Introduction
\end_layout
\begin_layout Section
Welcome to \SpecialChar LyX
!
\end_layout
\begin_layout Standard
This manual is designed for all of you who have never heard of \SpecialChar LaTeX
, or do not
know it very well.
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

\emph default
, you should definitely check out Section

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

This is very simple:
\series default
Start up \SpecialChar LyX
, select the
\emph on

\emph default
from the
\family sans
Help
\family default
menu.
You may want to load the

already).
This way, you can read them while you are writing your own file.

They can also serve as good examples of how to use the many features of
\SpecialChar LyX
.
\end_layout

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

\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

\end_inset
),
\family sans
Edit\SpecialChar menuseparator
Copy
\family default
(toolbar button
\begin_inset Info

\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

\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

If you change one of your section headings to the

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

\family default
environment, where each item in the list begins with a bold-faced word.
\end_layout
\begin_layout Itemize
The
\family sans

\family default

\family sans

\family default

\family sans

\family default

\end_layout
\begin_layout Standard
Let us write a list of reasons why \SpecialChar LyX

\begin_inset Info

\end_inset

\SpecialChar LyX

Type in your reasons:
\end_layout
\begin_layout LyX-Code

\end_layout
\begin_layout LyX-Code

\end_layout
\begin_layout LyX-Code

\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

\emph default
, one way is to use the

\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

\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

But what if you wanted to number the reasons? Well, just select the whole
list
\begin_inset Foot

\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

\family default
from the
\family sans

Pow! As we mentioned, if you add or delete a list item, \SpecialChar LyX

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

The term is either typeset in boldface (

\begin_layout Chapter
Writing Documents
\end_layout
\begin_layout Standard
The previous chapter hopefully allowed you to get used to writing in \SpecialChar LyX
.
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

\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

\begin_inset Foot

\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.

\begin_layout Section
Templates: Writing a Letter
\end_layout
\begin_layout Standard
One way to write a letter would be to open a new file, and choose a
\family sans
Letter
\family default
class in the
\family sans
Document\SpecialChar menuseparator
Settings
\family default
dialog.
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

\family default
\emph on
Letter (Standard Class)
\change_unchanged
\emph default
as the template.
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.

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

\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.

Now let us change
\begin_inset Formula $E=mc^{2}$

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

\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

However, you can also use the arrow keys.

\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

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

\end_inset
and the
\begin_inset Quotes eld
\end_inset

So how do you get
\begin_inset Quotes eld
\end_inset
\begin_inset Formula $\sin(x)$
\end_inset
\begin_inset Quotes erd

instead of
\begin_inset Quotes eld

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

, it will delete the whole word.
Now type
\begin_inset Quotes eld
\end_inset

In the output, the expression will be correctly typeset.
Try it out.
\end_layout

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

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.

If you are such a person, you may be wondering if \SpecialChar LyX
can really do everything
\SpecialChar LaTeX

TeX
\begin_inset space ~
\end_inset
Code
\family default

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

\begin_inset Quotes erd
\end_inset
to a blue
\begin_inset Quotes eld
\end_inset
\begin_inset Formula $\gamma$

This will work for almost all, non-complicated math macros.
This may be faster than using the

\begin_layout Standard
As a special case, if you type
\begin_inset Quotes eld
\end_inset
\family typewriter

{
\family default
\begin_inset Quotes erd
\end_inset
in a formula, the beginning
\emph on

the braces.
This makes it more convenient to type those commands that take an argument.

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.

\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

This will create a file
