Now, do not panic – you will not need to learn \SpecialChar LaTeX to use \SpecialChar LyX . That is, after all, the whole point of \SpecialChar LyX : to provide an almost-WYSIWYG interface to \SpecialChar LaTeX . There are some things you will need to learn, however, in order to use \SpecialChar LyX effectively. \end_layout \begin_layout Standard Some of you probably found your way to this document because you tried to put two spaces after a \begin_inset Quotes eld \end_inset . \begin_inset Quotes erd \end_inset or tried to put three blank lines between paragraphs. You found out you could not and, in fact, you will find out that most of the little tricks you are accustomed to use in word processors will not work in \SpecialChar LyX . That is because most word processors you have used before allow you manually to enter all spacings, font changes, and so on. So you end up not only writing a document but typesetting it, too. \SpecialChar LyX does the typesetting for you, in a consistent fashion, letting you focus on the important things, like the content of your writing. \end_layout \begin_layout Standard So read on to learn more about \SpecialChar LyX . Reading this tutorial is definitely worth the time. \end_layout \begin_layout Section What the Tutorial \emph on is \emph default and what it \emph on is not \end_layout \begin_layout Standard Before we get started with this section, you need to know that this \emph on Tutorial \emph default uses the notation outlined in the \emph on Introduction \emph default manual. If you came to this manual first, please read the \emph on Introduction \emph default before you continue with the \emph on Tutorial \emph default . \end_layout \begin_layout Standard Now that you know which fonts mean what in the documentation, we want to talk a bit about what this \emph on Tutorial \emph default is for. \end_layout \begin_layout Subsection Getting the most out of the Tutorial \end_layout \begin_layout Standard This tutorial consists of examples and exercises. To get the most out of this document, you should read through it, typing all the little things we are telling you to type and trying out all of the exercises to see if you get them right. For convenience, you might want to print out the PDF version of this document. \end_layout \begin_layout Standard If you are familiar with \SpecialChar LaTeX , you will probably be able to read the \emph on Tutorial \emph default somewhat faster, since many \SpecialChar LyX ideas are just \SpecialChar LaTeX ideas in disguise. However, \SpecialChar LyX has features you will want to learn about. Even if you do not feel like reading the rest of the \emph on Tutorial \emph default , you should definitely check out Section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:latexusers" \end_inset , which is specifically written for experienced \SpecialChar LaTeX users. \end_layout \begin_layout Subsection What you \emph on will not \emph default find \end_layout \begin_layout Itemize Detailed explanations of all of \SpecialChar LyX 's features. \end_layout \begin_deeper \begin_layout Standard Look in the \emph on User's Guide \emph default when you need this. \end_layout \end_deeper \begin_layout Itemize Detailed explanations of \SpecialChar LaTeX . \end_layout \begin_deeper \begin_layout Standard Unnecessary. If you want to learn some of the neat tricks you can do with \SpecialChar LaTeX in \SpecialChar LyX , you can have a look at the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual. \end_layout \end_deeper \begin_layout Standard It is time to move on, time for your first document \SpecialChar ldots \end_layout \begin_layout Chapter Getting started with \SpecialChar LyX \end_layout \begin_layout Section Your first \SpecialChar LyX document \end_layout \begin_layout Standard OK\SpecialChar endofsentence You are ready to start writing. Before you do, there are a few things we need to mention, which will hopefully make the Tutorial more instructive and useful. \end_layout \begin_layout Standard Because there is information we cannot give you in the Tutorial, the \emph on first \emph default \series medium thing that you need to do is find the \series default other \series medium help files. This is very simple: \series default Start up \SpecialChar LyX , select the \emph on User's Guide \emph default from the \family sans Help \family default menu. You may want to load the \emph on Tutorial \emph default as well (if you are not reading it within \SpecialChar LyX already). This way, you can read them while you are writing your own file. \begin_inset Foot status collapsed \begin_layout Plain Layout They can also serve as good examples of how to use the many features of \SpecialChar LyX . \end_layout \end_inset Note that once you have got more than one document open, you can use the \family sans View \family default menu or the document tabs to switch between them. \end_layout \begin_layout Standard In this Tutorial, we are going to assume that you have a fully working version of \SpecialChar LyX , as well as a \SpecialChar LaTeX -distribution and a PDF-viewer. This should be the case on all major Linux- and BSD-distributions, as well as on Windows, where this is setup by the \SpecialChar LyX installers. \end_layout \begin_layout Standard Finally, we have written a file called \change_deleted -712698321 1553351112 \family typewriter example_raw.lyx \change_inserted -712698321 1553351120 \family default \emph on Example (raw) \change_unchanged \emph default to let you practice your \SpecialChar LyX skills. Imagine that it was typed by someone who did not know about any of \SpecialChar LyX 's great features. As you learn new \SpecialChar LyX functions, we will suggest that you fix those parts of \change_deleted -712698321 1553351165 \family typewriter example_raw.lyx \change_inserted -712698321 1553351165 \family default \emph on Example (raw) \change_unchanged \emph default . It also contains \begin_inset Quotes els \end_inset subtle \begin_inset Quotes ers \end_inset hints about how to fix things. \begin_inset Foot status collapsed \begin_layout Plain Layout The hints are located in yellow \begin_inset Quotes eld \end_inset Notes \begin_inset Quotes erd \end_inset . Access the text in a note by clicking on it. \end_layout \end_inset If you want to cheat, or check what you have done, there is also a file called \change_deleted -712698321 1553351273 \family typewriter example_lyxified.lyx \change_inserted -712698321 1553351278 \family default \emph on Example (LyXified) \change_unchanged \emph default which contains the same text written and typeset by a \SpecialChar LyX master. \end_layout \begin_layout Standard The example files can be found in \change_inserted -712698321 1553351405 the \begin_inset Quotes eld \end_inset General \begin_inset Quotes erd \end_inset section of \family sans File\SpecialChar menuseparator Open Example\SpecialChar ldots \change_deleted -712698321 1553351425 \family default the \family typewriter examples \family default directory of \SpecialChar LyX 's installation folder \change_unchanged . Open the document \change_deleted -712698321 1553351441 \family typewriter example_raw.lyx \change_inserted -712698321 1553351441 \family default \emph on Example (raw) \change_unchanged \emph default and use \family sans File\SpecialChar menuseparator Save \begin_inset space ~ \end_inset As \family default to save a copy in your own directory for you to work on. As you fix parts of the raw document, check to see how those changes affect the output. \end_layout \begin_layout Standard By the way, \change_deleted -712698321 1553351473 the \family typewriter examples \family default directory \change_inserted -712698321 1553351473 \family sans File\SpecialChar menuseparator Open Example\SpecialChar ldots \change_unchanged \family default contains lots of other examples files. They will show you how to do various fancy things with \SpecialChar LyX . After you have read the Tutorial, or when you are confused about how to do something fancy in \SpecialChar LyX , take a look at these files. \end_layout \begin_layout Subsection Typing, Viewing, and Exporting \end_layout \begin_layout Itemize Open a new file with \family sans File\SpecialChar menuseparator New \end_layout \begin_layout Itemize Type a sentence like: \family typewriter This is my first \SpecialChar LyX document! \end_layout \begin_layout Itemize Save your document with \family sans File\SpecialChar menuseparator Save \begin_inset space ~ \end_inset As\SpecialChar endofsentence \end_layout \begin_layout Itemize Create a PDF file, with \family sans Document\SpecialChar menuseparator View \family default or the toolbar button \begin_inset Info type "icon" arg "buffer-view" \end_inset . \SpecialChar LyX will open a PDF-viewer program displaying your document as it will look when printed. \end_layout \begin_layout Itemize Export the ready to print document with \family sans File\SpecialChar menuseparator Export \family default to a format you want \family sans . \end_layout \begin_layout Standard Congratulations! You have written your first \SpecialChar LyX document. All of the rest is just details. \begin_inset Newline newline \end_inset \end_layout \begin_layout Standard \series bold A hint: \series default You can save time by leaving the PDF viewer running in the background. Under MacOS and Linux you can use \family sans Document\SpecialChar menuseparator Update \family default or the toolbar button \begin_inset Info type "icon" arg "buffer-update" \end_inset and just click on the PDF viewer window afterwards. Under Windows still use \family sans Document\SpecialChar menuseparator View \family default or \begin_inset Info type "icon" arg "buffer-view" \end_inset respectively. \end_layout \begin_layout Standard \series bold Another hint: \series default In case you are using a high-resolution display, the LyX toolbar icons are quite small. To change their size, right-click into a toolbar. \end_layout \begin_layout Subsection Simple Operations \end_layout \begin_layout Standard \SpecialChar LyX can of course do most of the things you are used to doing with a word processor. It will word-wrap and indent paragraphs automatically. Here is a quick description of how to do some simple actions. \end_layout \begin_layout Description Undo \SpecialChar LyX has multiple levels of undo, which means you can undo everything you have done since your current editing session started, by selecting \family sans Edit\SpecialChar menuseparator Undo \family default (toolbar button \begin_inset Info type "icon" arg "undo" \end_inset ) over and over again. If you undo too much, just select \family sans Edit\SpecialChar menuseparator Redo \family default (toolbar button \begin_inset Info type "icon" arg "redo" \end_inset ) to get it back. \end_layout \begin_deeper \begin_layout Standard Currently, undo is limited to 100 steps. \end_layout \end_deeper \begin_layout Description Cut/Paste/Copy Use \family sans Edit\SpecialChar menuseparator Cut \family default (toolbar button \begin_inset Info type "icon" arg "cut" \end_inset ), \family sans Edit\SpecialChar menuseparator Copy \family default (toolbar button \begin_inset Info type "icon" arg "copy" \end_inset ), and \family sans Edit\SpecialChar menuseparator Paste \family default (toolbar button \begin_inset Info type "icon" arg "paste" \end_inset ) to cut, copy, and paste. Or automatically paste selected text (including selections from other programs) with the \emph on middle mouse button \emph default . \end_layout \begin_layout Description Find/Replace Use \family sans Edit\SpecialChar menuseparator Find \begin_inset space ~ \end_inset & \begin_inset space ~ \end_inset Replace \family default (toolbar button \begin_inset Info type "icon" arg "dialog-show findreplace" \end_inset ) to search. In the dialog, search with the \family sans Find \begin_inset space ~ \end_inset Next \family default button, and use the \family sans Replace \family default button to replace a word you have found. \begin_inset Foot status collapsed \begin_layout Plain Layout Close the window when you are done or leave it open if you find it more convenient. Most dialog boxes in \SpecialChar LyX can operate like this. Just be sure you have the right window in focus when you are trying to type in the main \SpecialChar LyX window or a \SpecialChar LyX dialog. \end_layout \end_inset If you like, you can specify whether to make the search case-sensitive, or to search for only complete words; you can also search backwards through the document. \end_layout \begin_layout Description Character \begin_inset space ~ \end_inset Formatting You can \emph on emphasize \emph default text (toolbar button \begin_inset Info type "icon" arg "font-emph" \end_inset , which will by default print characters in italics), set it in \noun on Noun Style \noun default (toolbar button \begin_inset Info type "icon" arg "font-noun" \end_inset , usually small caps, used for people's names), or use your own formatting by using the \family sans Edit\SpecialChar menuseparator Text \begin_inset space ~ \end_inset Style\SpecialChar menuseparator Customized \family default dialog (toolbar button \begin_inset Info type "icon" arg "dialog-show character" \end_inset ). \end_layout \begin_layout Description Toolbar Other buttons on the toolbar allow you to do some of the more popular functions, such as \family sans Insert \begin_inset space ~ \end_inset math \family default , \family sans Insert \begin_inset space ~ \end_inset graphics \family default and \family sans Insert \begin_inset space ~ \end_inset table \family default . \end_layout \begin_layout Standard Of course, you have not yet written enough to make most of these functions useful. As you write more, though, try undoing, pasting, etc. \end_layout \begin_layout Subsection WYSIWYM: Whitespace in \SpecialChar LyX \end_layout \begin_layout Standard One of the hardest things for new users to get used to is the way that \SpecialChar LyX handles whitespace. As many times as you hit \family sans Return \family default , you will only get one blank line. As many times as you hit \family sans Space \family default , you will only get one space. On a blank line, \SpecialChar LyX will not let you type even one space. The \family sans Tab \family default key will not move you forward one tab stop; in fact there \emph on are \emph default no tab stops! There is no ruler at the top of the page to let you set tabs or margins, either. \end_layout \begin_layout Standard Many word processors are based on the WYSIWYG principle: \begin_inset Quotes eld \end_inset What You See Is What You Get. \begin_inset Quotes erd \end_inset \SpecialChar LyX , on the other hand, is based on the principle that \begin_inset Quotes eld \end_inset What You See Is What You \emph on Mean \emph default . \begin_inset Quotes erd \end_inset You type what you mean and \SpecialChar LyX will take care of typesetting it for you so that the output looks nice. A \family sans Return \family default grammatically separates paragraphs and a \family sans Space \family default grammatically separates words; so there is no reason to have several of them in a row; a \family sans Tab \family default has no grammatical function at all – so \SpecialChar LyX does not support it. Using \SpecialChar LyX , you will spend more of your time worrying about the \emph on content \emph default of your document and less time worrying about the \emph on format. \emph default See the \emph on Introduction \emph default for more information on the WYSIWYM concept. \end_layout \begin_layout Standard \SpecialChar LyX does have (many) ways to fine-tune the formatting of your document. After all, \SpecialChar LyX might not typeset \emph on exactly \emph default what you mean. The \emph on User's Guide \emph default has information about all that. It includes horizontal fills and vertical space — which are more powerful and versatile than multiple spaces or blank lines — and ways to change font sizes, character styles, and paragraph alignments by hand. The idea, though, is that you can write your whole document, focusing on content, and just worry about that fine-tuning at the end. With standard word processors, you will be distracted by document formatting throughout the writing process. \end_layout \begin_layout Section Environments \end_layout \begin_layout Standard Different parts of a document have different purposes; we call these parts \emph on environments \emph default . Most of a document is made up of regular text. Section titles (chapter, subsection, etc.) let the reader know that a new topic or subtopic will be discussed. Certain types of documents have special environments. A journal article will have an abstract and a title. A letter will have neither of these, but will probably have an environment that gives the writer's address. \end_layout \begin_layout Standard Environments are a major part of the \begin_inset Quotes eld \end_inset What You See Is What You Mean \begin_inset Quotes erd \end_inset philosophy of \SpecialChar LyX . A given environment may require a certain font style, font size, indenting, line spacing, and more. This problem is aggravated, because the exact formatting for a given environmen t may change: one journal may use boldface, 18 point, centered type for section titles while another uses italicized, 15 point, left justified type; different languages may have different standards for indenting; and bibliography formats can vary widely. \SpecialChar LyX lets you avoid learning all the different formatting styles. \end_layout \begin_layout Standard The \family sans Environment \family default choice box is located on the left end of the toolbar and looks like this: \begin_inset Graphics filename clipart/ToolbarEnvBox.png scale 75 clip \end_inset . It indicates in which environment you are currently writing. While you were writing your first document, it said \begin_inset Quotes eld \end_inset Standard, \begin_inset Quotes erd \end_inset which is the default environment for text. Now you will put a number of environments in your new document so that you can see how they work. \end_layout \begin_layout Subsection Sections and Subsections \end_layout \begin_layout Standard Type the word \family typewriter Introduction \family default on the first line of your new \SpecialChar LyX file, and select \family sans Section \family default in the \family sans Environment \family default box. \begin_inset Foot status collapsed \begin_layout Plain Layout You do not have to \emph on select \emph default the line. If nothing is selected, \SpecialChar LyX changes the paragraph you are currently in to the selected environment. Alternatively, you can change several paragraphs to a different environment by selecting them before picking an environment. \end_layout \end_inset Be sure to use \family sans Section \family default and \emph on not \emph default \family sans Section* \family default , which will be covered below. \SpecialChar LyX numbers the section \begin_inset Quotes eld \end_inset 1 \begin_inset Quotes erd \end_inset and typesets the section heading (title) in a larger font. Now hit \family sans Return \family default \SpecialChar endofsentence Note that the \family sans Environment \family default box changes from \begin_inset Quotes eld \end_inset Section \begin_inset Quotes erd \end_inset back to \begin_inset Quotes eld \end_inset Standard \begin_inset Quotes erd \end_inset . Section headings, like most environments, are assumed to end when you type \family sans Return \family default \SpecialChar endofsentence Type the document introduction: \end_layout \begin_layout LyX-Code This is an introduction to my first \SpecialChar LyX document. \end_layout \begin_layout Standard Hit \family sans Return \family default again, and select \family sans Section \family default from the \family sans Environment \family default box again. \SpecialChar LyX writes a \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset and waits for you to type a title. Type \begin_inset Quotes eld \end_inset \family typewriter More \begin_inset space ~ \end_inset Stuff \family default \begin_inset Quotes erd \end_inset , and you will see that \SpecialChar LyX again sets it as a section title. \end_layout \begin_layout Standard It gets better. Go to the end of Section \begin_inset space ~ \end_inset 1 again (after \begin_inset Quotes eld \end_inset my first \SpecialChar LyX document. \begin_inset Quotes erd \end_inset ) and hit \family sans Return \family default again, and select \family sans Section \family default from the \family sans Environment \family default box again. Again, \SpecialChar LyX writes \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset and waits for you to type a title. Type \family typewriter About This Document \family default . Section \begin_inset space ~ \end_inset \begin_inset Quotes eld \end_inset More Stuff \begin_inset Quotes erd \end_inset , which was Section \begin_inset space ~ \end_inset 2, has been automatically renumbered to Section \begin_inset space ~ \end_inset 3! In true WYSIWYM fashion, you just need to identify the text that makes up the section titles, and \SpecialChar LyX takes care of numbering the sections and typesettin g them. \end_layout \begin_layout Standard Hit \family sans Return \family default to get back to the \family sans Standard \family default environment, and type the following five lines: \end_layout \begin_layout LyX-Code Sections and subsections are described below. \end_layout \begin_layout LyX-Code Section Description \end_layout \begin_layout LyX-Code Sections are bigger than subsections. \end_layout \begin_layout LyX-Code Subsection description \end_layout \begin_layout LyX-Code Subsections are smaller than sections. \end_layout \begin_layout Standard Click on the second line and select \family sans Subsection \family default from the \family sans Environment \family default box. \SpecialChar LyX numbers the subsection \begin_inset Quotes eld \end_inset 2.1 \begin_inset Quotes erd \end_inset , and typesets it in a font which is bigger than regular text but smaller than the section title. Change the fourth line to the \family sans Subsection \family default environment as well. As you probably expected, \SpecialChar LyX automatically numbered the section \begin_inset Quotes eld \end_inset 2.2 \begin_inset Quotes erd \end_inset . If you put yet another section before Section \begin_inset space ~ \end_inset 2, Section \begin_inset space ~ \end_inset 2 will be renumbered as Section 3, and the subsections will be renumbered to \begin_inset Quotes eld \end_inset 3.1 \begin_inset Quotes erd \end_inset and \begin_inset Quotes eld \end_inset 3.2 \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Standard Further levels of sectioning include \family sans Subsubsection \family default , \family sans Paragraph \family default , and \family sans Subparagraph \family default . We will let you play with these on your own. You may notice that paragraph and subparagraph headings are not numbered by default, and that subparagraphs are indented; see the \emph on User's Guide \emph default for an explanation and how to change this. \family sans Chapter \family default headings are actually the highest level of sectioning, above \family sans Section \family default s, but you are only allowed to use them in certain types (text classes) of \SpecialChar LyX documents (see Section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Document-Classes" \end_inset ). \end_layout \begin_layout Standard Finally, you may want to have sections or subsections that are not numbered. There are environments for this as well. If you change one of your section headings to the \family sans Section* \family default environment (you may have to scroll down in the \family sans Environment \family default box to find it), \SpecialChar LyX will use the same font size for the heading as it uses for a regular section, but it will not number that section. There are corresponding \begin_inset Quotes eld \end_inset starred \begin_inset Quotes erd \end_inset heading environments for \family sans Subsection \family default and \family sans Subsubsection \family default . Try changing some of your sections or subsections to the starred environments, and note how the other section numbers are updated. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Fix the section and subsection headings in \change_inserted -712698321 1553351516 \emph on Example (raw) \change_deleted -712698321 1553351522 \emph default \begin_inset Newline newline \end_inset \family typewriter example_raw.lyx \family default . \change_unchanged \end_layout \begin_layout Subsection Lists and sublists \end_layout \begin_layout Standard \SpecialChar LyX has several different environments for typesetting lists. The various list environments free you from hitting \family sans Tab \family default a million times when writing an outline, or from renumbering a whole list when you want to add a point in the middle of the list. Different types of documents logically require different list environments: \end_layout \begin_layout Itemize A slide presentation might use the \family sans Itemize \family default environment's bulleted lists to describe different points. \end_layout \begin_layout Itemize An outline would use the \family sans Enumerate \family default environment's numbered lists (and lettered sublists). \end_layout \begin_layout Itemize A document describing several software packages could use the \family sans Description \family default environment, where each item in the list begins with a bold-faced word. \end_layout \begin_layout Itemize The \family sans List \family default (also named \family sans Labeling \family default ) environment is a variation on the \family sans Description \family default environment. \end_layout \begin_layout Standard Let us write a list of reasons why \SpecialChar LyX is better than other word processors. Somewhere in your document, type: \end_layout \begin_layout Standard \family typewriter \SpecialChar LyX is better than other word processors because: \end_layout \begin_layout Standard and hit \family sans Return \family default . Now select \family sans Itemize \family default from the \family sans Environment \family default box ( \begin_inset Info type "icon" arg "layout-toggle Itemize" \end_inset ). \SpecialChar LyX writes a \begin_inset Quotes eld \end_inset bullet \begin_inset Quotes erd \end_inset on the line. Type in your reasons: \end_layout \begin_layout LyX-Code Typesetting is done for you. \end_layout \begin_layout LyX-Code Math is WYSIWYG \end_layout \begin_layout LyX-Code Lists are very easy to create! \end_layout \begin_layout Standard List environments, unlike headings, do not end when you type \family sans Return \family default . Instead, \SpecialChar LyX assumes you are going on to the next item in the list. The above will therefore result in a three-item list. If you want more than one paragraph within one list \emph on item \emph default , one way is to use the \family sans Protected \begin_inset space ~ \end_inset Break \family default , which you get by typing \family sans Ctrl+Return \family default . In order to get out of the list, you need to reselect the \family sans Standard \family default environment (or just use the key binding \begin_inset Info type "shortcut" arg "layout Standard" \end_inset ). \end_layout \begin_layout Standard You now have a beautiful itemized list. You might want to run \SpecialChar LaTeX to see how the list looks when printed out. But what if you wanted to number the reasons? Well, just select the whole list \begin_inset Foot status collapsed \begin_layout Plain Layout \SpecialChar LyX will not let you select the first bullet (or the actual number in a numbered section title) unless you also select the paragraph \emph on before \emph default it, which you probably do not want to do. This is on purpose because the bullet or number depends on the document settings or text position, respectively. \end_layout \end_inset and choose \family sans Enumerate \family default from the \family sans Environment \family default box ( \begin_inset Info type "icon" arg "layout-toggle Enumerate" \end_inset ). Pow! As we mentioned, if you add or delete a list item, \SpecialChar LyX will fix the numbering. \end_layout \begin_layout Standard While the list is still selected, you can change to the other two list environme nts, \family sans Description \family default and \family sans List \begin_inset space \thinspace{} \end_inset \family default / \begin_inset space \thinspace{} \end_inset \family sans Labeling \family default ( \begin_inset Info type "icon" arg "layout-toggle Description" \end_inset and \begin_inset Info type "icon" arg "layout-toggle List" \end_inset ), in order to see what they look like. For those two environments, each list item is made up of a term, which is the item's first word, followed by a definition, which is the rest of the paragraph (until you hit \family sans Return \family default ). The term is either typeset in boldface ( \family sans Description \family default ) or separated by a \begin_inset Quotes eld \end_inset Tab \begin_inset Quotes erd \end_inset \begin_inset Foot status collapsed \begin_layout Plain Layout But a typesetter's tab, which will change to fit the size of the largest term, not a pathetic, rigid, unchangeable typewriter \family sans Tab \family default . \end_layout \end_inset ( \family sans List \family default ) from the rest of the paragraph.

Computer code (the \family sans \SpecialChar LyX -Code \family default environment \begin_inset Foot status collapsed \begin_layout Plain Layout used in this Tutorial for the long typing examples \end_layout \end_inset ) is written in a \family typewriter typewriter \family default font; this environment is the only place in \SpecialChar LyX where you are allowed to use multiple spaces to allow code indenting. You can even write poetry using the \family sans Verse \family default style, using \family sans Return \family default to separate stanzas, and \family sans Ctrl+Return \family default to separate lines within a stanza.

It introduced you to the basic editing operations in \SpecialChar LyX , as well as the powerful method of writing with environments. Most people who use \SpecialChar LyX , though, will want to write documents: papers, articles, books, manuals, or letters. This chapter is meant to take you from simply writing text with \SpecialChar LyX to writing a complete document. It will introduce you to text classes, which allow you to write different sorts of documents. It will then describe many of the additions that turn text into a document, such as titles, footnotes, cross references, bibliographies, and tables of contents. \end_layout \begin_layout Section Document Classes \begin_inset CommandInset label LatexCommand label name "sec:Document-Classes" \end_inset \end_layout \begin_layout Standard Different sorts of documents should be typeset differently. For example, books are generally printed double-sided, while articles are single-sided. In addition, many documents contain special environments: letters contain some environments — such as the sender's address and the signature — which do not make sense in a book or article. The \SpecialChar LyX \emph on document class \emph default \begin_inset Foot status collapsed \begin_layout Plain Layout for \SpecialChar LaTeX users: this is equivalent to the \SpecialChar LaTeX document class \end_layout \end_inset takes care of these large scale differences between different sorts of documents. This Tutorial, for example, was written in the \family sans Book \family default document class. Document classes are another major part of the WYSIWYM philosophy; they tell \SpecialChar LyX how to typeset the document, so you do not need to know how. \end_layout \begin_layout Standard Your document is probably being written in the \family sans Article \family default document class. \begin_inset Foot status collapsed \begin_layout Plain Layout That is usually the default document class \end_layout \end_inset Try changing to other document classes (using the \family sans Document\SpecialChar menuseparator Settings \family default dialog) to see how they are typeset differently. If you change your document to the \family sans Book \family default document class and look at the \family sans Environment \family default box, you will see that most of the allowed environments are the same. However, you can now use the \family sans Chapter \family default environment. If you are ever unsure about which environments you can use in a given document class, just consult the \family sans Environment \family default box. \end_layout \begin_layout Standard Font sizes, one- or two-column printing, and page headings are just some of the ways journals' typesettings differ from one another. As the Computer Age continues to mature, journals have begun accepting electronic submissions, creating \SpecialChar LaTeX \begin_inset Quotes eld \end_inset style files \begin_inset Quotes erd \end_inset so that authors can submit correctly typeset articles. \SpecialChar LyX is set up to support this as well. For example, \SpecialChar LyX supports typesetting (and extra environments) for the American Mathematics Society journals using the \family sans Article \begin_inset space ~ \end_inset (AMS) \family default document class. \end_layout \begin_layout Standard Here is a very quick reference to some of the document classes.

While this is the most obvious way to write a letter, it seems like extra work. Every time you write a business letter, you want to have your address, the address to which you are sending it, a body, a signature, etc. \SpecialChar LyX therefore has a \emph on template \emph default for letters, which contains a sample letter; once you have a template, you can just replace a couple of parts of the letter with your text each time you write a letter. \end_layout \begin_layout Standard Open a new file with \family sans File\SpecialChar menuseparator New \begin_inset space ~ \end_inset from \begin_inset space ~ \end_inset Template \change_inserted -712698321 1553351676 \family default \SpecialChar ldots \change_unchanged .

Save and print the file to see how the various environments are typeset. \end_layout \begin_layout Standard When you look at the \family sans Environment \family default box, you will see several environments, like the \family sans My \begin_inset space ~ \end_inset Address \family default environment, that do not exist in most other document classes. Others, like \family sans Description \family default , are familiar. You can play around for a while to figure out how the various environments work. You will notice for example that the \family sans Signature \family default environment has the word \begin_inset Quotes eld \end_inset Signature: \begin_inset Quotes erd \end_inset in red before the actual text of the signature. This word does not show up in the actual letter, as you will see if you view/export the file. It is just there to let you know where the signature goes. Also, note that it does not matter where in the file the \family sans Signature \family default line is placed. Remember, \SpecialChar LyX is WYSIWYM; you can put the \family sans Signature \family default environment anywhere you want, but \SpecialChar LyX knows that in the printout, the signature should be at the end. \end_layout \begin_layout Standard A template is just a regular \SpecialChar LyX file. This means you can fill in your address and signature and save the file as a new template. From now on, any time you want to write a letter, you can use the new template to save time. We do not have to suggest an actual \begin_inset Quotes eld \end_inset exercise \begin_inset Quotes erd \end_inset here; just write a letter to someone! \begin_inset Foot status collapsed \begin_layout Plain Layout One warning, if you are writing from a template. If you erase all of the text in an environment — for example, if you erase the whole \family sans My \begin_inset space ~ \end_inset Address \family default field so that you can replace it with your own — and then you move the cursor without writing any text, the environment may disappear. This is because most environments cannot exist without any text in them. Just reselect the environment from the \family sans Environment \family default box to get it back. \end_layout \end_inset \end_layout \begin_layout Standard Templates can be a huge time-saver, and we urge you to use them whenever possible. In addition, they can help a person learn how to use some of the fancier document classes. Finally, they may be useful for a person who is configuring \SpecialChar LyX for a bunch of less computer-aware users. When they are first learning \SpecialChar LyX , it will be less intimidating if they have a letter template customized for their company, for example. \end_layout \begin_layout Standard \begin_inset Newpage newpage \end_inset \end_layout \begin_layout Section Document Titles \end_layout \begin_layout Standard \SpecialChar LyX (like \SpecialChar LaTeX ) considers the title — which may contain the actual title, the author, the date, and even an abstract of a paper — to be a separate part of the document. \end_layout \begin_layout Standard Go back to your first \SpecialChar LyX document and make sure it is using the \family sans Article \family default document class. \begin_inset Foot status collapsed \begin_layout Plain Layout You should not be using the letter any more, since the \family sans Letter \family default document class does not allow titles. \end_layout \end_inset Type a title on the first line, and change the line to the \family sans Title \family default environment. On the next line, type your name and change it to the \family sans Author \family default environment. On the next line, write the date in the \family sans Date \family default environment. Type a paragraph or two summarizing your document using the \family sans Abstract \family default environment. Notice how the title is presented when it is printed out. If you change the document format to Book, you will get a separate title page, like the first page of this tutorial. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Fix the title, date, and author in \change_deleted -712698321 1553351568 \family typewriter example_raw.lyx \change_inserted -712698321 1553351568 \family default \emph on Example (raw) \change_unchanged \end_layout \begin_layout Section Labels and Cross-References \end_layout \begin_layout Standard You can label section headings, list items, formulas, footnotes, and floats \begin_inset Foot status collapsed \begin_layout Plain Layout Floats are explained in the \emph on User's Guide \emph default and the \emph on Embedded Objects \emph default manual. \end_layout \end_inset in your document. Once you do so, you can refer to the element in other parts of the document, using cross-references. You can refer to a section's number, to the page on which the section begins or to both. As with section numbering, \SpecialChar LyX also takes care of cross-reference numbering for you. Automatic management of labels and cross-references is among the most significa nt advantages of \SpecialChar LyX (and \SpecialChar LaTeX ) over conventional word processors. \end_layout \begin_layout Subsection Your first label \end_layout \begin_layout Standard Go to our second section, whose title is \begin_inset Quotes eld \end_inset About This Document \begin_inset Quotes erd \end_inset . Click at the end of the section title line, and select \family sans Insert\SpecialChar menuseparator Label \family default or the toolbar button \begin_inset Info type "icon" arg "label-insert" \end_inset . A dialog asks you for a label name, and gives you a suggestion. When you click on \family sans OK \family default , the label name will be placed in a box next to the section title. \end_layout \begin_layout Standard So far you have not done anything — the output will look exactly the same, since labels do not show up in the printed document. However, now that you have added a label, you can refer to that label with cross-references. We will do that next. \end_layout \begin_layout Subsection Your first cross-reference \end_layout \begin_layout Standard Place the cursor somewhere in Section \begin_inset space ~ \end_inset 2 of your document. Type \end_layout \begin_layout LyX-Code If you want to know more about this document, \begin_inset Newline newline \end_inset then see Section . \end_layout \begin_layout Standard Now, with the cursor before the final period, select \family sans Insert\SpecialChar menuseparator Cross \begin_inset space ~ \end_inset Reference \family default or the toolbar button \begin_inset Info type "icon" arg "dialog-show-new-inset ref" \end_inset . The Cross-reference dialog pops up. It shows a list of the possible labels you can reference. At the moment, there should be only one, \begin_inset Quotes eld \end_inset sec:About-This-Document \begin_inset Quotes erd \end_inset . First, select the drop-down menu labeled \begin_inset Quotes eld \end_inset Format \begin_inset Quotes erd \end_inset and select \begin_inset Quotes eld \end_inset \begin_inset Quotes erd \end_inset . Then select \begin_inset Quotes eld \end_inset sec:About-This-Document \begin_inset Quotes erd \end_inset (it may be selected by default), and a reference marker will appear containing \begin_inset Quotes eld \end_inset Ref: sec:About-This-Document \begin_inset Quotes erd \end_inset (To be really correct, you should put a \family sans Protected \begin_inset space ~ \end_inset Space \family default (shortcut \begin_inset Info type "shortcut" arg "command-alternatives math-space ; space-insert protected" \end_inset ) in between the word \begin_inset Quotes eld \end_inset Section \begin_inset Quotes erd \end_inset and the reference.) An alternative way to reference a label is to right-click the label and select \family sans Copy as Reference \family default in the pop-up context menu. The cross-reference to this label is now in the clipboard and can be copied 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 ). In the printed document, this reference marker will be replaced with the section number. Preview your document and you will see that \SpecialChar LaTeX has been even cleverer than that. It refers to \begin_inset Quotes eld \end_inset Section 2 \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Standard Conveniently, a cross-reference acts as a hyperlink when you are editing a document in \SpecialChar LyX ; clicking on it will pop up the \family sans Cross-reference \family default dialog, clicking \family sans Go \begin_inset space ~ \end_inset to \begin_inset space ~ \end_inset Label \family default will move the cursor to the referenced label. \end_layout \begin_layout Subsection More fun with labels \end_layout \begin_layout Standard We told you that \SpecialChar LyX takes care of numbering cross-references; now you can test this claim. Add a new section before Section \begin_inset space ~ \end_inset 2. Update the preview, and — voilà! — the section cross-reference changed to \begin_inset Quotes eld \end_inset 3 \begin_inset Quotes erd \end_inset ! Change the section \begin_inset Quotes eld \end_inset About this Document \begin_inset Quotes erd \end_inset to a subsection, and the cross-reference will reference Subsection \begin_inset space ~ \end_inset 2.1 instead of Section \begin_inset space ~ \end_inset 3. The page reference will not change unless you add a whole page of text before the label, of course. \end_layout \begin_layout Standard If you want some more practice with labels, then try putting a new label where your first cross-reference was, and refer to that label from elsewhere in the document. If you will be inserting cross-references often, it may be convenient to leave the \family sans Cross-reference \family default dialog open. \end_layout \begin_layout Standard If you want to confirm that the cross-referencing gets the pages right even for larger documents, \family sans Copy \family default a couple pages of text from the \emph on User's Guide \emph default to the clipboard, and \family sans Paste \family default them into your document. \begin_inset Foot status collapsed \begin_layout Plain Layout By the way, copying a chapter title may cause an error, because chapters are not allowed in the article class, see Section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:Document-Classes" \end_inset .

The bibliography contains a list of references at the end of the document, and they can be referenced from within the document. Like section titles, \SpecialChar LyX and \SpecialChar LaTeX make your job easier by automatically numbering the bibliography items and changing citations when the item numbers change. \end_layout \begin_layout Standard Go to the end of the document and switch to the \family sans Bibliography \family default environment. Now, each paragraph you type will be a reference. Type \begin_inset Quotes eld \end_inset \family typewriter The Lyx Tutorial, by the \SpecialChar LyX Documentation Team \family default \begin_inset Quotes erd \end_inset as your first reference. Note that \SpecialChar LyX automatically puts a number in a box before each reference. Click on the boxed reference number, and the \family sans Bibliography \begin_inset space ~ \end_inset item \family default dialog box appears. The \family sans Key \family default is to refer to this reference within the \SpecialChar LyX document, the \family sans Label \family default appears in output. When no \family sans Label \family default is set (default), you will see the number of the bibliography in the output. Now change the \family sans Key \family default field to \begin_inset Quotes eld \end_inset lyxtutorial \begin_inset Quotes erd \end_inset to make it easy to remember. \end_layout \begin_layout Standard Now pick somewhere in your document that you would like to insert a reference. Do so with \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 \family sans Citation \family default dialog appears. The left panel in this dialog lists all the bibliography entries, and this field allows you to choose which bibliography item you want to cite. Select \begin_inset Quotes eld \end_inset lyxtutorial \begin_inset Quotes erd \end_inset (right now, that is the only item in the bibliography), then use the \family sans Add \family default button in the center to insert it. (You can have multiple citations in the same place by transferring a number of keys this way.) \begin_inset Foot status collapsed \begin_layout Plain Layout If one uses label names for references that are easy to remember it is easier to find the entry in the list of references. \end_layout \end_inset Click the \family sans OK \family default button.

If you want the references to have labels instead of numbers in the printed output (for example, some journals would use \begin_inset Quotes eld \end_inset [Smi95] \begin_inset Quotes erd \end_inset to refer to a paper written by Smith in 1995), use the \family sans Label \family default field in the \family sans Bibliography \begin_inset space ~ \end_inset item \family default dialog.

However, if you look at your preview, you will see that a table of contents has been generated, listing the various sections and subsections in your document. As usual, if you reorder sections or create new ones, you will see those changes in the preview when you update it. \end_layout \begin_layout Standard The table of contents is not printed in the on-screen version of the document. But you can display the table of contents in a separate window by clicking on the table of contents button, or by using \family sans View\SpecialChar menuseparator Outline \begin_inset space ~ \end_inset Pane \family default or the toolbar button \begin_inset Info type "icon" arg "dialog-toggle toc" \end_inset . This menu will work even if you do not have a table of contents inset in your document. This is a very useful tool for rearranging your document parts. Clicking on a (sub)section title in the \family sans Outline \family default window will highlight that line and move the display (in the \SpecialChar LyX editing window) to that place in the document. You can also use the arrow keys to move up and down in the table of contents. You may therefore find it convenient to leave this window open throughout editing sessions. You can get similar functionality from the \family sans Navigate \family default menu, though, where the table of contents appears automatically. \end_layout \begin_layout Standard To get rid of the Table of Contents, you can delete the table of contents button just like any other text. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Fix the table of contents in \change_deleted -712698321 1553351589 \family typewriter example_raw.lyx \change_inserted -712698321 1553351589 \family default \emph on Example (raw) \change_unchanged \end_layout \begin_layout Chapter Using Math \end_layout \begin_layout Standard \SpecialChar LaTeX is used by many scientists because it outputs great looking equations, avoiding the control characters used by word processors and their equation editors. Many of these scientists are frustrated, however, because writing equations in \SpecialChar LaTeX is more like programming than writing. Happily, \SpecialChar LyX has WYSIWYM support for equations. If you are used to \SpecialChar LaTeX , you will find that all of the usual \SpecialChar LaTeX math commands can be typed in normally, but they will show up in a WYSIWYM fashion. If, on the other hand, you have never written in \SpecialChar LaTeX , then the \family sans Math \family default toolbar will allow you to write professional-looking math quickly and easily. \end_layout \begin_layout Section Math Mode \end_layout \begin_layout Standard Somewhere in your \SpecialChar LyX document, type: \end_layout \begin_layout LyX-Code I like what Einstein said, E=mc^2, because it is \begin_inset Newline linebreak \end_inset so simple. \end_layout \begin_layout Standard Now, that equation does not look very good in \SpecialChar LyX and in the output; there is no space between the letters and the equals sign, and you would like to write an actual superscript for the \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset . That bad typesetting happened because we did not tell \SpecialChar LyX that we were writing a mathematical expression, so it typeset the equation like regular old text. \end_layout \begin_layout Standard But we can create a formula that will be typeset properly. Highlight the equation and click the toolbar button \begin_inset Info type "icon" arg "math-mode" \end_inset or use the menu \family sans Insert\SpecialChar menuseparator Math\SpecialChar menuseparator Inline \begin_inset space ~ \end_inset Formula \family default . If nothing is highlighted \SpecialChar LyX inserts a little blue square, which is an empty math formula. The expression appears in blue and the blue square disappears as soon as the formula is not empty. Now type \family sans Esc \family default to leave the equation. The purple markers disappear, leaving the cursor to the right of the expression. Now, if you type something, it will be regular text. \end_layout \begin_layout Standard Looking at the output you will notice that the expression was typeset nicely, with spaces between the letters and the equals sign, and a superscript \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset . Letters in math mode are assumed to be variables, and come out in italics. Numbers are just numbers. \end_layout \begin_layout Standard This math editor is another example of the WYSIWYM philosophy. In \SpecialChar LaTeX , you write a mathematical expression using text and commands like \family typewriter \backslash sqrt \family default ; this can be frustrating, because you cannot see what an expression looks like until you run the file under \SpecialChar LaTeX and you may have to spend time, for example, finding missing brackets. \SpecialChar LyX does not attempt to get the expression to look perfect (WYSIWYG), but it gives you an extremely good idea of what the expression will look like. \SpecialChar LaTeX then takes care of the professional typesetting. \end_layout \begin_layout Section Navigating an Equation \end_layout \begin_layout Standard Now let us change \begin_inset Formula $E=mc^{2}$ \end_inset to \begin_inset Formula $E=1+mc^{2}$ \end_inset . Use the arrow keys to move the cursor into the expression. Note that when you enter the expression, the purple markers appear to let you know you are editing math. Now you can use \family sans Left \family default and \family sans Right \family default to move the cursor past the equals sign, and just type \begin_inset Quotes eld \end_inset 1+ \begin_inset Quotes erd \end_inset . Again, you can use the arrow keys or \family sans Esc \family default to leave the formula\SpecialChar endofsentence \end_layout \begin_layout Standard Other than the special keys described below, typing in math mode is like editing regular text. Use \family sans Delete \family default (or \family sans Backspace \family default ) to delete things. Select text either with the arrow keys or with the mouse. \family sans Edit\SpecialChar menuseparator Undo \family default works in math mode as well as cut and paste. One thing to be careful of: if you are left or right outside a formula and you press \family sans Delete \family default or \family sans Backspace \family default respectively, you delete the whole formula. Luckily, you can just use \family sans Undo \family default to get it back. \end_layout \begin_layout Standard What if you want to change \begin_inset Formula $E=mc^{2}$ \end_inset to \begin_inset Formula $E=mc^{2.5}+1$ \end_inset ? Again, you can use the mouse to click in the right place. However, you can also use the arrow keys. If the cursor is just after the \begin_inset Quotes eld \end_inset c \begin_inset Quotes erd \end_inset but before the \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset , then press \family sans Up \family default and the cursor is moved to the level of the superscript, just before the \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset . Add the \begin_inset Quotes eld \end_inset .5 \begin_inset Quotes erd \end_inset . Now, hitting \family sans Down \family default will move the cursor back to the regular level. If you hit \family sans Space \family default instead of \family sans Down \family default , the cursor will be placed \emph on after \emph default the superscript (so that you can then type the \begin_inset Quotes eld \end_inset +1 \begin_inset Quotes erd \end_inset ). \end_layout \begin_layout Section Exponents and Indices \end_layout \begin_layout Standard An exponent can be entered from the \family sans Math \family default toolbar (see below), but it is actually simpler just to type the caret key, \begin_inset Quotes eld \end_inset ^ \begin_inset Quotes erd \end_inset . \SpecialChar LyX will place another blue rectangle in the superscript, so that whatever you write next will be superscripted, and in a smaller font size. Everything you type until you hit a \family sans Space \family default (or \family sans Esc \family default to exit the formula entirely) will be in the superscript. \end_layout \begin_layout Standard Writing a subscript (index) is just as easy; start one by typing the underscore key \begin_inset Quotes eld \end_inset _ \begin_inset Quotes erd \end_inset . You can subscript and superscript both subscripts and superscripts like this: \begin_inset Formula $A_{a_{0}+b^{2}}+C^{a_{0}+b^{2}}$ \end_inset . \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Put equation \begin_inset space ~ \end_inset 1 of \change_deleted -712698321 1553351597 \family typewriter example_raw.lyx \change_inserted -712698321 1553351597 \family default \emph on Example (raw) \change_unchanged \emph default into math mode. \end_layout \begin_layout Section The Math toolbar \end_layout \begin_layout Standard The \family sans Math \family default toolbar is a convenient way to enter symbols and/or to perform complicated formula operations. Many of these operations can be accomplished from the keyboard or the \family sans Insert\SpecialChar menuseparator Math \family default or the \family sans Edit\SpecialChar menuseparator Math \family default menus (the latter only appears when you are in Math mode). However, we are going to concentrate on using the \family sans Math \family default toolbar, just to let you know what is out there; you can learn keyboard shortcuts and commands later from the \emph on Math \emph default manual. \end_layout \begin_layout Standard The \family sans Math \family default toolbar is shown when the cursor is in a formula and can also be turned on manually in the menu \family sans View\SpecialChar menuseparator Toolbars \family default . When you click there on \begin_inset Quotes eld \end_inset Math \begin_inset Quotes erd \end_inset ( \begin_inset Info type "icon" arg "toolbar-toggle math" \end_inset ) the toolbar will be shown permanently at the bottom; this state is visualized in the \family sans Toolbars \family default menu with a checkmark. When you click in this state again on \begin_inset Quotes eld \end_inset Math \begin_inset Quotes erd \end_inset in the \family sans Toolbars \family default menu, the \family sans Math \family default toolbar is only shown when the cursor is within a formula; this state is visualized by the renaming of the menu entry from \begin_inset Quotes eld \end_inset Math \begin_inset Quotes erd \end_inset to \begin_inset Quotes eld \end_inset Math \begin_inset space ~ \end_inset (auto) \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Subsection Greek and symbols \end_layout \begin_layout Standard The \family sans Math \family default toolbar allows you to choose from a large array of symbols used in math: operators, arrows, relationships, delimiters, special characters, sums and integrals. Note that subscripting and superscripting allow you to put lower and upper limits on sums and integrals. \end_layout \begin_layout Subsection Roots, decorations, and delimiters \end_layout \begin_layout Standard To type a square root, just click on the button \begin_inset Info type "icon" arg "math-insert \\sqrt" \end_inset . The square root appears, and the cursor is in a new insertion point inside the square root. You can type variables, numbers, other square roots, fractions, whatever you want. \SpecialChar LyX will automatically resize the square root to fit what is inside. \end_layout \begin_layout Standard Adding a \begin_inset Quotes eld \end_inset frame decoration \begin_inset Quotes erd \end_inset to a character ( \begin_inset Formula $\overrightarrow{a}$ \end_inset ) or group of characters ( \begin_inset Formula $\overrightarrow{a+b}$ \end_inset ) is done similarly. Decorations are available from the toolbar via the button \begin_inset Info type "icon" arg "math-insert \\hat" \end_inset . Click on a decoration, and \SpecialChar LyX will insert that decoration with an insertion point under (or over) it. Just type what you want in the insertion point. There are two sets of decorations: those that resize with the text you type, and those that have a fixed size, and are most appropriate for a single letter. \end_layout \begin_layout Standard Delimiters such as parentheses, brackets, and braces work similarly, but are a bit more complicated. Hit the delimiter button \begin_inset Info type "icon" arg "dialog-show mathdelimiter" \end_inset to pop up the \family sans Math \begin_inset space ~ \end_inset Delimiter \family default dialog. Your current selection of delimiters is displayed in a box. It is a pair of parentheses by default, but you can choose a pair of braces, a brace and a parenthesis, or choose the empty square to have something like \begin_inset Quotes eld \end_inset \begin_inset Formula $a=\left\langle 7\right.$ \end_inset \begin_inset Quotes erd \end_inset (the empty delimiter is displayed as a broken line in \SpecialChar LyX , but will not show up in the output). \end_layout \begin_layout Standard If you are lazy, you can type actual parentheses in math mode, rather than using the \family sans Math \begin_inset space ~ \end_inset Delimiter \family default dialog. However, those parentheses will be the same size as regular text, which will look bad if you have a big fraction or matrix inside the parentheses. So it is better to use one of the three delimiter buttons that insert them directly, for example \begin_inset Info type "icon" arg "math-delim ( )" \end_inset . \end_layout \begin_layout Standard You can also put delimiters or a square root sign or a decoration on already existing formula parts. Select the portion of the formula that you want to adjust, and then click on the button you want from the \family sans Math \family default toolbar. Try using this to change Newton's second law from scalar to vector form ( \begin_inset Formula $f=ma$ \end_inset to \begin_inset Formula $\overrightarrow{f}=m\overrightarrow{a}$ \end_inset ). Once you have learned about matrices, this is how you will put parentheses or brackets around them. \end_layout \begin_layout Subsection Fractions \end_layout \begin_layout Standard To create a fraction, click on the fraction button \change_deleted -131811572 1566935165 \begin_inset Info type "icon" arg "math-insert \\frac-square" \end_inset \change_inserted -131811572 1566935147 \begin_inset Info type "icon" arg "math-insert \\frac" \end_inset \change_unchanged in the \family sans Math \family default toolbar. \SpecialChar LyX writes two insertion points in a fraction. As you would expect, you can use arrow keys or the mouse to move around a fraction. Click on the top square and type \begin_inset Quotes eld \end_inset 1 \begin_inset Quotes erd \end_inset . Now hit \family sans Down \family default and type \begin_inset Quotes eld \end_inset 2 \begin_inset Quotes erd \end_inset . You have made a fraction! Of course you can type anything within each of the two boxes: variables with exponents, square roots, other fractions, whatever. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Put equation \begin_inset space ~ \end_inset 2 of \change_deleted -712698321 1553351607 \family typewriter example_raw.lyx \change_inserted -712698321 1553351607 \family default \emph on Example (raw) \change_unchanged \emph default into math mode. \end_layout \begin_layout Subsection Functions: lim, log, sin and others \end_layout \begin_layout Standard Because letters in math mode are considered to be variables, if you type \begin_inset Quotes eld \end_inset sin \begin_inset Quotes erd \end_inset in math mode, \SpecialChar LyX thinks you are typing the product of the three variables \begin_inset Formula $s$ \end_inset , \begin_inset Formula $i$ \end_inset , and \begin_inset Formula $n$ \end_inset . The three letters will be typeset in italics, when what you really wanted was the word \begin_inset Quotes eld \end_inset sin \begin_inset Quotes erd \end_inset typeset in Roman. In addition, \SpecialChar LyX will not put a space between the word \begin_inset Quotes eld \end_inset sin \begin_inset Quotes erd \end_inset and the \begin_inset Quotes eld \end_inset x \begin_inset Quotes erd \end_inset (pressing \family sans Space \family default will exit the formula). So how do you get \begin_inset Quotes eld \end_inset \begin_inset Formula $\sin(x)$ \end_inset \begin_inset Quotes erd \end_inset instead of \begin_inset Quotes eld \end_inset \begin_inset Formula $sin(x)$ \end_inset \begin_inset Quotes erd \end_inset ? \end_layout \begin_layout Standard Click on the \family sans Math \family default toolbar button \begin_inset Info type "icon" arg "math-insert \\functions" \end_inset and then on \begin_inset Quotes eld \end_inset sin \begin_inset Quotes erd \end_inset in the pop-up function list. The word \begin_inset Quotes eld \end_inset sin \begin_inset Quotes erd \end_inset is displayed in \SpecialChar LyX in black, and set in upright roman type. The whole word is treated as one symbol, so if you type \family sans Backspace \family default , it will delete the whole word. Now type \begin_inset Quotes eld \end_inset (x) \begin_inset Quotes erd \end_inset , which will be written in blue italics, like you expect in a formula. In the output, the expression will be correctly typeset. Try it out. \end_layout \begin_layout Standard The function list includes other trigonometric functions and their inverses, hyperbolic functions, logarithms, limits, and quite a few others. These functions can take subscripts and superscripts, important for typing \begin_inset Quotes eld \end_inset \begin_inset Formula $\cos^{2}\theta$ \end_inset \begin_inset Quotes erd \end_inset or \begin_inset Quotes eld \end_inset \begin_inset Formula $\lim_{n\rightarrow\infty}$ \end_inset \begin_inset Quotes erd \end_inset . \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Put equation \begin_inset space ~ \end_inset 3 of \change_deleted -712698321 1553351612 \family typewriter example_raw.lyx \change_inserted -712698321 1553351612 \family default \emph on Example (raw) \change_unchanged \emph default into math mode. \end_layout \begin_layout Subsection Matrices \end_layout \begin_layout Standard Click on the matrix button \begin_inset Info type "icon" arg "dialog-show mathmatrix" \end_inset in the \family sans Math \change_inserted -131811572 1566934540 \family default toolbar \change_unchanged . A pop-up dialog allows you to choose how many rows and columns you want in your matrix. Choose 2 rows and 3 columns and hit \family sans OK \family default . \SpecialChar LyX prints 6 insertion points in a \begin_inset Formula $2\times3$ \end_inset matrix. As usual, you can put any sort of formula expression (a square root, another matrix, etc.) in each insertion point. You can also leave some of the insertion points empty if you want. \end_layout \begin_layout Standard \family sans Tab \family default can be used to move horizontally between the columns of a matrix. Alternatively, you can use the arrow keys to move around - hitting \family sans Right \family default at the end of one box will move to the next box, \family sans Down \family default will move to the next row, etc. \end_layout \begin_layout Standard If you need to change the number of rows and columns, use the menu \family sans Edit\SpecialChar menuseparator Rows \begin_inset space \thinspace{} \end_inset & \begin_inset space \thinspace{} \end_inset Columns \family default or the math toolbar buttons \begin_inset Info type "icon" arg "tabular-feature append-row" \end_inset , \begin_inset Info type "icon" arg "tabular-feature delete-row" \end_inset , \begin_inset Info type "icon" arg "tabular-feature append-column" \end_inset , \begin_inset Info type "icon" arg "tabular-feature delete-column" \end_inset . \end_layout \begin_layout Standard See the \emph on User's Guide \emph default for information on how to change the horizontal alignment of each column, and how to change the vertical position of the whole matrix. Note that if you want to write a table containing text, you should use \SpecialChar LyX 's wonderful table support, rather than trying to write text in a matrix. \end_layout \begin_layout Subsection Display mode \end_layout \begin_layout Standard All of the expressions we have written so far have been on the same line as the text that came before and after them, otherwise known as inline expressions. This is fine for short, simple expressions, but if you want to write larger ones, or if you want your expressions to stand out from the text, you need to write them in display mode. In addition, only displayed expressions can be labeled and numbered (see the \emph on User's Guide \emph default ), and multi-line equations must be in display mode. \end_layout \begin_layout Standard While being in a formula, click on the display button \begin_inset Info type "icon" arg "math-display" \end_inset in the \family sans Math \family default toolbar. This centers the formula and adds a blank line before and after it. Now type in an expression and compile your file to see how it looks. The display button is actually a toggle; use it now to change a couple of your expressions to display mode and back. \end_layout \begin_layout Standard Display mode has a couple differences from inline mode: \end_layout \begin_layout Itemize The default font is larger for a few symbols, like \begin_inset Formula $\sum$ \end_inset and \begin_inset Formula $\int$ \end_inset \end_layout \begin_layout Itemize Subscripts and superscripts for limits and sums (but not integrals) are written under and over rather than next to the symbols \end_layout \begin_layout Itemize Text is centered \end_layout \begin_layout Standard Other than these differences, though, displayed expressions and inline expressio ns are very similar. \end_layout \begin_layout Standard One final note about the way displayed formulas are typeset: be careful about whether you are putting your equation into a new paragraph or not. If your formula is in the middle of a sentence or paragraph, then do not press \family sans Return \family default . Doing so will cause the text \emph on after \emph default the formula to start a new paragraph. That text will be indented or follow a blank line, depending on your document paragraph settings, which is probably not what you want. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Put the various equations in \change_deleted -712698321 1553351617 \family typewriter example_raw.lyx \change_inserted -712698321 1553351617 \family default \emph on Example (raw) \change_unchanged \emph default into display mode, and see how they are typeset differently. \end_layout \begin_layout Labeling \labelwidthstring 00.00.0000 \series bold Exercise \series default : Using various tools you have learned in this section, you should be able to write an equation like: \begin_inset Foot status collapsed \begin_layout Plain Layout After you have done it the hard way, give \family sans Insert\SpecialChar menuseparator Math\SpecialChar menuseparator Cases \begin_inset space ~ \end_inset Environment \family default a try. \end_layout \end_inset \begin_inset Formula \[ f(x)=\left\{ \begin{array}{cc} \log_{8}x & x>0\\ 0 & x=0\\ \sum_{i=1}^{5}\alpha_{i}+\sqrt{-\frac{1}{x}} & x<0 \end{array}\right. \] \end_inset \end_layout \begin_layout Section More Math Stuff \end_layout \begin_layout Standard Now you are familiar with the basics. \SpecialChar LyX 's math editor can do a lot more. You can refer to the \emph on Math \emph default manual for tips on how to: \end_layout \begin_layout Itemize Label and number expressions. \end_layout \begin_layout Itemize Create multi-line equations. \end_layout \begin_layout Itemize Change typefaces, e. \begin_inset space \thinspace{} \end_inset g. \begin_inset space \space{} \end_inset to write bold-face text in an expression. \end_layout \begin_layout Itemize Fine-tune font sizes and spacing within an expression. (Do not worry about this until your final draft!) \end_layout \begin_layout Itemize Write macros. These are very powerful, because you just define them once at the top of the document, and then you can use them throughout the document. \end_layout \begin_layout Itemize Do almost all you can do with math. \end_layout \begin_layout Chapter Miscellaneous \end_layout \begin_layout Section Other major \SpecialChar LyX Features \end_layout \begin_layout Standard We have not gone through all the possible commands in \SpecialChar LyX , and we are not planning on it. As usual, see the \emph on User's Guide \emph default and the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manual for more information. We will just mention a couple more major things \SpecialChar LyX can do: \end_layout \begin_layout Itemize \SpecialChar LyX has WYSIWYM support for tables. Use the \family sans Insert\SpecialChar menuseparator Table \family default (toolbar button \begin_inset Info type "icon" arg "tabular-insert" \end_inset ) to get a table. Click on the table with the \emph on right button \emph default to get a \family sans Table \begin_inset space ~ \end_inset Settings \family default dialog box which allows extensive table editing. By pressing \begin_inset Info type "icon" arg "toolbar-toggle table" \end_inset the table toolbar will appear permanently. \end_layout \begin_layout Itemize \SpecialChar LyX also supports including pictures in any format within documents. (You guessed it: \family sans Insert\SpecialChar menuseparator Graphics \family default (toolbar button \begin_inset Info type "icon" arg "dialog-show-new-inset graphics" \end_inset ). Then browse for the figure file, rotate or scale it, etc.) Tables and figures can have captions, and \SpecialChar LyX will automatically generate lists of figures and/or tables. \end_layout \begin_layout Itemize \SpecialChar LyX is heavily configurable. Everything from how the \SpecialChar LyX window looks to how the output comes out can be configured in a number of ways. Much configuration is done through \family sans Tools\SpecialChar menuseparator Preferences \family default . For more information on this, check out \family sans Help\SpecialChar menuseparator Customization\SpecialChar endofsentence \end_layout \begin_layout Itemize \SpecialChar LyX is being developed by a team of programmers on five continents. Therefore, \SpecialChar LyX has better support for non-English languages (such as Dutch, German, French, Greek, Czech, Turkish, \SpecialChar ldots ) than many word processors. Even the right-to-left languages Arabic, Farsi, and Hebrew and the Asian languages Chinese Japanese, and Korean are supported. You can write documents in other languages and you can also configure \SpecialChar LyX to show its menus and error messages in other languages. \end_layout \begin_layout Itemize The \SpecialChar LyX menus feature keybindings. This means that you can do \family sans File\SpecialChar menuseparator Open \family default by pressing \family sans Alt+F \family default followed by \family sans O \family default or by using the binding which is shown next to it in the menu ( \begin_inset Info type "shortcut" arg "file-open" \end_inset by default). Keybindings are also configurable. For information on this, check out \family sans Help\SpecialChar menuseparator Customization\SpecialChar endofsentence \end_layout \begin_layout Itemize \SpecialChar LyX can read \SpecialChar LaTeX documents. See section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:tex2lyx" \end_inset . \end_layout \begin_layout Itemize Spell-checking, thesaurus, and word count facilities are available. \end_layout \begin_layout Itemize Generation of indexes and nomenclatures/glossaries is supported. \end_layout \begin_layout Section \SpecialChar LyX for \SpecialChar LaTeX Users \begin_inset CommandInset label LatexCommand label name "sec:latexusers" \end_inset \end_layout \begin_layout Standard If you do not know anything about \SpecialChar LaTeX , you do not have to read this section. Actually, you might want to \emph on learn \emph default about \SpecialChar LaTeX , and then read this chapter. However, some of those who begin to use \SpecialChar LyX will be familiar with \SpecialChar LaTeX . If you are such a person, you may be wondering if \SpecialChar LyX can really do everything \SpecialChar LaTeX can do. The short answer is that \SpecialChar LyX can do pretty much everything \SpecialChar LaTeX can do in one form or another, and it definitely simplifies most parts of writing a \SpecialChar LaTeX document. \end_layout \begin_layout Standard Because this is just a tutorial, we are only going to mention things that new \SpecialChar LyX users will most likely be interested in. In the interests of keeping the Tutorial short, we will give only minimal information here. The \emph on Additional \begin_inset space ~ \end_inset Features \emph default and the \emph on Embedded \begin_inset space ~ \end_inset Objects \emph default manuals have a great deal of information on differences between \SpecialChar LyX and \SpecialChar LaTeX , and how to do various \SpecialChar LaTeX tricks in \SpecialChar LyX . \end_layout \begin_layout Subsection \SpecialChar TeX Mode \end_layout \begin_layout Standard Anything that you enter in \SpecialChar TeX mode will be passed straight to \SpecialChar LaTeX , and will be displayed in red on the screen. You can use \SpecialChar TeX commands in \SpecialChar LyX by choosing \family sans Insert\SpecialChar menuseparator TeX \begin_inset space ~ \end_inset Code \family default (toolbar button \begin_inset Info type "icon" arg "ert-insert" \end_inset ). This creates a box where everything within it is passed straight to \SpecialChar LaTeX . \end_layout \begin_layout Standard In a math formula, \SpecialChar TeX mode is handled a bit differently. \SpecialChar TeX mode is entered there by typing a backslash. The backslash is not written out, but anything you type afterwards will be in red. You exit \SpecialChar TeX mode by typing \family sans Space \family default or some other non-alphabetic character, like a number, underscore, caret or parenthesis. Once you exit \SpecialChar TeX mode, if \SpecialChar LyX knows the \SpecialChar TeX command you have typed in, it will convert it to WYSIWYM\SpecialChar endofsentence So if you type \begin_inset Quotes eld \end_inset \family typewriter \backslash gamma \family default \begin_inset Quotes erd \end_inset in a formula and then press \family sans Space \family default , \SpecialChar LyX will change the red \begin_inset Quotes eld \end_inset gamma \begin_inset Quotes erd \end_inset to a blue \begin_inset Quotes eld \end_inset \begin_inset Formula $\gamma$ \end_inset \begin_inset Quotes erd \end_inset . This will work for almost all, non-complicated math macros. This may be faster than using the \family sans Math \begin_inset space ~ \end_inset Toolbar \family default , and will be especially convenient for experienced \SpecialChar LaTeX users. \end_layout \begin_layout Standard As a special case, if you type \begin_inset Quotes eld \end_inset \family typewriter \backslash { \family default \begin_inset Quotes erd \end_inset in a formula, the beginning \emph on and \emph default ending braces will be inserted in red while the cursor is placed between the braces. This makes it more convenient to type those commands that take an argument. \end_layout \begin_layout Standard \SpecialChar LyX cannot do absolutely everything that \SpecialChar LaTeX can do. Some fancy functions are not supported at all, while some work but are not WYSIWYM. \SpecialChar TeX mode allows users to get the full flexibility of \SpecialChar LaTeX , while having all the convenient features of \SpecialChar LyX , like WYSIWYM math, tables, and editing. \SpecialChar LyX could never support every \SpecialChar LaTeX package. However, by typing \family typewriter \backslash usepackage{foo} \family default in the preamble (see Section \begin_inset space ~ \end_inset \begin_inset CommandInset ref LatexCommand ref reference "sec:preamble" \end_inset ), you can use any package you want — although you will not have WYSIWYM support for that package's features. \end_layout \begin_layout Subsection Importing \SpecialChar LaTeX Documents — \family typewriter tex2lyx \family default \begin_inset CommandInset label LatexCommand label name "sec:tex2lyx" \end_inset \end_layout \begin_layout Standard You can import a \SpecialChar LaTeX file into \SpecialChar LyX by using the \family sans File\SpecialChar menuseparator Import\SpecialChar menuseparator LaTeX \begin_inset space ~ \end_inset (plain) \family default menu in \SpecialChar LyX . This will call the program \family typewriter tex2lyx \family default which will create a file foo.lyx from the file foo.tex. \SpecialChar LyX will then open that file. If the translation does not work, you can try calling \family typewriter tex2lyx \family default from the command line, possibly using fancier options. \end_layout \begin_layout Standard Even when the translation does work, \family typewriter tex2lyx \family default may not translate everything, though it does handle most legal \SpecialChar LaTeX . It will leave things it does not understand in \SpecialChar TeX mode; so, after translating a file with \family typewriter tex2lyx \family default , you can look for the red text and manually edit it to get it right. \end_layout \begin_layout Standard \family typewriter tex2lyx \family default has its own documentation (manpage), which Unix/Linux users can access via the console command \family typewriter man \begin_inset space ~ \end_inset tex2lyx \family default . The manpage describes which \SpecialChar LaTeX commands and environments are not supported, what bugs you might run into (and how to get around them), and how to use the various options. \end_layout \begin_layout Standard It is important to understand that \family typewriter tex2lyx \family default can only translate files whose document class is \begin_inset Quotes eld \end_inset known \begin_inset Quotes erd \end_inset to \SpecialChar LyX , that is, for which there is a corresponding \SpecialChar LyX \family sans layout file \family default . If there is no layout file, then you will get an error saying that the conversion could not be performed. So, unless you have a layout for the document class of your \SpecialChar LaTeX file, \family typewriter tex2lyx \family default simply will not know how to translate the \SpecialChar LaTeX that it finds there into things \SpecialChar LyX understands. More about layout files and how they are created is explained in detail in Chapter 5 of the \emph on Customization \emph default manual. \end_layout \begin_layout Subsection Converting \SpecialChar LyX Documents to \SpecialChar LaTeX \end_layout \begin_layout Standard You might wish to convert a \SpecialChar LyX Document to a \SpecialChar LaTeX file. For example, a co-worker or co-author who does not have \SpecialChar LyX might want to read it. Select \family sans File\SpecialChar menuseparator Export\SpecialChar menuseparator LaTeX \family default .
