, such as \begin_inset Formula $\sin$ \end_inset , \begin_inset Formula $\lim$ \end_inset , \emph on etc \emph default . (you can also insert them in a formula by typing \series bold \backslash sin \series default etc.). Standard mathematical practice is that functions are printed upright to avoid confusions, because \begin_inset Formula $sin$ \end_inset does normally mean \begin_inset Formula $s\cdot i\cdot n$ \end_inset . \end_layout \begin_layout Standard Using the function macros will also produce correct spacing around the function: \begin_inset Formula $a\sin x$ \end_inset is different from \begin_inset Formula $asinx$ \end_inset . \end_layout \begin_layout Standard For some mathematical objects, like limits, the macro changes where subscripts are placed, as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Operators-with-Limits" \end_inset . \end_layout \begin_layout Subsection Accents \begin_inset Index idx status collapsed \begin_layout Plain Layout Math ! Accents \end_layout \end_inset \end_layout \begin_layout Standard In a formula you can insert accented characters in the same way as in text mode. This may depend on your keyboard, or the bindings file you use. You can also use \SpecialChar LaTeX commands, for example, to enter \begin_inset Formula $\hat{a}$ \end_inset even if your keyboard doesn't have the circumflex enabled. Our example is entered by typing \series bold \backslash hat \begin_inset space \textvisiblespace{} \end_inset a \series default in a formula.

For some purposes, using just the keys \family typewriter []{}()|<> \family default should suffice. But if you want to surround a large structure, like a matrix or a fraction, or if you have several layers of brackets, it is better to use the math toolbar delimiter icon \begin_inset Info type "icon" arg "dialog-show mathdelimiter" \end_inset . For example, if you construct the brackets around a matrix in this way: \begin_inset Formula \[ \left[\begin{array}{cc} 1 & 2\\ 3 & 4 \end{array}\right] \] \end_inset it makes it easier to see the layers of parentheses. Below, the expression on the left was entered using the delimiter icon \begin_inset Info type "icon" arg "dialog-show mathdelimiter" \end_inset and the expression on the right was entered using the \family typewriter () \family default keys. \begin_inset Formula \[ \frac{1}{\left(1+\left(\frac{1}{1+\left(\frac{1}{1+x}\right)}\right)\right)}\qquad\qquad\frac{1}{(1+(\frac{1}{1+(\frac{1}{1+x})}))} \] \end_inset \end_layout \begin_layout Standard If you use the delimiter icon, the parentheses, and other brackets from that menu will automatically re-size to accommodate the size of what is inside. \end_layout \begin_layout Standard To construct brackets click on the button for the bracket you want on the left side and right side. If you use the option \family sans Keep \begin_inset space ~ \end_inset matched \family default , the selected bracket type will be used for the left and the right side.

Then choose the appropriate brackets for left and right and click on \family sans Insert \family default . The most common bracket combinations (parentheses, square brackets, and braces, on both sides) can be entered more quickly using keyboard shortcuts.

Here is an example: \begin_inset Formula \[ \left(\begin{array}{ccc} 1 & 2 & 3\\ 4 & 5 & 6\\ 7 & 8 & 9 \end{array}\right) \] \end_inset The parentheses aren't automatic, but you can add them as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Brackets-and-Delimiters" \end_inset . When you construct the matrix, you can decide whether the column entries will be left-, right-, or center-justified. This alignment is set in the box \family sans Horizontal \family default with the letters \begin_inset Quotes eld \end_inset \family sans l \family default \begin_inset Quotes erd \end_inset , \begin_inset Quotes eld \end_inset \family sans r \family default \begin_inset Quotes erd \end_inset , and \begin_inset Quotes eld \end_inset \family sans c \family default \begin_inset Quotes erd \end_inset . \SpecialChar LyX proposes a \begin_inset Quotes eld \end_inset \family sans c \family default \begin_inset Quotes erd \end_inset for every column as default. For example, the sequence \begin_inset Quotes eld \end_inset \family sans lcr \family default \begin_inset Quotes erd \end_inset means that the first column will be left-justified, the second will be centered, and the third column will be right-justified, because each letter corresponds to the relevant column. The result will look like this: \begin_inset Formula \[ \begin{array}{lcr} this & this\,column & this\,column\\ column & has & has\,right\\ has\,left\,alignment & center\,alignment & alignment \end{array}. \] \end_inset \end_layout \begin_layout Standard You can add more rows to an existing matrix by entering \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset while the cursor is in the matrix. Adding or deleting columns can be done via the menu \family sans Edit\SpecialChar menuseparator Math \family default or the math toolbar. \end_layout \begin_layout Standard There are other arrays used in formulas, such as distinctions of cases.

In an empty formula you can see that three blue boxes appear, one for each column. When you press \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset in a non-empty formula, the part before the relation sign (equal sign \begin_inset Quotes eld \end_inset = \begin_inset Quotes erd \end_inset etc.) will be inserted automatically in the first column, the relation sign is in the second column, and the rest in the third column. A new row is created by every further entry of \begin_inset Info type "shortcut" arg "newline-insert newline" \end_inset . Multi-line formulas are always displayed formulas. Here is an example: \begin_inset Formula \begin{eqnarray} a^{2} & = & (b^{2}+c^{2})(b^{2}-c^{2})\nonumber \\ a & = & \sqrt{b^{4}-c^{4}}\label{eq:asquared} \end{eqnarray} \end_inset Note that the middle column is designed for relation signs so structures in this column will be printed in a smaller size: \begin_inset Formula \begin{eqnarray*} \frac{A}{B} & \frac{A}{B} & \frac{A}{B} \end{eqnarray*} \end_inset \end_layout \begin_layout Standard The multi-line formula type described here is called \family typewriter \series medium eqnarray \family default \series default .

The formula number appears in \SpecialChar LyX within parentheses. The number shown is temporary and may be different when the output is generated. The placement and format of the formula number in the output depends on the document class. In this document the number is printed together with the chapter number, separated by a dot: \begin_inset Formula \begin{equation} 1+1=2 \end{equation} \end_inset Using \begin_inset Info type "shortcut" arg "math-number-toggle" \end_inset in a numbered formula will switch off the numbering.

A label is inserted with the menu \family sans Insert\SpecialChar menuseparator Label \family default (toolbar button \begin_inset Info type "icon" arg "label-insert" \end_inset ) when the cursor is in the formula. This opens a dialog to enter the label. It is recommended that you use the suggested \begin_inset Quotes eld \end_inset \family sans eq: \family default \begin_inset Quotes erd \end_inset as the first part of the label, because this helps later to identify the label type when you have many labels in your document. We inserted in the following example the label \begin_inset Quotes eld \end_inset eq:tanhExp \begin_inset Quotes erd \end_inset in the second line: \begin_inset Formula \begin{eqnarray} \tanh(x) & = & \frac{\sinh(x)}{\cosh(x)}\nonumber \\ & = & \frac{\mathrm{e}^{2x}-1}{\mathrm{e}^{2x}+1}\label{eq:tanhExp} \end{eqnarray} \end_inset Every labeled line is automatically numbered. Therefore the label is shown behind the formula number. You can reference a labeled formula using the menu \family sans Insert\SpecialChar menuseparator Cross \begin_inset space ~ \end_inset Reference \family default (toolbar button \begin_inset Info type "icon" arg "dialog-show-new-inset ref" \end_inset ). A dialog appears to choose a label you want to refer to.

Every character in this box will be printed in this typeface. Pressing \family sans Space \family default within the box will set the cursor outside, so that you have to use a protected space when you need a space in the box. Here is an example where \begin_inset Quotes eld \end_inset N \begin_inset Quotes erd \end_inset in \family sans Blackboard \family default denotes the set of numbers: \begin_inset Formula \[ f(x)=\sqrt{x}\:;\:x\in\mathbb{N} \] \end_inset \end_layout \begin_layout Standard The typefaces are nestable, which can cause confusion.

Font sizes \end_layout \end_inset \end_layout \begin_layout Standard There are four font styles (relative sizes) used in math-mode, which are automatically chosen in most situations. These are called \family sans textstyle \family default , \family sans displaystyle \family default , \family sans scriptstyle \family default , and \family sans scriptscriptstyle \family default . For most characters, \family sans textstyle \family default and \family sans displaystyle \family default are actually the same size, but fractions, superscripts and subscripts, and certain other structures, are set larger in \family sans displaystyle \family default . Except for some operators, which resize themselves to accommodate various situations, all text will be set in the styles that \SpecialChar LaTeX thinks are appropriate. These choices can be overridden by using the math panel button \begin_inset Info type "icon" arg "math-insert \\style" \end_inset . A box for the size will be created in which you can insert the math structure. For example, you can set \begin_inset Formula $\frac{1}{2}$ \end_inset , which is normally in \family sans textstyle \family default , larger in \family sans displaystyle \family default : \begin_inset Formula ${\displaystyle \frac{1}{2}}$ \end_inset . The four styles are used in the following example: \end_layout \begin_layout Standard \begin_inset Formula $displaystyle$ \end_inset , \begin_inset Formula ${\textstyle textstyle}$ \end_inset , \begin_inset Formula ${\scriptstyle scriptstyle}$ \end_inset , \begin_inset Formula ${\scriptscriptstyle scriptscriptstyle}$ \end_inset . \end_layout \begin_layout Standard All these math-mode font sizes are relative so that if the whole math inset is set in a particular size with the menu \family sans Edit\SpecialChar menuseparator Text \begin_inset space ~ \end_inset Style \family default , all sizes in the formula will be adjusted relative to this size. Similarly, if the base font size of the document is changed, all fonts will be adjusted to correspond. As an example here is a formula in the font size \begin_inset Quotes eld \end_inset largest \begin_inset Quotes erd \end_inset : \end_layout \begin_layout Standard \family roman \size largest \begin_inset Formula $\mathrm{e}=\sum_{n=0}^{\infty}\frac{1}{n!}$ \end_inset \end_layout \begin_layout Section AMS-\SpecialChar LaTeX \begin_inset Index idx status collapsed \begin_layout Plain Layout AMS math \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Math !

You can reference every section, float, footnote, formula, and list in the document. To reference a document part, you have to insert a label into it. The label is used as an anchor and a name for the reference. We want for example to refer to the second item of the following list: \end_layout \begin_layout Enumerate First item \end_layout \begin_layout Enumerate \begin_inset CommandInset label LatexCommand label name "enu:Second-item" \end_inset Second item \end_layout \begin_layout Enumerate Third item \end_layout \begin_layout Standard First we insert a label into the second item with the menu \family sans Insert\SpecialChar menuseparator Label \family default or by pressing the toolbar button \begin_inset Info type "icon" arg "label-insert" \end_inset . A gray label box like this: \begin_inset Graphics filename clipart/label.png \end_inset is inserted and the label window pops up asking for the label text. \SpecialChar LyX offers as text the first words of the item with a prefix, in our case the text \begin_inset Quotes eld \end_inset \family sans enu:Second-item \family default \begin_inset Quotes erd \end_inset . The prefix \begin_inset Quotes eld \end_inset \family sans enu: \family default \begin_inset Quotes erd \end_inset stands for \begin_inset Quotes eld \end_inset enumerate \begin_inset Quotes erd \end_inset . The prefix depends on the document part where the label is inserted; for example, if you insert a label into a section heading, the suggested prefix will be \begin_inset Quotes eld \end_inset \family sans sec: \family default \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Standard To reference the item, we refer to its label using the menu \family sans Insert\SpecialChar menuseparator Cross-Reference \family default or the toolbar button \begin_inset Info type "icon" arg "dialog-show-new-inset ref" \end_inset . A gray cross-reference box like this: \begin_inset Graphics filename clipart/reference.png \end_inset is inserted and the cross-reference window appears showing all the labels in the document. We can now sort the labels alphabetically and then choose the entry \begin_inset Quotes eld \end_inset \family sans enu:Second-item \family default \begin_inset Quotes erd \end_inset . At the position of the cross-reference box the item number will appear in the output. \end_layout \begin_layout Standard As an alternative to \family sans Insert\SpecialChar menuseparator Cross-Reference \family default , you can right-click on a label and in the popup menu select \family sans Copy as Reference \family default . The cross-reference to this label is now in the clipboard and can be pasted to the actual cursor position via the menu \family sans Edit\SpecialChar menuseparator Paste \family default (shortcut \begin_inset Info type "shortcut" arg "paste" \end_inset ). \end_layout \begin_layout Standard Here is our cross-reference: Item \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "enu:Second-item" \end_inset \end_layout \begin_layout Standard It is recommended to use a protected space \begin_inset Foot status collapsed \begin_layout Plain Layout described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Protected-Space" \end_inset \end_layout \end_inset between the cross-reference name and the cross-reference to avoid ugly line breaks between them. \end_layout \begin_layout Standard There are eight formats of cross-references: \end_layout \begin_layout Description : prints the number, this is the default: \begin_inset CommandInset ref LatexCommand ref reference "fig:Two-images" \end_inset \end_layout \begin_layout Description (): prints the number within two parentheses, this is the style normally used to reference formulas, especially when the reference name \begin_inset Quotes eld \end_inset Equation \begin_inset Quotes erd \end_inset is omitted: \begin_inset CommandInset ref LatexCommand eqref reference "eq:tanhExp" \end_inset \end_layout \begin_layout Description : prints the page number: Page \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand pageref reference "fig:Two-images" \end_inset \end_layout \begin_layout Description on \begin_inset space ~ \end_inset page \begin_inset space ~ \end_inset : prints the text “on page” and the page number: \begin_inset CommandInset ref LatexCommand vpageref reference "fig:Two-images" \end_inset \begin_inset Newline newline \end_inset If the label is on the same page, it prints “on this page”; if the label is on a facing page in a two-sided document, it prints “on the facing page”; if it is on the previous page which is not a facing page, it prints “on the previous page”; if it is on the next page which is not a facing page, it prints “on the next page”. The wording of the printed text also depends on the used document class. \end_layout \begin_layout Description \begin_inset space ~ \end_inset on \begin_inset space ~ \end_inset page \begin_inset space ~ \end_inset : prints the number, the text “on page” and the page number: \begin_inset CommandInset ref LatexCommand vref reference "fig:Two-images" \end_inset \begin_inset Newline newline \end_inset If the label is on the same page, this format behaves like \family sans \series bold \family default \series default ; otherwise it behaves like \family sans \series bold on \begin_inset space ~ \end_inset page \begin_inset space ~ \end_inset \family default \series default . \end_layout \begin_layout Description Formatted \begin_inset space ~ \end_inset reference: prints a self defined cross-reference format. \begin_inset Newline newline \end_inset \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default This feature is only available when you have the \SpecialChar LaTeX -package \series bold prettyref \series default or \series bold refstyle \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! prettyref \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! refstyle \end_layout \end_inset installed. \end_layout \end_inset \begin_inset Newline newline \end_inset You can select which \SpecialChar LaTeX -package should be used for this feature by setting the option \family sans Use refstyle (not prettyref) for cross-references \family default in the menu \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Document Class \family default . The package \series bold refstyle \series default is the default and preferred because \series bold prettyref \series default supports only English documents. The format is specified by using the command \series bold \backslash newrefformat \series default (prettyref) or \series bold \backslash newref \series default (refstyle) in the \SpecialChar LaTeX preamble of the document. For example redefining all references to figures (which have the label shortcut \begin_inset Quotes eld \end_inset \family sans fig \family default \begin_inset Quotes erd \end_inset ) can be done for \series bold refstyle \series default with this command: \begin_inset Newline newline \end_inset \series bold \backslash newref{fig}{refcmd={Image on page \backslash pageref{#1}}} \series default \begin_inset Newline newline \end_inset Note that neither \series bold prettyref \series default nor \series bold refstyle \series default predefines reference formats for all available types. This is especially true for the wide variety of mathematical `theorem' environments. So if you want to make formatted references to, say, Propositions, then you will need to define the relevant format yourself. For \series bold prettyref \series default , you might do so as follows: \begin_inset Newline newline \end_inset \series bold \backslash newrefformat{prop}{Proposition \backslash ref{#1}} \series default \begin_inset Newline newline \end_inset For more information about defining formatted references, have a look at the package documentation \begin_inset CommandInset citation LatexCommand cite key "prettyref,refstyle" literal "true" \end_inset . \begin_inset Newline newline \end_inset The options \family sans Plural \family default and \family sans Capitalized \family default will be available with formatted references only if you are using the \series bold refstyle \series default package. \end_layout \begin_layout Description Textual \begin_inset space ~ \end_inset reference: prints the caption or the name of the reference: \begin_inset CommandInset ref LatexCommand nameref reference "fig:Two-images" \end_inset \end_layout \begin_layout Description Label \begin_inset space ~ \end_inset only: prints only the \SpecialChar LaTeX label for the reference: \begin_inset CommandInset ref LatexCommand labelonly reference "fig:Two-images" \end_inset \begin_inset Newline newline \end_inset This allows for customization, using \SpecialChar TeX Code, if you want to issue a command that \SpecialChar LyX does not support. If you are using \series bold refstyle \series default , then you may want to use the \family sans No \begin_inset space ~ \end_inset Prefix \family default option, which will output only the part of the reference following the \begin_inset Quotes eld \end_inset : \begin_inset Quotes erd \end_inset separator. This is the form needed for e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset \series bold refstyle \series default 's range commands.The number and current page of the referenced document part in the output is automatically calculated by \SpecialChar LaTeX . The varieties are adjusted in the field \family sans Format \family default of the cross-reference window, that appears when you click on the cross-referen ce. \end_layout \begin_layout Standard You can only use the style \family sans \family default to reference numbered document parts, while the reference style \family sans \family default is always possible. \end_layout \begin_layout Standard If you want to reference a section, put the label in the section heading; for floats put the label in the caption; for footnotes put the label in it. Referencing formulas is explained in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Formula-Numbering-and" \end_inset . \end_layout \begin_layout Standard Right-clicking on a cross-reference opens a context menu. The entry \family sans Go \begin_inset space ~ \end_inset to \begin_inset space ~ \end_inset Label \family default sets the cursor before the referenced label. This entry will be renamed in the context menu of the label to \family sans Go \begin_inset space ~ \end_inset Back \family default so that you can use it to set the cursor back to the cross-reference. You can also go back with the toolbar button \begin_inset Info type "icon" arg "bookmark-goto 0" \end_inset . \end_layout \begin_layout Standard You can change labels at any time. References to the changed label will automatically be updated so that you do not need to think about this. \end_layout \begin_layout Standard If a cross-reference refers to a non-existent label, you will see in \SpecialChar LyX “BROKEN” in the cross-reference label and two question marks in the output instead of the reference. \end_layout \begin_layout Standard References are described in detail in the section \begin_inset space ~ \end_inset \emph on Referencing Floats \emph default of the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual. \end_layout \begin_layout Section Table of Contents and other Listings \begin_inset Index idx status collapsed \begin_layout Plain Layout Table of contents \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Navigating !

If you have declared a short title for a section heading, as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Short-Titles" \end_inset , it will be used in the TOC instead of the section heading. Section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Numbering-depth" \end_inset describes how the level is adjusted that defines which section types are listed in the TOC. Unnumbered sections are not listed in the TOC. \end_layout \begin_layout Subsection List of Figures, Tables, Listings and Algorithms \begin_inset CommandInset label LatexCommand label name "subsec:List-of-Figures" \end_inset \end_layout \begin_layout Standard Table, figure, listings and algorithm lists are very much like the table of contents.

The appearing dialog has two fields: \family sans Target \family default and \family sans Name \family default . The name is the printed text for the hyperlink. The hyperlink type can be a weblink like this: \begin_inset CommandInset href LatexCommand href name "LyX's homepage" target "https://www.lyx.org" literal "false" \end_inset , an Email address like this: \begin_inset CommandInset href LatexCommand href name "lyx-docs mailing list" target "lyx-docs@lists.lyx.org?subject=LyX's documentation" type "mailto:" literal "false" \end_inset , or a link to a file. The option \family sans Literal \family default in the hyperlink settings dialog allows to input \SpecialChar TeX code to the \family sans Name \family default field. \end_layout \begin_layout Standard You can start applications via a hyperlink when you insert a weblink by adding the prefix \begin_inset Quotes eld \end_inset \family sans run: \family default \begin_inset Quotes erd \end_inset to the link target. \end_layout \begin_layout Standard Hyperlinks will automatically be hyphenated if necessary in the PDF output, and become clickable in the DVI and PDF-output. To set the format of the link text, highlight the hyperlink inset and use the text style dialog. This is for example a hyperlink with bold sans serif text: \family sans \series bold \begin_inset CommandInset href LatexCommand href name "LyX's homepage" target "https://www.lyx.org" literal "false" \end_inset \end_layout \begin_layout Standard The link text color can be changed, when the option \family sans Color links \family default is set in the PDF Properties dialog (menu \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator PDF Properties \family default ). The link text is for example set in this document to blue by adding the option \begin_inset Newline newline \end_inset \series bold urlcolor=blue \series default \begin_inset Newline newline \end_inset to the field \family sans Additional options \family default in the PDF Properties dialog. \end_layout \begin_layout Section Appendices \begin_inset Index idx status collapsed \begin_layout Plain Layout Appendix \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Appendices" \end_inset \end_layout \begin_layout Standard Appendices are created with the menu \family sans Document\SpecialChar menuseparator Start \begin_inset space ~ \end_inset Appendix \begin_inset space ~ \end_inset Here \family default . This menu sets the document from the current cursor position to the end as the appendix part of the book. This part is marked with a red borderline. \end_layout \begin_layout Standard Every chapter (or section) within the appendix part is treated as an appendix, numbered with a capital Latin letter. The appendix subsections are numbered with this letter followed by a dot and the subsection number. All appendix sections can be referenced as if they were normal sections, here two examples: \end_layout \begin_layout Standard Appendix \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "chap:Credits" \end_inset ; Appendix \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Export" \end_inset \end_layout \begin_layout Section Bibliography \begin_inset Index idx status collapsed \begin_layout Plain Layout Bibliography \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Bibliography" \end_inset \end_layout \begin_layout Standard There are two ways of generating the bibliography in a \SpecialChar LyX document. You can include a bibliography database, which is explained in sec. \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Bibliography-databases" plural "false" caps "false" noprefix "false" \end_inset , or you can insert the bibliography manually, using the paragraph environment \family sans Bibliography \family default , which is described in the following section (but see also sec. \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Biblio_environment" \end_inset ). If you want anything other than the numerical citations that are used in this document, such as author-year citations, and if you have more than a handful of references, then you should seriously consider \emph on \emph default using a bibliography database. \end_layout \begin_layout Standard In order to demonstrate the difference between these two approaches, we use two bibliographies in this document, a \family sans Bibliography \family default environment and a database-generated bibliography. As you can see, the bibliography that is created from a database lists only the database entries that are referenced in the document. In other words, the database approach relieves you, amongst other things, from the burden to check which entries you have actually cited. \end_layout \begin_layout Subsection The Bibliography Environment \begin_inset CommandInset label LatexCommand label name "subsec:The-Bibliography-Environment" \end_inset \end_layout \begin_layout Standard Within the \family sans Bibliography \family default environment, every paragraph begins with a gray bibliography box labeled with a number. If you click on it, you will get a dialog in which you can set a \family sans Key \family default and a \family sans Label \family default . The key is the symbolic name by which you will refer to this bibliography entry. Each entry needs to be given a unique key, which is one word consisting of ASCII characters only. \begin_inset Foot status collapsed \begin_layout Plain Layout ASCII means \begin_inset CommandInset href LatexCommand href name "this set" target "https://en.wikipedia.org/wiki/ASCII#Character_set" literal "false" \end_inset of characters: \begin_inset Newline newline \end_inset \begin_inset Flex URL status open \begin_layout Plain Layout https://en.wikipedia.org/wiki/ASCII#Character_set \end_layout \end_inset \end_layout \end_inset For example, our second entry in the bibliography is a book about \SpecialChar LaTeX and we used \begin_inset Quotes eld \end_inset latexcompanion \begin_inset Quotes erd \end_inset , a short form of its title, as the key. \begin_inset Newline newline \end_inset If you set a \family sans Label \family default for the entry, references to it will appear with this label instead of the number of the entry. The option \family sans Literal \family default in the bibliography items settings dialog allows to input \SpecialChar TeX code to the \family sans Label \family default field. \end_layout \begin_layout Standard You can cross-reference a bibliography entry using the menu \family sans Insert\SpecialChar menuseparator Citation \family default or the toolbar button \begin_inset Info type "icon" arg "dialog-show-new-inset citation" \end_inset . A citation reference box is inserted and a citation window will appear containing the available citations. Select one or more keys from the list and \family sans Add \family default them. Then press \family sans OK \family default . The citation reference box will be labeled with the referenced key(s). If you click on the box, the citation window will appear and you can change the reference. \end_layout \begin_layout Standard Citation references appear in the output as the number or the label of the bibliography entry with surrounding brackets. Here are two examples; the first without a label, the second with the label \begin_inset Quotes eld \end_inset Credits \begin_inset Quotes erd \end_inset : \end_layout \begin_layout Standard Have a look at the \family sans \SpecialChar LaTeX Companion Second Edition \family default : \begin_inset CommandInset citation LatexCommand cite key "latexcompanion" literal "true" \end_inset \end_layout \begin_layout Standard The \SpecialChar LyX -Team members are listed in the Credits: \begin_inset CommandInset citation LatexCommand cite key "lyxcredit" literal "true" \end_inset \end_layout \begin_layout Standard You can also produce author-year or author-number citations, using the \SpecialChar LaTeX package \series bold natbib \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! natbib \end_layout \end_inset . In order to do so, the label needs to be given the form \begin_inset Quotes eld \end_inset Author(Year) \begin_inset Quotes erd \end_inset or \begin_inset Quotes eld \end_inset Author A and Author B(Year) \begin_inset Quotes erd \end_inset \emph on without \emph default a blank between the author(s) and the opening parenthesis that delimits the year.

All entries are then indented in the output by the width of the given label. \end_layout \begin_layout Subsection Bibliography databases \begin_inset Index idx status collapsed \begin_layout Plain Layout Bibliography ! Databases \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Bibliography-databases" \end_inset \end_layout \begin_layout Standard Bibliography databases are useful if you use the same references in different documents. \begin_inset Foot status collapsed \begin_layout Plain Layout They are also useful for keeping a database of articles and notes concerning them. Most of the database programs mentioned below allow you to store annotations and reviews along with bibliographical information. \end_layout \end_inset It also makes it very easy to have a uniform layout for all bibliography entries. You can collect the bibliography of all relevant books and articles of your working field in a database. This database can be used for different documents, and by default only the entries cited in a particular document will appear in the bibliography list for that document. This relieves you of the need to keep track of which articles and books you have cited. \end_layout \begin_layout Standard The database is a text file with the file extension \begin_inset Quotes eld \end_inset \family sans .bib \family default \begin_inset Quotes erd \end_inset , containing the bibliography in a special format. The format is explained in \begin_inset CommandInset citation LatexCommand cite key "BibTeX-2" literal "true" \end_inset and in the \SpecialChar LaTeX books ( \begin_inset CommandInset citation LatexCommand cite key "Mittelbach,Kopka,Lamport" literal "true" \end_inset ). The file can be created using any text editor, but normally one uses a special program to create and edit the entries in the database. A list of such programs is maintained on the \SpecialChar LyX Wiki at \begin_inset Flex URL status collapsed \begin_layout Plain Layout https://wiki.lyx.org/BibTeX/Programs \end_layout \end_inset . \end_layout \begin_layout Standard \SpecialChar LyX supports two different approaches to use bibliography databases in a document. Bib\SpecialChar TeX is the classic technique that has been the only way to use such databases for a long time. It is quite established and mature and there is a huge range of existing styles available. But it has its drawbacks, especially when it comes to more complex bibliographi c needs and support for specific languages and scripts. Those are addressed by \series bold biblatex \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! biblatex \end_layout \end_inset . It reads the same database format than Bib\SpecialChar TeX (although it has been significantly extended beyond Bib\SpecialChar TeX 's scope) \begin_inset Foot status collapsed \begin_layout Plain Layout Meaning: While \noun on Biblatex \noun default can handle any classic Bib\SpecialChar TeX database, Bib\SpecialChar TeX might conversely fail to correctly handle databases that use specific \noun on Biblatex \noun default features. \end_layout \end_inset , but it uses a different framework to generate citations and references from it. \end_layout \begin_layout Standard To select if Bib\SpecialChar TeX or \series bold biblatex \series default should be used, set in the document settings (menu \family sans Document\SpecialChar menuseparator Settings \family default ) \begin_inset Index idx status collapsed \begin_layout Plain Layout Document !

Bib\SpecialChar TeX \end_layout \end_inset \end_layout \begin_layout Standard To access a database via Bib\SpecialChar TeX , use the menu \family sans Insert\SpecialChar menuseparator List \family default / \family sans TOC\SpecialChar menuseparator Bib(la)TeX \begin_inset space ~ \end_inset Bibliography \family default . A window will appear in which you can add one or more databases and select a Bib\SpecialChar TeX \family sans style \family default file. The option \family sans Add bibliography to TOC \family default adds a table of contents entry for the bibliography. In the \family sans Content \family default drop box you can select whether to include all the entries in the database in the document or just the cited references. \change_inserted -712698321 1530969762 The \family sans Encoding \family default drop box lets you specify the encoding of the database(s), should this differ from the encoding of the document. \change_unchanged \end_layout \begin_layout Standard The Bib\SpecialChar TeX style file is a text file with the file extension \begin_inset Quotes eld \end_inset \family sans .bst \family default \begin_inset Quotes erd \end_inset that controls how the bibliography entries will appear. Your \SpecialChar LaTeX distribution should provide several of these, and many publishers provide their own style files, so that you don't have to take care of the layout. It is of course possible to write your own style file, but this is something for experts. \begin_inset Foot status collapsed \begin_layout Plain Layout For information on how this is done, have a look at \begin_inset Newline newline \end_inset \begin_inset CommandInset href LatexCommand href target "https://www.ctan.org/tex-archive/biblio/bibtex/contrib/doc/btxhak.pdf" literal "false" \end_inset . \end_layout \end_inset In this document we used the Bib\SpecialChar TeX style \family sans alphadin.bst \family default , which provides an alpha-numeric style in accordance with the German Standards Institute (DIN). \end_layout \begin_layout Standard Inserting a citation reference works as described in the previous section. \end_layout \begin_layout Subsubsection Biblatex \begin_inset Index idx status collapsed \begin_layout Plain Layout Bibliography ! Biblatex \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! biblatex \end_layout \end_inset \end_layout \begin_layout Standard Accessing a database via \series bold biblatex \series default is almost identical to Bib\SpecialChar TeX : Use the menu \family sans Insert\SpecialChar menuseparator List \family default / \family sans TOC\SpecialChar menuseparator Bib(la)TeX \begin_inset space ~ \end_inset Bibliography \family default . In contrary to Bib\SpecialChar TeX you cannot select a \family sans style \family default file \change_inserted -712698321 1531045799 at this place \change_unchanged . The other dialog options are the same as with Bib\SpecialChar TeX . \change_inserted -712698321 1531045867 As for the styles, note the following. \change_unchanged \end_layout \begin_layout Standard \series bold biblatex \series default has two different style files: a bibliography style file (text file with the file extension \begin_inset Quotes eld \end_inset \family sans .bbx \family default \begin_inset Quotes erd \end_inset ) controls how the bibliography entries will look like and a citation style file (text file with the file extension \begin_inset Quotes eld \end_inset \family sans .cbx \family default \begin_inset Quotes erd \end_inset ) controls the look of the citation references in the text. Usually such style files come in pairs and it makes sense to use matching styles. It is nevertheless possible to mix any citation style with any bibliography style. \end_layout \begin_layout Standard \series bold biblatex \series default styles are not set in the \family sans Bib(la)TeX \begin_inset space ~ \end_inset Bibliography \family default dialog, but in the document settings. \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Settings \end_layout \end_inset However, in the dialog in the \family sans Options \family default field, which is only visible if you use \series bold biblatex \series default , you can enter options that determine how the bibliography is printed (for example how its heading will appear). These options are described in detail in the \series bold biblatex \series default manual, \begin_inset CommandInset citation LatexCommand cite key "Biblatex" literal "true" \end_inset . \end_layout \begin_layout Standard Inserting a citation reference works as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:The-Bibliography-Environment" plural "false" caps "false" noprefix "false" \end_inset . \end_layout \begin_layout Subsubsection Bibliography Processors \end_layout \begin_layout Standard To generate the bibliography from a database, \SpecialChar LyX uses a bibliography processor, that is an external program that reads the database, sorts the citations and processes the data in a way it can be included in the document. The classic program is called Bib\SpecialChar TeX . It has the advantage that it is very mature and widespread, but the disadvantag e that it has severe limitations, due to its age. \end_layout \begin_layout Standard Meanwhile, some alternatives have been developed that address some of these limitations. LyX natively supports some of them and lets you select a custom processor. You can do this on a general level in \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Output\SpecialChar menuseparator LaTeX \family default or for individual documents in \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Bibliography \family default . The following variants are available by default: \end_layout \begin_layout Description biber a specific, modern processor \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! biber \end_layout \end_inset developed exclusively for \series bold biblatex \series default (it does not work with Bib\SpecialChar TeX !). \series bold biber \series default provides full Unicode support, unlimited memory and many specific features \series bold biblatex \series default makes use of; if you use the \series bold biblatex \series default approach, it is strongly recommended to use \series bold biber \series default . \end_layout \begin_layout Description bibtex the standard; does not allow special characters in bibliography entries that are not possible to encode in a 7-bit encoding, limited memory, works with all bibliography packages, although it will probably fail with \series bold biblatex \series default bibliographies due to the limited memory. \end_layout \begin_layout Description bibtex8 allows all characters that are possible to encode in an 8-bit encoding (but no Unicode support), larger memory than \family sans bibtex \family default , works with all bibliography packages, although more complex \series bold biblatex \series default bibliographies will exceed its limits, and not all \series bold biblatex \series default features are supported. \end_layout \begin_layout Standard By default (with the \family sans Processor \family default set in \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Bibliography \family default and with \family sans Automatic \family default as setting for the \family sans Processor \family default in \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Output\SpecialChar menuseparator LaTeX \family default ), \SpecialChar LyX selects an appropriate (available) processor for the current bibliography approach ( \series bold biber \series default for \series bold biblatex \series default , \family sans bibtex \family default for Bib\SpecialChar TeX -based bibliography styles). This should suit most needs. \end_layout \begin_layout Standard In Japanese documents, a specific processor is used. By default this is pBib\SpecialChar TeX (in \SpecialChar LyX \family sans pbibtex \family default ), a Bib\SpecialChar TeX variant specifically aimed at Japanese. You can adjust it in \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Output\SpecialChar menuseparator LaTeX \family default . \end_layout \begin_layout Standard Selected bibliography processors can be controlled with options that you can add below the selection. Before adding options, it is strongly recommended that you read the manual of Bib\SpecialChar TeX or \series bold biber \series default , \begin_inset CommandInset citation LatexCommand cite key "BibTeX,biber" literal "true" \end_inset . \end_layout \begin_layout Subsubsection Customizing \end_layout \begin_layout Standard \SpecialChar LyX supports some specific tasks such as sectioned bibliographies and multiple bibliographies. These are explained in detail in section \emph on Customizing Bibliographies \emph default \emph on with Bib\SpecialChar TeX or Biblatex \emph default of the \emph on Additional Features \emph default manual. \end_layout \begin_layout Subsection Citation Format \begin_inset Index idx status collapsed \begin_layout Plain Layout Bibliography ! Citation format \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Citation-Format" \end_inset \end_layout \begin_layout Standard Many different citation formats are common, e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset numerical citation (as \begin_inset Quotes eld \end_inset 1 \begin_inset Quotes erd \end_inset like in this document), alpha-numerical citations (as \begin_inset Quotes eld \end_inset Mil08 \begin_inset Quotes erd \end_inset ) or author-year citations (as \begin_inset Quotes eld \end_inset Miller (2008a) \begin_inset Quotes erd \end_inset ). \SpecialChar LyX supports these formats via specific citation packages and their style files. \end_layout \begin_layout Standard By default a simple numeric citation style is used. In \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Bibliography \family default \begin_inset Index idx status collapsed \begin_layout Plain Layout Document ! Settings \end_layout \end_inset you have a range of other options, depending on your preferred bibliography approach. With the \family sans Bibliography \family default environment your only choice besides manual formatting of the bibliography labels, is there to use \family sans Natbib \begin_inset space ~ \end_inset (BibTeX) \family default \series bold \series default as \family sans Style \begin_inset space ~ \end_inset format \family default which gives you author-year and author-numerical citations (see above \begin_inset CommandInset ref LatexCommand ref reference "subsec:The-Bibliography-Environment" \end_inset for details). \end_layout \begin_layout Standard With a bibliography database (see \begin_inset CommandInset ref LatexCommand ref reference "subsec:Bibliography-databases" plural "false" caps "false" noprefix "false" \end_inset ) one has in contrary to the \family sans Bibliography \family default environment full access to the formatting styles. These style formats are available: \end_layout \begin_layout Description Basic \begin_inset space ~ \end_inset (BibTeX) the default Bib\SpecialChar TeX -based approached without any additional packages (simple numeric citations). \end_layout \begin_layout Description Biblatex loads the package \series bold biblatex \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! biblatex \end_layout \end_inset and lets you select a style in the dropdown boxes \family sans Biblatex citation style \family default and \family sans Biblatex bibliography style \family default below. Options to the package \series bold biblatex \series default can be entered in the \family sans Options \family default field. \end_layout \begin_layout Description Biblatex \begin_inset space ~ \end_inset (natbib \begin_inset space ~ \end_inset mode) loads the package \series bold biblatex \series default with the natbib compatibility mode. This is a specific variant for users who switch an existing document that uses \series bold natbib \series default or want to emulate \family sans the \family default \series bold natbib \series default behavior very closely. Compared to normal \family sans Biblatex \family default this option has some additional styles. All \series bold biblatex \series default styles are also supported by this variant. \end_layout \begin_layout Description Jurabib \begin_inset space ~ \end_inset (BibTeX) loads the package \series bold jurabib \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! jurabib \end_layout \end_inset which provides author-year styles particularly suited for law studies. \end_layout \begin_layout Description Natbib \begin_inset space ~ \end_inset (BibTeX) loads the package \series bold natbib \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! natbib \end_layout \end_inset which provides citation styles particularly suited for the humanities. \end_layout \begin_layout Standard The \family sans Biblatex \family default and \family sans Natbib \family default style formats provide the choice between author-year and author-numerical citation styles. You have to select one style in the dropdown box \family sans Variant \family default . Note that for the \family sans Biblatex \family default formats, this only affects the appearance in the \SpecialChar LyX workarea. Whether the output uses numerical, author-year or another format such as alpha-numerical depends only on the selected \family sans Biblatex citation style \family default . However, when switching between Author-year and Author-number, a suitable style is proposed. With \family sans Natbib \family default , on the other hand, the dialog selection will ultimately determine the style. \end_layout \begin_layout Standard For any author-year and author-numerical selection, multiple style variants are available in the \family sans Citation \family default dialog. Some selections also provide further options like the option to uppercase a name prefix such as \begin_inset Quotes eld \end_inset van Beethoven \begin_inset Quotes erd \end_inset (to \begin_inset Quotes eld \end_inset Van Beethoven \begin_inset Quotes erd \end_inset ) or to expand or reduce the number of displayed others (i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space \space{} \end_inset use or don't use \begin_inset Quotes eld \end_inset et al. \begin_inset Quotes erd \end_inset ). \end_layout \begin_layout Standard In the citation dialog you can also set text to appear after a citation reference, e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset page numbers, which will then be formatted according to the style's needs (e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset with or without \begin_inset Quotes eld \end_inset pp. \begin_inset Quotes erd \end_inset ). The option \family sans Literal \family default in the citation dialog allows to input \SpecialChar TeX code to the fields \family sans Text \begin_inset space ~ \end_inset before \family default and \family sans Text \begin_inset space ~ \end_inset after \family default . Here is a simple example where the text \begin_inset Quotes eld \end_inset Chapter \begin_inset space ~ \end_inset 3 \begin_inset Quotes erd \end_inset appears after the reference: \end_layout \begin_layout Quote Have a look at \begin_inset CommandInset citation LatexCommand cite after "Chapter 3" key "latexcompanion" literal "false" \end_inset . \end_layout \begin_layout Standard All styles except for \family sans Basic (BibTeX) \family default also provide the feature to add text that precedes the reference (such as \begin_inset Quotes eld \end_inset cf. \begin_inset Quotes erd \end_inset ). This text is then also included in the parentheses, if the style requires this. \end_layout \begin_layout Standard Note that these pre- and postnotes apply to the whole citation. So if you refer to multiple references at once, the prenote will precede the first citation in the list, the postnote will follow the last. Some \family sans Biblatex \family default styles allow to add pre- and postnotes to any individual reference in a multi-citation (so-called \begin_inset Quotes eld \end_inset qualified citation lists \begin_inset Quotes erd \end_inset ). \SpecialChar LyX supports this. If you use such a style and if the current reference includes multiple items the \family sans Citation \family default dialog will display three columns in the field \family sans Selected Citations \family default : \family sans Text \begin_inset space ~ \end_inset before \family default , \family sans Cite \begin_inset space ~ \end_inset key \family default and \family sans Text \begin_inset space ~ \end_inset after \family default . If you double-click on an item's \family sans Text \begin_inset space ~ \end_inset before \family default or \family sans Text \begin_inset space ~ \end_inset after \family default field, you can add such individual pre- and postnotes.

A box is inserted containing the text that appears in the index. The word where the cursor is in or the currently highlighted text is proposed by \SpecialChar LyX as the index entry. \end_layout \begin_layout Standard The index list is inserted in the document with the menu \family sans Insert\SpecialChar menuseparator List/TOC\SpecialChar menuseparator Index \begin_inset space ~ \end_inset List \family default . A light blue box labeled \begin_inset Quotes eld \end_inset \family sans Index \family default \begin_inset Quotes erd \end_inset will show the place where the index is printed in the output. The index list box is not clickable like other \SpecialChar LyX -boxes. \end_layout \begin_layout Standard We give a short overview of the index commands in the next subsections. For a detailed description of \SpecialChar LaTeX 's index mechanism, have a look at one of the \SpecialChar LaTeX books \begin_inset CommandInset citation LatexCommand cite key "latexcompanion,latexguide,latexbook" literal "true" \end_inset . \end_layout \begin_layout Subsection Grouping Index Entries \begin_inset Index idx status collapsed \begin_layout Plain Layout Index ! Grouping \end_layout \end_inset \end_layout \begin_layout Standard Index entries are often grouped to offer the reader a fast search in the index. We want to group for example the index entries for itemized and enumerated lists under the entry \begin_inset Quotes eld \end_inset Lists \begin_inset Quotes erd \end_inset . First we create the entry \begin_inset Quotes eld \end_inset Lists \begin_inset Quotes erd \end_inset in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Lists" \end_inset . In the text field for the itemized list index entry in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Itemize" \end_inset , we insert the command \end_layout \begin_layout Standard \series bold Lists ! Itemize \end_layout \begin_layout Standard and the command \end_layout \begin_layout Standard \series bold Lists ! Enumerate \end_layout \begin_layout Standard for the enumerated list in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Enumerate" \end_inset . \end_layout \begin_layout Standard The exclamation mark \begin_inset Quotes eld \end_inset ! \begin_inset Quotes erd \end_inset marks the grouping levels. You can have three levels; every index level is indented a bit more. An index entry for the higher levels is not required. If we don't have an index entry for \begin_inset Quotes eld \end_inset Lists \begin_inset Quotes erd \end_inset , it will be printed anyway, but without a page number. \end_layout \begin_layout Subsection Page Ranges \begin_inset Index idx status collapsed \begin_layout Plain Layout Index ! Page ranges \end_layout \end_inset \end_layout \begin_layout Standard Normally an index entry will appear with the page number of the indexed section. But sometimes you want to index more pages under the same entry. For example, if we want to index the paragraph environments, we create an index entry in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Paragraph-Environments" \end_inset with the command \end_layout \begin_layout Standard \series bold Paragraph environments|( \end_layout \begin_layout Standard and another entry at the end of section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LyX-Code" \end_inset with the command \end_layout \begin_layout Standard \series bold Paragraph environments|) \end_layout \begin_layout Standard The commands \begin_inset Quotes eld \end_inset \series bold |( \series default \begin_inset Quotes erd \end_inset and \begin_inset Quotes eld \end_inset \series bold |) \series default \begin_inset Quotes erd \end_inset respectively start and end the index range. You can also add the same index entry at different places in the document. They appear in the output under one entry with a comma separated list of the pages of the indexed document parts. An example is the index entry \begin_inset Quotes eld \end_inset Document ! Settings \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Subsection Cross referencing \begin_inset Index idx status collapsed \begin_layout Plain Layout Index ! Cross referencing \end_layout \end_inset \end_layout \begin_layout Standard It is also possible to refer to another index entry. We referred for example in the index entry \begin_inset Quotes eld \end_inset GIF \begin_inset Quotes erd \end_inset (in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Image-Formats" \end_inset ) to the index entry \begin_inset Quotes eld \end_inset Image formats \begin_inset Quotes erd \end_inset in the same section using the entry \end_layout \begin_layout Standard \series bold GIF|see{Image formats} \end_layout \begin_layout Standard where the braces have to be inserted as \SpecialChar TeX Code. The text within the braces is the referenced entry. The reference will appear in the output without a page number. \end_layout \begin_layout Subsection Index Entry Order \begin_inset Index idx status collapsed \begin_layout Plain Layout Index ! Entry order \end_layout \end_inset \end_layout \begin_layout Standard If you use accented characters in the index entry the entries might not follow the rules for the index order. The index entries are sorted alphabetically but \SpecialChar LaTeX \begin_inset Foot status collapsed \begin_layout Plain Layout The index generating is done in the background by an extra program, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Index-Program" \end_inset . \end_layout \end_inset does not know how to sort accents in different languages. We have created as an example the three dummy index entries \begin_inset Quotes eld \end_inset maison \begin_inset Quotes erd \end_inset , \begin_inset Quotes eld \end_inset maïs \begin_inset Quotes erd \end_inset , and \begin_inset Quotes eld \end_inset maître \begin_inset Quotes erd \end_inset . \begin_inset Index idx status collapsed \begin_layout Plain Layout Dummy entries ! maïs \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Dummy entries ! maître \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Dummy entries ! maïs@maison \end_layout \end_inset They will be sorted in the order maïs, maître, maison but we want the order maïs, maison, maître. To achieve this, we use the command \end_layout \begin_layout Standard \series bold previous entry@current entry \end_layout \begin_layout Standard In our case we want to have \begin_inset Quotes eld \end_inset maison \begin_inset Quotes erd \end_inset after \begin_inset Quotes eld \end_inset maïs \begin_inset Quotes erd \end_inset and write therefore for the index entry of maison: \end_layout \begin_layout Standard \series bold maïs@maison \end_layout \begin_layout Standard The previous entry need not be a real existing entry. You can also use another word to tell \SpecialChar LaTeX the entry order. See the next subsection for an example. \end_layout \begin_layout Subsection Index Entry Layout \begin_inset Index idx status collapsed \begin_layout Plain Layout Index ! Entry layout \end_layout \end_inset \end_layout \begin_layout Standard You can change the appearance of index entries via the text style dialog. \begin_inset Index idx status open \begin_layout Plain Layout Dummy entries ! \shape italic This is an italic dummy entry \end_layout \end_inset You can also format the page number using the character \begin_inset Quotes eld \end_inset | \begin_inset Quotes erd \end_inset followed by a \SpecialChar LaTeX -command without a backslash. We can write for example \end_layout \begin_layout Standard \series bold italic page number:|textit \end_layout \begin_layout Standard to get the page number in italic. \begin_inset Index idx status open \begin_layout Plain Layout Dummy entries ! italic page number:|textit \end_layout \end_inset Normally all \SpecialChar LaTeX -commands begin with a backslash, but in this special case \begin_inset Quotes eld \end_inset \series bold |command \series default \begin_inset Quotes erd \end_inset means \series bold \backslash command{page \begin_inset space ~ \end_inset number} \series default . Have a look at section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-Syntax" \end_inset to learn more about the \SpecialChar LaTeX -syntax. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Formatting single index entries only works when you use the program \family sans makeindex \family default to generate the index, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Index-Program" \end_inset . If you use \family sans xindy \family default , this will not work for anything other than bold or italic text. This is because \family sans xindy \family default requires you to define semantic elements before they can be used, see \begin_inset CommandInset citation LatexCommand cite after "p. 678 ff." key "latexcompanion" literal "true" \end_inset for details. \end_layout \end_inset \end_layout \begin_layout Standard In general, we encourage you to not format page numbers directly as shown above. Instead, you should define a macro in the preamble and use that. Maybe you want all page references italic that refer to a definition of the indexed term, so that users can easily find definitions. If so, put the following in the preamble \end_layout \begin_layout Standard \series bold \backslash newcommand{ \backslash IndexDef}[1]{ \backslash textit{#1}} \end_layout \begin_layout Standard and write \end_layout \begin_layout Standard \series bold my entry|IndexDef \end_layout \begin_layout Standard in the index entry. \begin_inset Index idx status open \begin_layout Plain Layout Dummy entries ! my entry|IndexDef \end_layout \end_inset The advantage is that, if you change your mind later or if your publisher insists that definitions must not be italic but bold, you just need to change the macro in the preamble, not every single index entry. \end_layout \begin_layout Standard You can also change the layout for the whole index. For example, we marked the index list box of this document as bold to get a bold font for all index entries. For more advanced tasks you have to set up a so-called \emph on Index Style File \emph default , see the \family sans makeindex \family default or \family sans xindy \family default documentation for details, \begin_inset CommandInset citation LatexCommand cite key "makeindex,xindy" literal "true" \end_inset . \end_layout \begin_layout Subsection Index Program \begin_inset Index idx status collapsed \begin_layout Plain Layout Index ! Program \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:Index-Program" \end_inset \end_layout \begin_layout Standard If the index generation program \family sans xindy \family default is installed, \SpecialChar LyX uses it for index generation; otherwise the program \family sans makeindex \family default , the program that is part of every \SpecialChar LaTeX distribution, is used. \begin_inset Foot status collapsed \begin_layout Plain Layout \family sans Makeindex \family default is very old, no longer under development and has many pitfalls, notably that it was developed with only the English language in mind. So it fails to sort anything other than a monolingual English text correctly. We have shown above how to fix this sorting. However, if you are writing in another than the English language, consider to use \family sans xindy \family default . \end_layout \end_inset Both programs can be controlled by options that can be set in \SpecialChar LyX 's preferences dialog, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:LaTeX-settings" \end_inset . The available options are listed and explained in \begin_inset CommandInset citation LatexCommand cite key "makeindex-man,xindy" literal "true" \end_inset . In this dialog, you can also specify an alternative program to generate the index. \end_layout \begin_layout Standard If you need specific options or an alternative index program only for a given document, you can define the program and\SpecialChar breakableslash or the options in \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Indexes \family default . This is especially useful if you need to pass language-specific options to the index program or if you need a specific layout style. \end_layout \begin_layout Subsection Multiple Indexes \end_layout \begin_layout Standard In many fields it is common to have more than one index. For instance, you might need to set up a separate \begin_inset Quotes eld \end_inset Index of Names \begin_inset Quotes erd \end_inset next to the standard index. \SpecialChar LaTeX does not provide this possibility out of the box, but there are packages that add this feature. \SpecialChar LyX uses the \series bold splitidx \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! splitidx \end_layout \end_inset package to generate multiple indexes. The package is included in all recent \SpecialChar LaTeX distributions. \begin_inset Foot status collapsed \begin_layout Plain Layout If yours does not ship it, consult the \SpecialChar TeX catalogue, \begin_inset CommandInset citation LatexCommand cite key "TeXCatalogue" literal "true" \end_inset . Note that the package does not only consist of a \SpecialChar LaTeX style, but it also includes specific preprocessor programs that need to be installed as well. Please consult the package's manual for details. \end_layout \end_inset \end_layout \begin_layout Standard To set up \SpecialChar LyX for the use of multiple indexes, go to \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Indexes \family default and select the option \family sans Use multiple Indexes \family default . Note that the list \family sans Available Indexes \family default already contains the standard index \begin_inset Quotes eld \end_inset Index \begin_inset Quotes erd \end_inset . To add further indexes, add the name of the index (in the form that should also appear as a heading) to the \family sans New \family default input field and press the \family sans Add \family default button. The new index now also appears in the list. If you like, you can attribute an alternative \SpecialChar LyX label color to the new index. \end_layout \begin_layout Standard Once the document changes have been applied, you can find the new index list in \family sans Insert\SpecialChar menuseparator List/TOC \family default and the \family sans Insert \family default menu has a separate entry for each of the defined indexes. The workflow is basically the same as for the default index, but there are additional features: \end_layout \begin_layout Itemize If you want to change the attribution of a specific index entry, right-clicking on the entry's label will open a dialog where you can do that. \end_layout \begin_layout Itemize By right-clicking on an index, you can change its type. Furthermore, you can specify an index to be a \family sans Subindex \family default . If you do that, the heading of that list will be decreased by one level. For example, if you use a book class, where the standard index heading is defined as a chapter, subindexes will be defined as sections and can thus be nested to the non-subindexes. \end_layout \begin_layout Itemize The option \family sans Literal \family default allows to use \SpecialChar TeX code in the name of the index. \end_layout \begin_layout Section Nomenclature/Glossary \begin_inset Index idx status collapsed \begin_layout Plain Layout Nomenclature \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Glossary|see \begin_inset ERT status collapsed \begin_layout Plain Layout { \end_layout \end_inset Nomenclature \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Nomenclature" \end_inset \end_layout \begin_layout Standard Sometimes you need to provide a list of technical terms or symbols that are mentioned in your document with a brief explanation of them – a so called nomenclature or glossary. \end_layout \begin_layout Standard To be able to create nomenclatures or glossaries, you need the \SpecialChar LaTeX package \series bold nomencl \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! nomencl \end_layout \end_inset installed. You find it in the \SpecialChar TeX catalogue, \begin_inset CommandInset citation LatexCommand cite key "TeXCatalogue" literal "true" \end_inset or in the package manager of your \SpecialChar LaTeX -system. \end_layout \begin_layout Standard A nomenclature entry is created if you place the cursor after a symbol entry and then use the menu \family sans Insert\SpecialChar menuseparator \family default N \family sans omenclature \begin_inset space ~ \end_inset Entry \family default or the toolbar button \begin_inset Info type "icon" arg "nomencl-insert" \end_inset .

You can later change the activation state of the branch by right-clicking on them. \end_layout \begin_layout Standard Here is an example, where only the question text appears, the answer branch is deactivated and therefore does not appear in the output: \end_layout \begin_layout Standard \begin_inset Branch Question inverted 0 status open \begin_layout Standard \series bold Question: \series default Who was the first physics Nobel prize winner? \end_layout \end_inset \end_layout \begin_layout Standard \begin_inset Branch Answer inverted 0 status collapsed \begin_layout Standard \series bold Answer: \series default Wilhelm Conrad Röntgen \end_layout \end_inset \end_layout \begin_layout Standard If you activate \family sans Filename Suffix \family default in \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator Branches \family default , the name of the active branches will be appended to the file name at export. Consider for example a file \begin_inset Quotes eld \end_inset Exam.lyx \begin_inset Quotes erd \end_inset which has the above branches. If \begin_inset Quotes eld \end_inset Filename Suffix \begin_inset Quotes erd \end_inset is active, the PDF export file would be called \begin_inset Quotes eld \end_inset Exam.pdf \begin_inset Quotes erd \end_inset if both the \begin_inset Quotes eld \end_inset Question \begin_inset Quotes erd \end_inset and \begin_inset Quotes eld \end_inset Answer \begin_inset Quotes erd \end_inset branch were inactive, \begin_inset Quotes eld \end_inset Exam-Question.pdf \begin_inset Quotes erd \end_inset if only the \begin_inset Quotes eld \end_inset Question \begin_inset Quotes erd \end_inset branch was active, likewise \begin_inset Quotes eld \end_inset Exam-Answer.pdf \begin_inset Quotes erd \end_inset if only the \begin_inset Quotes eld \end_inset Answer \begin_inset Quotes erd \end_inset branch was active, and \begin_inset Quotes eld \end_inset Exam-Question-Answer.pdf \begin_inset Quotes erd \end_inset if both branches were active. This helps you to export different versions of your document easily. \begin_inset VSpace bigskip \end_inset \end_layout \begin_layout Standard There are also inverted branch insets, whose content is output just in case the branch is \emph on not \emph default activated.

This means that the reader of your document will be able to click on a table of contents entry or on a reference to move to the cross-referenced part of the document. \end_layout \begin_layout Standard The header information in the dialog tab \family sans General \family default is saved together with the PDF as file properties. Many programs are able to extract this information, for example, automatically to recognize who the author is and what the PDF is about. This is very useful to sort, classify or use PDFs for bibliography issues. When the option \family sans Automatically \begin_inset space ~ \end_inset fill \begin_inset space ~ \end_inset header \family default is set, \SpecialChar LyX tries to extract the header information from your document title and author entries. The option \family sans Load \begin_inset space ~ \end_inset in \begin_inset space ~ \end_inset fullscreen \begin_inset space ~ \end_inset mode \family default will open the PDF in fullscreen mode, which is useful for presentations. \end_layout \begin_layout Standard You can specify in the dialog tab \family sans Hyperlinks \family default how the links will look and if links for bibliographical backreferences are created. The \family sans Break \begin_inset space ~ \end_inset links \begin_inset space ~ \end_inset over \begin_inset space ~ \end_inset lines \family default option allows long links to be split; \family sans No \begin_inset space ~ \end_inset frames \begin_inset space ~ \end_inset around \begin_inset space ~ \end_inset links \family default and \family sans Color \begin_inset space ~ \end_inset links \family default both turn off the default behavior of enclosing all links in frames; \family sans Color \begin_inset space ~ \end_inset links \family default colors the different links.

For example, in this document they were changed with the additional options: \end_layout \begin_layout Standard \series bold linkcolor=black, citecolor=black, urlcolor=blue, filecolor=blue \end_layout \begin_layout Standard If the option \family sans Backreferences \family default is set, the hyperlinks will appear in the bibliography after the different entries, showing, depending on the option selected, the number of the section, slide or page where the entry is referenced. \end_layout \begin_layout Standard In the dialog tab \family sans Bookmarks \family default you can specify if PDF-bookmarks should be created for every section of your document to make it easier for readers to navigate through the document. You can decide if the bookmarks should be numbered like your document sections or not. With the \family sans Open bookmarks \family default \family sans Level \family default you can specify what sectioning level should be displayed in the bookmarks when opening the PDF. For example level \begin_inset space ~ \end_inset 2 will display all sections and subsections, while level \begin_inset space ~ \end_inset 1 will only display the sections. \end_layout \begin_layout Standard PDF properties are also used in this document. When you look in its document settings, you can see that some additional \series bold hyperref \series default options are used.

All the time packages are being updated and new ones added. This has the advantage that you can typeset nearly everything as there is a \SpecialChar LaTeX -package for every problem, though \SpecialChar LyX cannot support all packages and their commands. \end_layout \begin_layout Standard But don't worry, you can use any \SpecialChar LaTeX -command directly in \SpecialChar LyX inside the \SpecialChar TeX Code box. A \SpecialChar TeX Code box is created by the menu \family sans Insert\SpecialChar menuseparator TeX \begin_inset space ~ \end_inset Code \family default or by the toolbar button \begin_inset Info type "icon" arg "ert-insert" \end_inset (shortcut \begin_inset Info type "shortcut" arg "ert-insert" \end_inset ). The box can be opened by left-clicking and closed by right-clicking on it and selecting \family sans Close Inset \family default . \end_layout \begin_layout Standard You can insert complete or incomplete commands as \SpecialChar TeX Code. Incomplete means that the command argument can be Standard \SpecialChar LyX text. For example, if you want to draw a frame around a word \begin_inset Foot status collapsed \begin_layout Plain Layout The LyX way would be to use a framed box. \end_layout \end_inset and are therefore using the \SpecialChar LaTeX -command \series bold \backslash fbox \series default , you can write the command part \series bold \backslash fbox{ \series default in a \SpecialChar TeX Code box before the word and the closing brace \series bold } \series default in a second \SpecialChar TeX Code box behind the word. The word between the two \SpecialChar TeX Code boxes is then the argument as it is in the following example: \end_layout \begin_layout Standard \begin_inset Graphics filename clipart/ERT.png scale 95 \end_inset \end_layout \begin_layout Standard gives \end_layout \begin_layout Standard This is a line with a \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash fbox{ \end_layout \end_inset framed \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset word. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default At the end of \SpecialChar LaTeX -commands without parameters, you have to insert a space to let \SpecialChar LaTeX know that the command is finished. \end_layout \end_inset \end_layout \begin_layout Subsection A Short Introduction to the \SpecialChar LaTeX Syntax \begin_inset Argument 1 status collapsed \begin_layout Plain Layout The \SpecialChar LaTeX Syntax \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX Syntax \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "subsec:LaTeX-Syntax" \end_inset \end_layout \begin_layout Standard When you write larger documents or books, you will need to know something about the \SpecialChar LaTeX -commands that \SpecialChar LyX uses in the background. Because \SpecialChar LaTeX is based on commands, you can \begin_inset Quotes eld \end_inset program \begin_inset Quotes erd \end_inset your text. This has the advantage that the layout of the document can be changed at any time if you know the right commands. For example, imagine you have to write a manual for a product and the deadline is the end of the day. Your boss has just complimented you for your good work but wants to have all caption labels bold. But you have over a hundred figure and table captions with non-bold labels in your manual. Of course it is impossible to change all caption labels manually in one day. \end_layout \begin_layout Standard Now \SpecialChar LaTeX comes into play. As mentioned above, for every problem there exists a \SpecialChar LaTeX -package. First you have to find out which and therefore look in the \SpecialChar LaTeX package database, \begin_inset CommandInset citation LatexCommand cite key "Catalogue" literal "true" \end_inset . \end_layout \begin_layout Standard As result you find that the package \series bold caption \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! caption \end_layout \end_inset is what you need. To use a package, you have to load it in the document preamble (menu \family sans Document\SpecialChar menuseparator Settings \family default \SpecialChar menuseparator \family sans LaTeX \begin_inset space ~ \end_inset Preamble \family default ) with the command \end_layout \begin_layout Standard \series bold \backslash usepackage[options]{package name} \end_layout \begin_layout Standard All \SpecialChar LaTeX commands begin with a backslash, the command argument is set within two braces and the options are set within two brackets. Note that not all commands have an argument and options. \end_layout \begin_layout Standard In your case the package name is \series bold caption \series default . After a look in the documentation of the package, you know that the option \series bold labelfont=bf \series default will change the font of all caption labels to bold. So you add the command \end_layout \begin_layout Standard \series bold \backslash usepackage[labelfont=bf]{caption} \end_layout \begin_layout Standard to the preamble and the problem is solved. \begin_inset Foot status collapsed \begin_layout Plain Layout For more commands provided by the \series bold caption \series default package, have a look at its documentation, \begin_inset CommandInset citation LatexCommand cite key "caption" literal "true" \end_inset . \end_layout \end_inset \end_layout \begin_layout Standard Note that some document classes have built-in solutions for well-known problems like your case. For example if you use a \family sans KOMA-Script \family default class, you don't need the package \series bold caption \series default , you can instead write \end_layout \begin_layout Standard \series bold \backslash setkomafont{captionlabel}{ \backslash bfseries} \end_layout \begin_layout Standard in the preamble and the problem is solved. So if you plan to write a large document, you should have a look at the documentation of the document class you want to use. ( \series bold \backslash setkomafont \series default is an example of a command with more than one argument.) \end_layout \begin_layout Standard Commands in the preamble affect the whole document, while commands in the text affect only the text after the command or only the text used as command argument. To insert a \SpecialChar LaTeX -command in text, use the \SpecialChar TeX Code box as described in the previous section. \end_layout \begin_layout Standard If you want to learn more about \SpecialChar LaTeX and its syntax, have a look at the \SpecialChar LaTeX -books \begin_inset CommandInset citation LatexCommand cite key "latexcompanion,latexguide" literal "true" \end_inset . \end_layout \begin_layout Standard \begin_inset Newpage clearpage \end_inset \end_layout \begin_layout Standard \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash pagestyle{fancy} \end_layout \end_inset \begin_inset Note Note status collapsed \begin_layout Plain Layout switches temporarily to a page style with custom header and footer line \end_layout \end_inset \end_layout \begin_layout Left Header \begin_inset Argument 1 status collapsed \begin_layout Plain Layout \end_layout \end_inset \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash rightmark \end_layout \end_inset \begin_inset Note Note status collapsed \begin_layout Plain Layout defines the header line as described below \end_layout \end_inset \end_layout \begin_layout Center Header \begin_inset Argument 1 status collapsed \begin_layout Plain Layout \end_layout \end_inset \end_layout \begin_layout Right Header \begin_inset Argument 1 status collapsed \begin_layout Plain Layout \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash leftmark \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Left Footer \begin_inset Argument 1 status collapsed \begin_layout Plain Layout \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash thepage \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Center Footer \begin_inset Argument 1 status collapsed \begin_layout Plain Layout \family sans \series bold \color red \SpecialChar LyX 's user guide \end_layout \end_inset Magic code: \begin_inset Newline newline \end_inset \begin_inset Formula $\Upsilon=\frac{\sqrt[3]{\aleph}}{\spadesuit}$ \end_inset \end_layout \begin_layout Right Footer \begin_inset Argument 1 status collapsed \begin_layout Plain Layout \end_layout \end_inset \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash Roman{page} \end_layout \end_inset \end_layout \begin_layout Section Customized Page Headers and Footers \begin_inset CommandInset label LatexCommand label name "sec:Customized-Page-Headers" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Document !

These environments can be selected in the environment pull-down box. \end_layout \begin_layout Standard Normally, headers and footers are set up at the beginning of the document. But you can change them anywhere you want to.

Check what these are before you specify your own customized page headers and footers. \end_layout \end_inset \end_layout \begin_layout Subsection Definition \end_layout \begin_layout Standard To define your header line, add all three header environments. The things you add to each environment appear on odd numbered pages, the things in the optional arguments on even numbered pages. For single-sided documents, the optional arguments will not be used and can be omitted. If you leave a header environment or its argument empty, nothing appears in the output. Defining the footer line works similarly. \end_layout \begin_layout Standard For the definition, you will need some \SpecialChar LaTeX -commands that are inserted as \SpecialChar TeX code (menu \family sans Insert\SpecialChar menuseparator TeX \begin_inset space ~ \end_inset Code \family default ): \end_layout \begin_layout Description \backslash thepage prints the current page number \end_layout \begin_layout Description \backslash Roman{page} prints the current page number with capital roman numerals \end_layout \begin_layout Description \backslash roman{page} prints the current page number with small roman numerals \end_layout \begin_layout Description \backslash leftmark prints the current section number and title. If the document has chapters, it prints the current chapter number and title instead. It is called \begin_inset Quotes eld \end_inset leftmark \begin_inset Quotes prd \end_inset because it usually goes in a left header. \end_layout \begin_layout Description \backslash rightmark prints the current subsection number and title. If the document has chapters, it prints the current section number and title instead. It is normally used in the right header. \end_layout \begin_layout Subsection Default header/footer \end_layout \begin_layout Standard The custom header/footer is not empty by default. The default header contains the chapter and section title and the center footer has the page number. In order to remove unwanted entries from the header/footer, include the relevant header/footer style in your document, but leave it blank. So, if you do not want a page number in the footer, include a blank \family sans Center \begin_inset space ~ \end_inset Footer \family default style. \end_layout \begin_layout Subsection Appearance \end_layout \begin_layout Standard The header and footer will appear on normal pages. Some pages are different. The title page has a header/footer environment of its own, and so does any page that starts a new part or chapter in your book. Such pages will not have the custom headers/footers, but that is normal. There is for example no need to print a header with the chapter name on the chapter page where the chapter heading is in big bold letters anyway. \end_layout \begin_layout Subsubsection Header and footer decoration line \end_layout \begin_layout Standard By default, you get a 0.4 \begin_inset space \thinspace{} \end_inset pt thick line below the header and no footer line. This can be changed in the document preamble with the commands \series bold \backslash headrulewidth \series default and \series bold \backslash footrulewidth \series default in the following way: \end_layout \begin_layout Standard \series bold \backslash renewcommand{ \backslash headrulewidth}{thickness} \end_layout \begin_layout Standard where thickness is a size in standard units like \family sans \emph on pt \family default \emph default or \family sans \emph on mm \family default \emph default . If you don't want a line, set the thickness to 0 \begin_inset space \thinspace{} \end_inset pt. \end_layout \begin_layout Standard The lines can also be colored, but this requires more knowledge of \SpecialChar LaTeX . If you really need this, have a look at the Internet or in section \begin_inset space ~ \end_inset 4.4 of the book \begin_inset CommandInset citation LatexCommand cite key "Mittelbach" literal "true" \end_inset . \end_layout \begin_layout Subsubsection Several header/footer lines \end_layout \begin_layout Standard In case you need more than one text line as a header/footer, you can do this by adding a ragged line break in the style definition. However, the default height of the header/footer is only the height of one text line. To expand the height, redefine the \SpecialChar LaTeX length \series bold \backslash headheight \series default or \series bold \backslash footheight \series default with this entry in \family sans Document\SpecialChar menuseparator Settings\SpecialChar menuseparator LaTeX \begin_inset space ~ \end_inset Preamble \family default : \end_layout \begin_layout Standard \series bold \backslash setlength{ \backslash headheight}{height} \end_layout \begin_layout Standard where \series bold height \series default is a size in standard units (e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset \series bold 1cm \series default ). If you don't know how much space is needed for the height, define your header/footer and preview your document as a PDF. Then open the \SpecialChar LaTeX logfile with the menu \family sans Document\SpecialChar menuseparator LaTeX \begin_inset space ~ \end_inset Log \family default and use the button \family sans Next \begin_inset space ~ \end_inset Warning \family default to see if you can find a warning about the package \series bold fancyhdr \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! fancyhdr \end_layout \end_inset . If there is such a warning, it contains the space that you need at least for your header/footer. \end_layout \begin_layout Subsection This example \end_layout \begin_layout Standard This example demonstrates what can be done with custom header/footers. Don't use it for your document as it is just an example.

You obtain prettier results if you install the program \family typewriter pnmcrop \family default from the \family typewriter netpbm \family default package; for \SpecialChar LyX on Windows this program and also the \SpecialChar LaTeX -package are automatically installed together with \SpecialChar LyX . \end_layout \begin_layout Subsection Enabling previews \end_layout \begin_layout Standard If you would for example like to see in \SpecialChar LyX your math formulas typeset by \SpecialChar LaTeX , activate the option \family sans Display \begin_inset space ~ \end_inset Graphics \family default in the \family sans Tools\SpecialChar menuseparator Preferences \family default dialog under \family sans Look \begin_inset space ~ \end_inset and \begin_inset space ~ \end_inset feel\SpecialChar menuseparator Display \family default . Then set \family sans Instant \begin_inset space ~ \end_inset Preview \family default to \family sans On \family default . The \family sans Preview \begin_inset space ~ \end_inset Size \family default is the multiplication factor for the size. \end_layout \begin_layout Standard If you would like to see everything but your math formulas typeset by \SpecialChar LaTeX , set \family sans Instant \begin_inset space ~ \end_inset Preview \family default to \family sans No \begin_inset space ~ \end_inset math \family default . \end_layout \begin_layout Standard Previews are generated when you load a document into \SpecialChar LyX and when you finish editing an inset. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Previews of an already loaded document are not in every case immediately generated by activating the option \family sans Display \begin_inset space ~ \end_inset Graphics \family default . Reopening the document will fix such problems. \end_layout \end_inset \end_layout \begin_layout Subsection Selected document parts \end_layout \begin_layout Standard Besides math there are other cases where you might like to see a preview, for example things that \SpecialChar LyX cannot render like rotated parts or things that are not yet supported by \SpecialChar LyX . To do this, insert a preview inset via the menu \family sans Insert\SpecialChar menuseparator Preview \family default . Insert or paste the stuff that you want to preview into this inset. The preview will be generated when the cursor is outside the preview inset. If you click on the preview, you can edit the previewed stuff. \end_layout \begin_layout Standard An example: To create rotated boxes, you use the \SpecialChar LaTeX command \series bold \backslash rotatebox \series default which is not yet supported by \SpecialChar LyX . \begin_inset Foot status collapsed \begin_layout Plain Layout \series bold \backslash rotatebox \series default is explained in section \emph on Rotated and Scaled Boxes \emph default of the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual. \end_layout \end_inset Instead of the \SpecialChar TeX Code boxes you want to see in \SpecialChar LyX the final rotated boxes, for example to adjust the rotation angle to fit with the surrounding text. Therefore you create a preview inset and copy the text with the rotated boxes into it. Here is the result: \end_layout \begin_layout Standard \begin_inset Preview \begin_layout Standard This is a line \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash rotatebox[origin=r]{-60}{ \end_layout \end_inset \begin_inset Box Doublebox position "c" hor_pos "c" has_inner_box 0 inner_pos "c" use_parbox 0 use_makebox 0 width "1in" special "width" height "1in" height_special "totalheight" thickness "0.4pt" separation "3pt" shadowsize "4pt" framecolor "black" backgroundcolor "none" status collapsed \begin_layout Plain Layout with rotated \end_layout \end_inset \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset framed text \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash rotatebox[origin=lb]{60}{ \end_layout \end_inset \begin_inset Formula $\int A\,\mathrm{d}x=B$ \end_inset \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset and a formula. \end_layout \end_inset \end_layout \begin_layout Standard Previewing works also for colors. In this example a special framed, colored box was created using the \SpecialChar LaTeX command \series bold \backslash fcolorbox \series default : \begin_inset Foot status collapsed \begin_layout Plain Layout \series bold \backslash fcolorbox \series default is explained in section \emph on Colored Boxes \emph default of the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual. \end_layout \end_inset \end_layout \begin_layout Standard \begin_inset Preview \begin_layout Standard \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash fboxrule 1mm \backslash fboxsep 1mm \end_layout \end_inset \begin_inset ERT status collapsed \begin_layout Plain Layout \backslash fcolorbox{cyan}{magenta}{ \end_layout \end_inset This is text within a colored, framed box. \begin_inset ERT status collapsed \begin_layout Plain Layout } \end_layout \end_inset \end_layout \end_inset \end_layout \begin_layout Standard \begin_inset VSpace medskip \end_inset \end_layout \begin_layout Standard If \SpecialChar LyX does not show a preview, make sure that you enabled previews as described above and also make sure that \SpecialChar TeX Code in the preview inset is valid and that you loaded the \SpecialChar LaTeX packages in your document preamble that are required by the \SpecialChar TeX Code. If \SpecialChar LyX cannot create a preview, you will in most cases also not be able to view your document due to \SpecialChar LaTeX errors. So if you have to use some \SpecialChar TeX Code and don't know if it is correct, the preview inset is a nice method to check it without the need to view the whole document. \end_layout \begin_layout Subsection \SpecialChar LaTeX source code \end_layout \begin_layout Standard You can preview the \SpecialChar LaTeX source of the whole document or parts of it. Use the menu \family sans View\SpecialChar menuseparator Source \begin_inset space ~ \end_inset Pane \family default and a window will be shown where you can see the \SpecialChar LaTeX -source code. The window shows the source of the whole paragraph in which the cursor currently sits. You can also select document parts in \SpecialChar LyX 's main window, then only this selection (when it is more than one paragraph) is shown as source code. To view the whole document as source, enable the corresponding option in the source view window. If you check \family sans Automatic update \family default , you can see the changes as you make them in \SpecialChar LyX ; but note that if you have several documents open, this will slow things down as \SpecialChar LyX updates them all, not just the one which is open at the time. \end_layout \begin_layout Section Advanced Find and Replace \begin_inset CommandInset label LatexCommand label name "sec:Advanced-Find-and" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Replace \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Find \end_layout \end_inset \end_layout \begin_layout Subsection Introduction \end_layout \begin_layout Standard The advanced find and replace feature of \SpecialChar LyX allows for searching of complex, format-sensitive text segments and mathematics contents within \SpecialChar LyX documents. It is an enhancement of the standard (quick) find and replace feature. The key-features are: \end_layout \begin_layout Itemize Both searching of text and of mathematical formulas is allowed, where the latter is done by entering mathematics in the usual way; not only entire mathematical formulas are found, but also parts occurring within more complex formulas \end_layout \begin_layout Itemize Search may be format-insensitive, so that the searched text is found in any context/style (standard text, section headings, notes, and even mathematics ), or it may be format-sensitive, so that, for example, a word entered with a section heading will only be found within section headings \end_layout \begin_layout Itemize Search may be restricted to mathematics environments only; this is useful for remangling math notation where one does not want to match any text outside of mathematics environments \end_layout \begin_layout Itemize Search may be widened to a specific \emph on scope \emph default , i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space ~ \end_inset a set of files which may be all the children of the document being edited, all the open files, or all the manuals available from the \family sans Help \family default menu \end_layout \begin_layout Itemize Replace may optionally preserve capitalization, so that the replaced text capitalization is adapted to the matching text (i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space ~ \end_inset all lowercase, all uppercase, first letter uppercase followed by lowercase) \end_layout \begin_layout Subsection Basic usage \end_layout \begin_layout Standard The advanced find and replace feature is activated through the menu \family sans Edit\SpecialChar menuseparator Find & Replace \noun on ( \noun default Advanced \noun on ) \family default \noun default (shortcut \begin_inset Info type "shortcut" arg "dialog-show findreplaceadv" \end_inset ) or the toolbar button \begin_inset Info type "icon" arg "dialog-toggle findreplaceadv" \end_inset . This opens the \family sans Advanced Find and Replace \family default dialog. \end_layout \begin_layout Subsubsection Searching for text \end_layout \begin_layout Standard Enter into the \family sans Find \family default \SpecialChar LyX mini-editor a simple word, and search for occurrences of it by clicking on the \family sans Find \begin_inset space ~ \end_inset Next \family default button at the bottom of the dialog (or just press the \begin_inset Info type "shortcut" arg "paragraph-break" \end_inset key). The entered word is found both in text mode and in math mode, and in emphasized , bold or normal face, and in both in section titles and in standard text. Pressing \begin_inset Info type "shortcut" arg "paragraph-break" \end_inset repeatedly keeps searching forward while pressing \family sans Shift+Return \family default searches backwards. \end_layout \begin_layout Standard The \family sans Case \begin_inset space ~ \end_inset sensitive \family default option allows matches to occur only with the same case as entered in the \family sans Find \family default editor. The \family sans Whole \begin_inset space ~ \end_inset words \family default option allows matches to occur only at word boundaries. \end_layout \begin_layout Subsubsection Searching for mathematics \end_layout \begin_layout Standard Mathematical formulas, such as \begin_inset Formula $x^{2}$ \end_inset or something more complex like \begin_inset Formula $\frac{x^{2}}{1+x^{2}}$ \end_inset , may be searched for by typing them in the \family sans Find \family default editor. When searching for a formula, it is found both when it is alone and when it occurs in sub-formulas and nested parts of sub-formulas. For example the mentioned segments would be found in something like \begin_inset Formula $\frac{x^{2}}{\sqrt{\frac{x^{2}}{1+x^{2}}}}$ \end_inset . \end_layout \begin_layout Subsubsection Style-aware search \end_layout \begin_layout Standard It is also possible to search for text with specific styles. This is done by switching to the \family sans Settings \family default tab of the dialog and unchecking the \family sans Ignore format \family default option. This way, entering in the \family sans Find \family default editor \end_layout \begin_layout Itemize a normal word and searching for it would not find instances of the word occurring in emphasized or boldface. \end_layout \begin_layout Itemize an emphasized or boldface word and searching for it would find the respective instances with the same face only, and within the same text style only. \end_layout \begin_layout Itemize a normal word in a section heading, and searching for it, would find occurrences of it only within section headings. Also, if the text to search is given an emphasized or bold face, in addition to a section style, then it is found only when occurring with the same style. \end_layout \begin_layout Itemize a displayed formula will only find instances of this formula that are also displayed formulas (and not inline formulas). \end_layout \begin_layout Subsubsection Replace \end_layout \begin_layout Standard The entries made in the \family sans Find \family default editor can be replaced with entries made in the \family sans Replace \begin_inset space ~ \end_inset with \family default editor. In order to find the next occurrence and replace it, click on the \family sans Replace \family default button or alternatively press \begin_inset Info type "shortcut" arg "paragraph-break" \end_inset or \family sans Shift+Return \family default while the cursor is in the \family sans Replace \begin_inset space ~ \end_inset with \family default editor. \end_layout \begin_layout Standard You can replace with fully-featured formatted \SpecialChar LyX entries. Typical scenarios in which to use this capability might be (just to mention two): \end_layout \begin_layout Itemize replacing occurrences of a word with a customized formatted version of the same word, for example replacing occurrences of a name like \begin_inset Quotes eld \end_inset func() \begin_inset Quotes erd \end_inset with its typewriter version \begin_inset Quotes eld \end_inset \family typewriter func() \family default \begin_inset Quotes erd \end_inset \end_layout \begin_layout Itemize performing a notation rework of mathematical symbols, for example replacing occurrences of \begin_inset Quotes eld \end_inset \begin_inset Formula $R$ \end_inset \begin_inset Quotes erd \end_inset with \begin_inset Quotes eld \end_inset \begin_inset Formula $\mathbb{R}$ \end_inset \begin_inset Quotes erd \end_inset (you may want to enable the \family sans Whole \begin_inset space ~ \end_inset words \family default and \family sans Case \begin_inset space ~ \end_inset sensitive \family default options and disable the \family sans Ignore format \family default option in the \family sans Settings \family default tab, in order to avoid replacing all \begin_inset Quotes eld \end_inset R \begin_inset Quotes erd \end_inset letters occurring in normal text), or occurrences of \begin_inset Formula $x_{j}^{i}$ \end_inset with \begin_inset Formula $x_{i,\,j}$ \end_inset , or occurrences of \begin_inset Formula $x[k]$ \end_inset with \begin_inset Formula $x_{k}$ \end_inset . \end_layout \begin_layout Subsection Advanced usage \end_layout \begin_layout Standard There is a regular expression (regexp) based searching facility. \begin_inset Foot status collapsed \begin_layout Plain Layout A good explanation of regular expressions is given in this Wikipedia entry: \begin_inset CommandInset href LatexCommand href target "https://en.wikipedia.org/wiki/Regular_expression" literal "false" \end_inset . \end_layout \end_inset You can search for a regular expression by inserting a regexp inset into the \family sans Find \family default editor. This is done with the context menu \family sans Insert\SpecialChar menuseparator Insert Regular Expression \family default while the cursor is in the \family sans Find \family default editor. Characters entered within regexp insets are matched according to the regular expression matching rules \begin_inset Foot status collapsed \begin_layout Plain Layout Under the constraint that any (sub)expression must match a well-formed \SpecialChar LyX segment, i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space ~ \end_inset when matching \SpecialChar LaTeX code, no segments with unbalanced {} braces are allowed to match expressions. \end_layout \end_inset , while text entered outside regexp insets is matched exactly against the same text in the document. You can cut and paste regexp-mode insets. Examples of using such a feature may be: \end_layout \begin_layout Enumerate Searching for all fractions with a given denominator: for example, entering in the \family sans Find \family default editor the fraction \begin_inset Formula $\frac{.*}{1+x^{2}}$ \end_inset (where the \begin_inset Formula $.*$ \end_inset on the numerator is the match-everything regular expression) finds all fractions with the given denominator. \end_layout \begin_layout Enumerate Searching for all text with a given style: for example, after unchecking the \family sans Ignore format \family default option from the \family sans Settings \family default tab, entering a \series bold \begin_inset Formula $.*$ \end_inset \series default regular expression and giving it an emphasized or bold face, finds all emphasized or bold face text respectively. Also, by inserting a \begin_inset Formula $.*$ \end_inset regular expression in a bullet or enumerated list or a section heading, you can find all bullet or enumerated lists or section headings. \end_layout \begin_layout Standard Finally, references to (sub)expressions in regexp may be used as usual: Enclosing parts of the expression within round braces \begin_inset Formula $()$ \end_inset , and referring back to them through \begin_inset Formula $\backslash1$ \end_inset , \begin_inset Formula $\backslash2$ \end_inset , etc.. For example, try searching with the regexp \begin_inset Newline newline \end_inset [[:space:]]([[:alpha:]]+)[[:space:]] \backslash 1[[:space:]] \begin_inset Newline newline \end_inset in order to find word repetitions, if there are any. \end_layout \begin_layout Standard The usage of back references in the replaced text is not (yet) implemented. \end_layout \begin_layout Standard \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default Back references work both when occurring within the same regexp, and when occurring in multiple different regexps, where the numbering of back-referenced sub-expressions is absolute. That is, \begin_inset space ~ \end_inset \begin_inset Formula $\backslash1$ \end_inset always refers to the first occurrence of \begin_inset Formula $()$ \end_inset in all entered regexps. \end_layout \end_inset \end_layout \begin_layout Section Spell Checking \begin_inset CommandInset label LatexCommand label name "sec:Spellchecking" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Spell checking \end_layout \end_inset \end_layout \begin_layout Standard \SpecialChar LyX has a built-in spell checker. The menu \family sans Tools\SpecialChar menuseparator Spellchecker \family default , the \family sans F7 \family default key or the toolbar button \begin_inset Info type "icon" arg "dialog-show spellchecker" \end_inset start the spell checking from either the current cursor position or the beginning of the currently selected text. A sidebar will appear showing any incorrect (or unknown) word found, allowing you to edit and replace it in a second line. Whenever an unknown word is found, the word is highlighted and the text scrolled so that it is visible. In the spellchecker sidebar, there is a box showing suggestions for a correctio n, if any could be found. Clicking on one of the corrections will copy it to the \family sans Replacement \family default field, double-clicking directly invokes the replacement. Unknown but correctly typed words can be added to the personal dictionary. \end_layout \begin_layout Standard By default, the dictionary file used is determined by the document language that is set in the \family sans Document\SpecialChar menuseparator Settings \family default dialog. You can specify the language of a word in the spellchecker dialog by choosing a different one at the top of the dialog. \SpecialChar LyX can correctly spell check documents containing multiple languages. This works if you have set the language of the text parts using the \family sans Text \begin_inset space ~ \end_inset Style \family default dialog ( \begin_inset Info type "icon" arg "dialog-show character" \end_inset ) and have the spell checker dictionaries installed. \SpecialChar LyX automatically switches to the appropriate dictionary file. \end_layout \begin_layout Standard All spell-checker dictionaries supported by \SpecialChar LyX can be downloaded from here: \begin_inset Newline newline \end_inset \begin_inset Flex URL status collapsed \begin_layout Plain Layout https://sourceforge.net/projects/lyxwininstaller/files/hunspell/ \end_layout \end_inset \begin_inset Newline newline \end_inset There are 2 \begin_inset space ~ \end_inset files for each language. To install a dictionary on Windows, copy the 2 \begin_inset space ~ \end_inset files into \SpecialChar LyX 's installation subfolder \family sans ~ \backslash Resources \backslash dicts \family default and restart \SpecialChar LyX . \begin_inset Newline newline \end_inset With Linux one needs to install the packages for the desired language. The number of these packages vary depending on the Linux distribution, but in most cases these are \family typewriter aspell-xx \family default , \family typewriter hunspell-xx \family default , \family typewriter myspell-xx \family default , etc., where \family sans xx \family default is the language code. \end_layout \begin_layout Subsection Further Settings \end_layout \begin_layout Standard In the menu \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Language \begin_inset space ~ \end_inset Settings\SpecialChar menuseparator Spellchecker \family default you can set the following things: \end_layout \begin_layout Description Spellchecker \begin_inset space ~ \end_inset engine Select the library \SpecialChar LyX should use for spell checking. Depending on your platform, \family typewriter hunspell \family default or \family typewriter enchant \begin_inset Foot status collapsed \begin_layout Plain Layout Enchant itself is a wrapper library having different configurable back-ends. Please consult the documentation or man-page of it to learn more. \end_layout \end_inset \family default are available. On Windows only \family typewriter hunspell \family default is available. \SpecialChar LyX on Mac \begin_inset space ~ \end_inset OS can also use Mac's own spellchecker and will use it by default. \end_layout \begin_layout Description Alternative \begin_inset space ~ \end_inset language If this field is not empty, \SpecialChar LyX will always use the given language for the spell checking, no matter what the document language is. \end_layout \begin_layout Description Escape \begin_inset space ~ \end_inset characters Allows you to add non-standard characters that the spell checker should escape, e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset German umlauts. This should normally not be needed. \end_layout \begin_layout Description Accept \begin_inset space ~ \end_inset compound \begin_inset space ~ \end_inset words Prevents the spell checker from complaining about compounded words like \begin_inset Quotes eld \end_inset passthrough \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Description Spellcheck \begin_inset space ~ \end_inset continuously Checks the spelling of your document as you type it. Misspelled words get underlined with a dotted red line. By right-clicking on an underlined word, suggestions from the spellchecker appear in a context menu. Choosing one of them will replace the misspelled word with the suggested word. \end_layout \begin_layout Description Spellcheck \begin_inset space ~ \end_inset notes \begin_inset space ~ \end_inset and \begin_inset space ~ \end_inset comments If enabled, the spelling of non-printed document content is checked as well. \end_layout \begin_layout Section Thesaurus \begin_inset Index idx status collapsed \begin_layout Plain Layout Thesaurus \end_layout \end_inset \begin_inset CommandInset label LatexCommand label name "sec:Thesaurus" \end_inset \end_layout \begin_layout Standard \SpecialChar LyX provides a multilingual thesaurus. It uses the same thesaurus framework as LibreOffice, OpenOffice and Firefox (namely the \family sans MyThes \family default \begin_inset Foot status collapsed \begin_layout Plain Layout \begin_inset CommandInset href LatexCommand href target "https://lingucomponent.openoffice.org/thesaurus.html" literal "false" \end_inset \end_layout \end_inset thesaurus library, which is included in \SpecialChar LyX ). Therefore, \SpecialChar LyX is able to directly access OpenOffice thesaurus dictionaries, which are available for many languages. \end_layout \begin_layout Standard This section describes how new dictionaries are installed and set up for the use with \SpecialChar LyX . \end_layout \begin_layout Subsection Setting up the thesaurus \end_layout \begin_layout Standard The \family sans MyThes \emph on / \emph default OpenOffice \family default thesauri consist of two files per language: A file with the suffix \emph on *.dat \emph default containing the data and an index file with the suffix \emph on *.idx \emph default . The standardized file names include the language code for the given language (e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space ~ \end_inset \family sans en_US \family default for US English). For instance, the US English files are named: \end_layout \begin_layout Itemize th_en_EN_v2.idx \end_layout \begin_layout Itemize th_en_EN_v2.dat \end_layout \begin_layout Standard If you have \family sans LibreOffice \family default or \family sans OpenOffice \family default and its thesaurus installed, these files should be already on your system and you just need to point \SpecialChar LyX (in \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Paths\SpecialChar menuseparator Thesaurus \begin_inset space ~ \end_inset dictionaries \family default ) to the path where they are installed. \begin_inset Foot status collapsed \begin_layout Plain Layout On Linux, depending on your distribution and the way you installed the dictionar ies, typical locations are \family typewriter /usr/share/mythes/ \family default , \family typewriter /usr/share/myspell/dicts/ \family default , \family typewriter /usr/share/ooo/thesaurus/ \family default , \family typewriter ~/.config/libreoffice//user/ \family default or alike.

On the Mac, the default location is \family typewriter /Users\SpecialChar breakableslash \SpecialChar breakableslash Library\SpecialChar breakableslash Application Support\SpecialChar breakableslash libreoffice\SpecialChar breakableslash \SpecialChar breakableslash user \family default /. \end_layout \end_inset On Windows, you can alternatively also select dictionaries for installation during the \SpecialChar LyX installation process, which will then be installed in the correct place right away. \end_layout \begin_layout Standard If you want to install new\SpecialChar breakableslash further thesaurus dictionaries, you can downloaded them from here: \begin_inset Newline newline \end_inset \begin_inset Flex URL status collapsed \begin_layout Plain Layout https://sourceforge.net/projects/lyxwininstaller/files/thesaurus/ \end_layout \end_inset \end_layout \begin_layout Standard To install a new dictionary, download the two files for this dictionary into the thesaurus path (which is set in \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Paths\SpecialChar menuseparator Thesaurus \begin_inset space ~ \end_inset dictionaries \family default ) and restart \SpecialChar LyX . If this path is not defined yet, you can use a dictionary of your choice and point \SpecialChar LyX there. \end_layout \begin_layout Standard Alternatively, you can also install new dictionaries via \family sans LibreOffice\SpecialChar breakableslash OpenOffice \family default or, on Linux, via your package manager (look for \emph on mythes-* \emph default or \emph on libreoffice-thesaurus-* \emph default packages). If you do this, make sure that \SpecialChar LyX is able to find the installed dictionaries, i. \begin_inset space \thinspace{} \end_inset e. that \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Paths\SpecialChar menuseparator Thesaurus \begin_inset space ~ \end_inset dictionaries \family default points to the path where you installed these dictionaries. \end_layout \begin_layout Subsection Using the thesaurus \end_layout \begin_layout Standard To start the thesaurus, use the menu \family sans Tools\SpecialChar menuseparator Thesaurus \family default or the toolbar button \begin_inset Info type "icon" arg "thesaurus-entry" \end_inset while the cursor is at the word you want to look up or while a word is selected. A dialog pops up showing you probably related words that you can use as a replacement. The suggestions are grouped into categories. Note that, for some languages (such as English), the thesaurus does not only show equivalent words (synonyms), but also generic terms (such as \emph on organism \emph default for \emph on plant \emph default ), related terms (such as \emph on political \begin_inset space ~ \end_inset theory \emph default for \emph on anarchistic \emph default ), compounds (such as \emph on tree \begin_inset space ~ \end_inset diagram \emph default , if you look for \emph on tree \emph default ) and opposites (antonyms) (such as \emph on girl \emph default for \emph on boy \emph default ). Generic terms, related terms and antonyms are marked as such. \end_layout \begin_layout Standard The language is automatically chosen from the language at the cursor, but you can also switch it in the dialog, as you can enter new words to look up directly there. \end_layout \begin_layout Standard Note that the thesaurus cannot handle phrases (only compounds that are in the dictionary, such as the above \emph on tree diagram \emph default ), and you have to use the so called lemma form, i. \begin_inset space \thinspace{} \end_inset e. \begin_inset space \space{} \end_inset the form that is used in the dictionaries (for many languages: first person singular indicative active for nouns, infinitive for verbs). For example, looking up the word form \emph on reporting \emph default yields no results, while results are shown for the word form \emph on report \emph default . Your best bet is to highlight only the relevant part of such a word (e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset \emph on report \emph default in \emph on report \emph default s); then you will get suggestions without needing to adjust the query in the dialog, and also the replacement will probably be correct (as only the highlighted part will be replaced; thus the ending remains). \end_layout \begin_layout Section Change Tracking \begin_inset Index idx status collapsed \begin_layout Plain Layout Change Tracking \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Document !

For example, if you want to write in Italian, you can configure \SpecialChar LyX to use an Italian keymap. The \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Editing\SpecialChar menuseparator Keyboard/Mouse \family default dialog allows you to choose up to two keyboard mappings, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Keyboard-Map" \end_inset . You can choose primary and secondary keyboard languages and then select which one you want to use. \end_layout \begin_layout Standard Finally, you may just want to change a few key mappings or create an entirely different keymap (for Vulcan, for instance). You may, for example, normally write in Italian on a U. \begin_inset space \thinspace{} \end_inset S.-style keyboard but want to include an occasional quotation in German. In such a case, you can write your own keyboard mapping or modify an existing one to support the characters you want.

This will create a template named \family typewriter defaults.lyx \family default which is automatically loaded by \SpecialChar LyX when you create a new document without using a template. \end_layout \begin_layout Standard The button \family sans Use Class Defaults \family default resets the document settings to the default of the document class. This affects mostly class options, the page layout and Numbering & TOC. \end_layout \begin_layout Standard The different submenus of the dialog are explained in the following sections. There are so many document settings available that it might take a while to find the one you are looking for. To find a setting quicker, you can use the search field which is above the submenus of the dialog. If you search e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset for \begin_inset Quotes eld \end_inset page \begin_inset Quotes erd \end_inset , you will see that some submenus will be grayed-out and disabled. Only the submenus with page settings stay enabled. The found page settings are labeled red in these submenus. \end_layout \begin_layout Section Document Class \end_layout \begin_layout Standard Here you set the document class, class options, a graphics driver, and a master document. Document classes are described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Document-Classes" \end_inset . \end_layout \begin_layout Standard With the button \family sans Local \begin_inset space ~ \end_inset Layout \family default you can load you own layout-file, that is not in \SpecialChar LyX 's \emph on layouts \emph default folder and thus not recognized by \SpecialChar LyX as a layout for a document class. For more about layout-files, see the chapter \emph on Installing New Document Classes, Types of Layout Files \emph default of the \emph on Customization \emph default Handbook. \end_layout \begin_layout Standard Some classes use special class options by default. If this is the case, they are listed in the field \family sans Predefined \family default and you can decide to use them or not. If you do not know exactly what the default class options are for, it is recommended you leave them untouched. The \family sans Graphics driver \family default is used for \SpecialChar LaTeX 's graphics, color and page layout packages. If using \family sans Default \family default , the default driver for the \SpecialChar LaTeX -packages is used. It is recommended that you use the default unless you know what you are doing. \begin_inset Foot status collapsed \begin_layout Plain Layout When you want to use one of the following drivers \begin_inset Newline newline \end_inset \family sans dvi2ps, dvialw, dvilaser, dvitops, psprint, pubps, ln \family default \begin_inset Newline newline \end_inset you first have to activate them in your \SpecialChar LaTeX distribution, see section \emph on Driver support \emph default in \begin_inset CommandInset href LatexCommand href target "https://www.ctan.org/tex-archive/macros/latex/required/graphics/grfguide.pdf" literal "false" \end_inset . \end_layout \end_inset \end_layout \begin_layout Standard Specifying a \family sans Master \family default document is necessary if the current document is a child or subdocument. The master document will be used by \SpecialChar LyX in the background if the child document is opened without its master. This way child documents are always compilable. More about master and child documents is explained in the section \emph on Child Documents \emph default of the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual. \end_layout \begin_layout Standard There is also an option to suppress the date and one to use the \SpecialChar LaTeX -package \series bold refstyle \series default instead of \series bold prettyref \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! prettyref \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! refstyle \end_layout \end_inset for cross-references, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Cross-References" \end_inset . \end_layout \begin_layout Section Child Documents \end_layout \begin_layout Standard This submenu is only visible when your document includes child documents.

The \family sans Line \begin_inset space ~ \end_inset spacing \family default and whether it should be a \family sans Two-column \begin_inset space ~ \end_inset document \family default can also be specified here. \end_layout \begin_layout Standard Note that \SpecialChar LyX will not show two columns or the specified line spacing on screen. That would be impractical, often unreadable, and is not part of the WYSIWYM concept. However, it will be as you specified in the output. \end_layout \begin_layout Standard With the option \family sans Use justification in \SpecialChar LyX work area \family default you can decide if \SpecialChar LyX justifies the text on screen. This only affects the text inside \SpecialChar LyX not in the output. \end_layout \begin_layout Section Page Layout \end_layout \begin_layout Standard This dialog is described in sections \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Paper-Size,-Orientation" \end_inset and \begin_inset CommandInset ref LatexCommand ref reference "subsec:Document-Layout" \end_inset . \end_layout \begin_layout Section Page Margins \end_layout \begin_layout Standard Here you can adjust the page margins as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Margins" \end_inset . \end_layout \begin_layout Section Language \begin_inset CommandInset label LatexCommand label name "sec:Language-encodings" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Language ! Encoding \end_layout \end_inset \end_layout \begin_layout Standard The document language and quote styles are set here. The encoding specifies how the document content is exported to \SpecialChar LaTeX (the \SpecialChar LyX file is always encoded in utf8). All characters that cannot be encoded using the specified encoding will be exported as \SpecialChar LaTeX -commands (this can fail if a \SpecialChar LaTeX -command is not known for a particular character). \end_layout \begin_layout Standard If you use the option \family sans Language Default \family default , \SpecialChar LyX determines the encoding of a text part from the language of this text. If the document contains text in more than one language you may get more than one encoding in the \SpecialChar LaTeX file. If you do not use this option then the complete document will always use exactly one encoding. Checking this option is the preferred setting. \end_layout \begin_layout Standard \SpecialChar LyX also supports Unicode output, which is particularly useful if you need lots of special symbols or non-alphabetic scripts, respectively. If you want to use this (and your \SpecialChar LaTeX installation supports Unicode), choose one of the four utf8 variants from the list below. Unfortunately the Unicode support of standard \SpecialChar LaTeX is quite incomplete, so it is not uncommon that a file with lots of Unicode symbols works fine with \family sans Language Default \family default (when \SpecialChar LyX uses its list of known \SpecialChar LaTeX -commands), but does not work with a fixed utf8 encoding (when the list of known \SpecialChar LaTeX -commands is not used, because all Unicode symbols can be encoded in utf8). The situation is much better with Xe\SpecialChar TeX and Lua\SpecialChar TeX , two new alternative engines to standard \SpecialChar LaTeX . Both engines support Unicode natively. \SpecialChar LyX now also supports these two engines (via the output formats \family sans PDF \begin_inset space ~ \end_inset (XeTeX) \family default , \family sans PDF \begin_inset space ~ \end_inset (LuaTeX) \family default and \family sans DVI \begin_inset space ~ \end_inset (LuaTeX) \family default , see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Output-file-formats" \end_inset ). So if you are using many special or accented characters and \family sans Language Default \family default fails, you might try out one of these new engines. \end_layout \begin_layout Standard The \family sans Language \begin_inset space ~ \end_inset package \family default determines the \SpecialChar LaTeX -package that is used for hyphenation and the translation of strings like \begin_inset Quotes eld \end_inset Part \begin_inset Quotes erd \end_inset . The possible settings are: \end_layout \begin_layout Description Default uses the language package that is selected in \family sans Tools\SpecialChar menuseparator Preferences\SpecialChar menuseparator Language Settings \family default (see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Prefs-Language" \end_inset ). \end_layout \begin_layout Description Automatic selects the most suitable language package for the view/export format you will use. In many cases this will be \series bold babel \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! babel \end_layout \end_inset . If the newer package \series bold polyglossia \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! polyglossia \end_layout \end_inset is more appropriate (is the case when using Xe\SpecialChar TeX or Lua\SpecialChar TeX and non-\SpecialChar TeX fonts), this package will be used instead of \series bold babel \series default . \end_layout \begin_layout Description Always \begin_inset space ~ \end_inset Babel uses \series bold babel \series default even if \series bold polyglossia \series default would be more appropriate. \end_layout \begin_layout Description Custom allows you to specify a language package command of your choice. For example if you want to use a language-specific package like \series bold ngerman \series default (for German texts), type in \series bold \begin_inset Newline newline \end_inset \backslash usepackage{ngerman} \end_layout \begin_layout Description None will not use a language package. This is necessary for some document classes for scientific articles. \end_layout \begin_layout Standard Here is a list with the important encodings: \end_layout \begin_layout Description Language \begin_inset space ~ \end_inset Default \begin_inset space ~ \end_inset (no \begin_inset space ~ \end_inset inputenc) Same as \family sans Language Default \family default , but the \SpecialChar LaTeX -package \series bold inputenc \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! inputenc \end_layout \end_inset is not used. When using this, you probably need to load some additional packages manually in the preamble and specify the used encoding for text parts in foreign languages in \SpecialChar TeX code. \end_layout \begin_layout Description ASCII the ASCII encoding, covers only plain English (7-bit ASCII). \SpecialChar LyX converts all other characters into \SpecialChar LaTeX commands, which may result in a big file when lots of \SpecialChar LaTeX -commands are needed. \end_layout \begin_layout Description Arabic \begin_inset space ~ \end_inset (CP \begin_inset space ~ \end_inset 1256) MS Windows code page for Arabic and Farsi \end_layout \begin_layout Description Arabic \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-6) for Arabic and Farsi \end_layout \begin_layout Description Armenian \begin_inset space ~ \end_inset (ArmSCII8) for Armenian \end_layout \begin_layout Description Baltic \begin_inset space ~ \end_inset (CP \begin_inset space ~ \end_inset 1257) MS Windows code page for Estonian, Latvian and Lithuanian, the same as the ISO-8859-13 encoding \end_layout \begin_layout Description Baltic \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-13) for Estonian, Latvian and Lithuanian, a superset of the ISO-8859-4 encoding \end_layout \begin_layout Description Baltic \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-4) (latin 4) for Estonian, Latvian and Lithuanian, a subset of the ISO-8859-13 encoding \end_layout \begin_layout Description Central \begin_inset space ~ \end_inset European \begin_inset space ~ \end_inset (CP \begin_inset space ~ \end_inset 1250) MS Windows code page for ISO \begin_inset space ~ \end_inset 8859-2 (latin2) \end_layout \begin_layout Description Central \begin_inset space ~ \end_inset European \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-2) (latin 2) covers Albanian, Croatian, Czech, German, Hungarian, Polish, Romanian, Slovak and Slovenian \end_layout \begin_layout Description Chinese \begin_inset space ~ \end_inset (simplified) \begin_inset space ~ \end_inset (EUC-CN) for simplified Chinese, used especially on UNIX OSes, since 2001 this encoding is officially replaced by the encoding GB18030, as GB18030 is not available for \SpecialChar LaTeX you should try to use the encoding Unicode \begin_inset space ~ \end_inset (CJK) \begin_inset space ~ \end_inset (utf8) \end_layout \begin_layout Description Chinese \begin_inset space ~ \end_inset (simplified) \begin_inset space ~ \end_inset (GBK) for simplified Chinese, is the same as the Windows code page CP 936 except for the Euro currency sign, since 2001 this encoding is officially replaced by the encoding GB18030, as GB18030 is not available for \SpecialChar LaTeX you should try to use the encoding Unicode \begin_inset space ~ \end_inset (CJK) \begin_inset space ~ \end_inset (utf8) \end_layout \begin_layout Description Chinese \begin_inset space ~ \end_inset (traditional) \begin_inset space ~ \end_inset (EUC-TW) for traditional Chinese \end_layout \begin_layout Description Cyrillic \begin_inset space ~ \end_inset (CP \begin_inset space ~ \end_inset 1251) MS Windows code page for Cyrillic \end_layout \begin_layout Description Cyrillic \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-5) covers Belorussian, Bulgarian, Macedonian, Serbian and Ukrainian \end_layout \begin_layout Description Cyrillic \begin_inset space ~ \end_inset (KOI8-R) standard Cyrillic especially for Russian \end_layout \begin_layout Description Cyrillic \begin_inset space ~ \end_inset (KOI8-U) Cyrillic for Ukrainian \end_layout \begin_layout Description Cyrillic \begin_inset space ~ \end_inset (pt \begin_inset space ~ \end_inset 154) Cyrillic for Kazakh \end_layout \begin_layout Description Greek \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-7) for Greek \end_layout \begin_layout Description Hebrew \begin_inset space ~ \end_inset (CP \begin_inset space ~ \end_inset 1255) MS Windows code page for Hebrew, a superset of the ISO-8859-8 encoding \end_layout \begin_layout Description Hebrew \begin_inset space ~ \end_inset (ISO \begin_inset space ~ \end_inset 8859-8) for Hebrew \end_layout \begin_layout Description Japanese \begin_inset space ~ \end_inset (CJK) \begin_inset space ~ \end_inset (EUC-JP) EUC-JP encoding for Japanese, uses the \SpecialChar LaTeX -package \series bold CJK \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages !

If you use \SpecialChar LyX in a certain language, \SpecialChar LyX will try to use the appropriate binding file. \end_layout \begin_layout Standard Some binding files, like \shape italic math.bind \shape default , only have a limited scope. When looking at the end of the file \shape italic cua.bind \shape default , you can see that they are included to keep the overview in the bind-file. \end_layout \begin_layout Standard The field \family sans Show \begin_inset space ~ \end_inset key-bindings \begin_inset space ~ \end_inset containing \family default allows you to search for the shortcut provided for a particular function in the selected key binding file. \end_layout \begin_layout Subsubsection Editing Shortcuts \begin_inset CommandInset label LatexCommand label name "subsec:Editing-Shortcuts" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Key Bindings ! Editing \end_layout \end_inset \end_layout \begin_layout Standard To add new or modify existing key bindings to your own taste you can use the table in the dialog that lists all \SpecialChar LyX functions and the bound shortcuts. To find functions easily, they are grouped by categories and the dialog provides the field \family sans Show key-bindings containing \family default . In this field you can insert a keyword for a function you want to edit. Insert there for example as keyword \begin_inset Quotes eld \end_inset paste \begin_inset Quotes erd \end_inset and you get the four different existing shortcuts for the three different functions that contain \begin_inset Quotes eld \end_inset paste \begin_inset Quotes erd \end_inset in their name. As you can see, one function can have more than one shortcut. All \SpecialChar LyX functions are also listed in the file \family sans \SpecialChar LyX Functions \family default that you will find in the \family sans Help \family default menu. \end_layout \begin_layout Standard For example, to add the shortcut \family sans Alt+Q \family default for the function \family sans textstyle-apply \family default , select the function and press the \family sans Modify \family default button. A dialog pops up where you can add the shortcut by using it. So press Alt+Q to define the shortcut. \end_layout \begin_layout Standard Modifying an existing shortcut is done the same way. You can also bind multiple functions to one shortcut by starting the \SpecialChar LyX Function definition with “command alternatives” and following it with the different function names as a semicolon separated list. \SpecialChar LyX will then use the first function that is enabled in the current document part. \end_layout \begin_layout Standard If you don't like a particular shortcut, you can remove it. \end_layout \begin_layout Standard Alternatively you can also edit shortcuts by modifying binding files with a text editor. The syntax of the entries is: \end_layout \begin_layout Standard \series bold \backslash bind \begin_inset Quotes eld \end_inset key combination \begin_inset Quotes erd \end_inset \begin_inset Quotes eld \end_inset \SpecialChar LyX function \begin_inset Quotes erd \end_inset \end_layout \begin_layout Standard Note, though, that the key combination definition uses a specific syntax. This applies to the designators of specific modifier keys (e. \begin_inset space \thinspace{} \end_inset g., \family typewriter M \family default , \family typewriter S \family default , \family typewriter C \family default for \family sans Meta/Alt \family default , \family sans Shift \family default , \family sans Ctrl \family default , respectively) as well as to the other keys. Note particularly that you cannot use non-alphanumeric characters directly in the definition of the key combination, but must use commands following the Xlib standard instead (please refer to the existing bind files for a model). So if you wanted to bind a command to the key combination \family sans Alt+Shift+: \family default , you needed to specify it as \family typewriter M-S-colon \family default . If you use the dialog to edit key bindings, you don't have to care for these specifics. \SpecialChar LyX transforms your input to the correct syntax. \end_layout \begin_layout Subsection Keyboard/Mouse \begin_inset CommandInset label LatexCommand label name "subsec:Keyboard-Map" \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Keyboard Map \end_layout \end_inset \begin_inset Index idx status collapsed \begin_layout Plain Layout Settings !

It is the default when you \family sans Open \family default , \family sans Save \family default or \family sans Save \begin_inset space ~ \end_inset As \family default files. \end_layout \begin_layout Description Document \begin_inset space ~ \end_inset templates This directory will be opened when you use the menu \family sans File\SpecialChar menuseparator New \begin_inset space ~ \end_inset from \begin_inset space ~ \end_inset Template \family default . \end_layout \begin_layout Description Example \begin_inset space ~ \end_inset files This directory will be opened when you use the button \family sans Examples \family default in the \family sans File\SpecialChar menuseparator Open \family default dialog. \begin_inset Newline newline \end_inset \begin_inset Note Greyedout status open \begin_layout Plain Layout \series bold Note: \series default The \family sans Examples \family default button does not exist when using \SpecialChar LyX on Mac OS and Windows systems. \end_layout \end_inset \end_layout \begin_layout Description Backup \begin_inset space ~ \end_inset directory \begin_inset Index idx status collapsed \begin_layout Plain Layout Backup ! Directory \end_layout \end_inset Backup copies will be saved to this directory. If no directory is given but backups are enabled as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Backup documents" \end_inset , the \family sans Working directory \family default will be used to save the backups. \begin_inset Newline newline \end_inset Backup files have the ending \begin_inset Quotes eld \end_inset .lyx~ \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Description LyXServer \begin_inset space ~ \end_inset pipe Here you can enter the name of a so-called UNIX-pipe. This pipe is used to send data from external programs to \SpecialChar LyX . \begin_inset Newline newline \end_inset \series bold Example: \series default You add a Bib\SpecialChar TeX database \emph on test.bib \emph default to your document. You can edit this file with the program \family typewriter JabRef \family default . In \family typewriter JabRef \family default you have to use the same Unix-Pipe for \SpecialChar LyX in its preferences under \family sans External \begin_inset space ~ \end_inset programs \family default . If you want to get one entry of the database as citation, select it in \family typewriter JabRef \family default and click on the \SpecialChar LyX symbol. The entry will now be inserted as a citation at the current cursor position in your \SpecialChar LyX file. Of course, \family typewriter JabRef \family default and \SpecialChar LyX need to be running the same time. \begin_inset Newline newline \end_inset The pipe is also used for the \family sans Single instance \family default feature, see section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "subsec:Backup documents" \end_inset . \begin_inset Newline newline \end_inset To use the \SpecialChar LyX Server-Pipe on Windows, you must use this pipe name: \begin_inset Newline newline \end_inset \series bold \backslash \backslash . \backslash pipe \backslash lyxpipe \end_layout \begin_layout Description Temporary \begin_inset space ~ \end_inset directory Temporary files will be saved in this directory. \end_layout \begin_layout Description Thesaurus \begin_inset space ~ \end_inset dictionary Directory where the thesaurus dictionaries are located. You only need to specify it if the thesaurus does not work or if you want to use custom/alternative dictionaries. \end_layout \begin_layout Description Hunspell \begin_inset space ~ \end_inset dictionary Directory where the dictionaries of the spell checker program \family typewriter Hunspell \family default are located. You only need to specify it if you are using \family typewriter Hunspell \family default and spell checking does not work or if you want to use custom/alternative dictionaries. For \SpecialChar LyX on Windows \family typewriter Hunspell \family default is the only available spell checker and should work without specifying a directory. \end_layout \begin_layout Description PATH \begin_inset space ~ \end_inset prefix This field contains a list of paths to external programs. When \SpecialChar LyX needs to use an external program, it looks in this list to see where to find it on the system. The path list is automatically set up on Windows and Mac systems when \SpecialChar LyX is configured; so you normally don't have to modify it. On Unix \begin_inset space \thinspace{} \end_inset / \begin_inset space \thinspace{} \end_inset Linux systems, the path list will need to be set only if there are external programs you wish to use that are not in your normal system path ($PATH). \end_layout \begin_layout Description TEXINPUTS \begin_inset space ~ \end_inset prefix The TEXINPUTS environment variable allows you to use external files which are included in a \SpecialChar LyX document via commands in \SpecialChar TeX code or in the document preamble. This prefix includes by default the document directory (represented by a single dot '.'). The prefix can contain any list of paths separated by the default separator of the OS (':' on UNIX like systems and ';' on Windows). If files are included, the paths listed in the TEXINPUTS prefix will be scanned for the input files. Note that any non-absolute path listed in the TEXINPUTS prefix is considered to be relative to the directory of your \SpecialChar LyX file. It is recommended that you always include '.' as one of the paths; otherwise compilation may fail for some documents. \end_layout \begin_layout Section Identity \end_layout \begin_layout Standard Here you can insert your \family sans Name \family default and \family sans E-mail \family default address. These will be used when you have enabled change tracking, as described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Change-Tracking" \end_inset , to mark changes you make as yours. \end_layout \begin_layout Section Language Settings \begin_inset Index idx status collapsed \begin_layout Plain Layout Language !

Language issues that are handled by this package include proper hyphenation as well as localization of dates and text strings such as \begin_inset Quotes eld \end_inset Chapter \begin_inset Quotes erd \end_inset and \begin_inset Quotes eld \end_inset Table \begin_inset Quotes erd \end_inset . The most widespread language package is \series bold babel \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! babel \end_layout \end_inset ; it is the default language package in classic \SpecialChar LaTeX . More recent typesetting engines such as Xe\SpecialChar TeX and Lua\SpecialChar TeX come with the alternative language package \series bold polyglossia \series default \begin_inset Index idx status collapsed \begin_layout Plain Layout \SpecialChar LaTeX packages ! polyglossia \end_layout \end_inset that is more suited to the multi-script support of these engines. Furthermore, there are also specific language packages for languages not covered by \series bold babel \series default . The available selections are described in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Language-encodings" \end_inset . \end_layout \begin_layout Description Command \begin_inset space ~ \end_inset start If a special \SpecialChar LaTeX -package is needed to write in a certain document language, you can here specify the command to start the package. An example is the start command \family sans \backslash begin{arabtext} \family default that is needed to write Arabic using the package \series bold Arab\SpecialChar TeX \series default , see \begin_inset CommandInset citation LatexCommand cite key "Arabic" literal "true" \end_inset . The default is the \series bold babel \series default command \family sans \backslash selectlanguage{$$lang} \family default . \end_layout \begin_layout Description Command \begin_inset space ~ \end_inset end Counterpart to \family sans Command start \family default . Some packages, like the default, don't have an end command since the start command toggles the package on and off. \end_layout \begin_layout Description Default \begin_inset space ~ \end_inset decimal \begin_inset space ~ \end_inset separator Defines the default decimal point for use in tables (decimal point alignment). \end_layout \begin_layout Description Default \begin_inset space ~ \end_inset length \begin_inset space ~ \end_inset unit Defines the unit that is used as default for lengths in \SpecialChar LyX 's dialogs. \end_layout \begin_layout Description Set \begin_inset space ~ \end_inset languages \begin_inset space ~ \end_inset globally When this option is set, the languages used in the document will be added as options to the document class options, so that they can be used by all \SpecialChar LaTeX -packages. Otherwise they will only be used as options for the \series bold babel \series default package. \end_layout \begin_layout Description Auto \begin_inset space ~ \end_inset begin When this option is set, documents start with the chosen document language. When this option is not set, the \family sans Command \begin_inset space ~ \end_inset start \family default is explicitly set to the beginning of the document in the \SpecialChar LaTeX -output. This assures that the correct language is used when you use another \family sans Command \begin_inset space ~ \end_inset start \family default than the default. \end_layout \begin_layout Description Auto \begin_inset space ~ \end_inset end Counterpart to \family sans Auto \begin_inset space ~ \end_inset begin \family default . When it is not set, the \family sans Command \begin_inset space ~ \end_inset end \family default is set to the end of the document. \end_layout \begin_layout Description Mark \begin_inset space ~ \end_inset foreign \begin_inset space ~ \end_inset languages Text marked formatted in a language different from the document language will be underlined in blue. \end_layout \begin_layout Description Enable \begin_inset space ~ \end_inset RTL \begin_inset space ~ \end_inset support Enables the use of languages, written from right to left (RTL), like Arabic, Hebrew or Farsi. \end_layout \begin_layout Description Cursor \begin_inset space ~ \end_inset movement When writing RTL, you can define if the left and right arrow keys move the cursor visually to the left or right, respectively, or logically. Logical means that the cursor is moved to the left when pressing the right arrow key and the cursor is inside text in an RTL language. \end_layout \begin_layout Subsection Spellchecker \end_layout \begin_layout Standard The spellchecker settings are explained in section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Spellchecking" \end_inset . \end_layout \begin_layout Section Outputs \end_layout \begin_layout Subsection General \begin_inset CommandInset label LatexCommand label name "subsec:General-output" \end_inset \end_layout \begin_layout Description Forward \begin_inset space ~ \end_inset search Commands that will be used for the menu \family sans Navigate\SpecialChar menuseparator Forward \begin_inset space ~ \end_inset search \family default .

Combinations of the encodings are possible, like \begin_inset Quotes eld \end_inset \family sans T1, T2B \family default \begin_inset Quotes erd \end_inset . The font encoding is normally automatically loaded by the language packages \SpecialChar LyX sets up in the background. So there is no need to change the default encoding. \change_unchanged \end_layout \begin_layout Description DVI \begin_inset space ~ \end_inset viewer \begin_inset space ~ \end_inset paper \begin_inset space ~ \end_inset size \begin_inset space ~ \end_inset options They only have an effect when the program \family sans xdvi \family default is used as DVI-viewer, read its manual to find out more. \end_layout \begin_layout Standard Here you can also specify options and commands with parameters for processors.
