2015-09-24 22:00:03 +00:00
Welcome to \SpecialChar LyX
!
\end_layout
\begin_layout Standard
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
\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
2015-09-24 22:00:03 +00:00
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.
2015-09-24 22:00:03 +00:00
\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
2015-09-24 22:00:03 +00:00
So read on to learn more about \SpecialChar LyX
.
Reading this tutorial is definitely worth the time.

\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

\emph default
manual.
If you came to this manual first, please read the
\emph on

before you continue with the

Now that you know which fonts mean what in the documentation, we want to

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
2015-09-24 22:00:03 +00:00
If you are familiar with \SpecialChar LaTeX
, you will probably be able to read the
\emph on
Tutorial
\emph default
2015-09-24 22:00:03 +00:00
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

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
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
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.

They can also serve as good examples of how to use the many features of
2015-09-24 22:00:03 +00:00
\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
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
as on Windows, where this is setup by the \SpecialChar LyX
installers.
\end_layout
\begin_layout Standard
Finally, we have written a file called
\family typewriter
example_raw.lyx
\family default
2015-09-24 22:00:03 +00:00
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
\family typewriter
example_raw.lyx
\family default
.
It also contains `subtle' hints about how to fix things.

\end_layout
\end_inset
If you want to cheat, or check what you have done, there is also a file
called
\family typewriter
example_lyxified.lyx
\family default
2015-09-24 22:00:03 +00:00
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 the
\family typewriter
examples
\family default
2015-09-24 22:00:03 +00:00
directory of \SpecialChar LyX
's installation folder.
Open the document

and use

2015-09-24 22:00:03 +00:00
File\SpecialChar menuseparator
Save

As

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, the
\family typewriter
examples
\family default
directory contains lots of other examples files.
2015-09-24 22:00:03 +00:00
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.

WYSIWYM: Whitespace in \SpecialChar LyX
\end_layout
\begin_layout Standard
2015-09-24 22:00:03 +00:00
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.
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
\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
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
\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

\begin_layout Standard
Different parts of a document have different purposes; we call these parts

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.

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.
2015-09-24 22:00:03 +00:00
\SpecialChar LyX
lets you avoid learning all the different formatting styles.

\begin_layout Standard
2015-09-24 22:00:03 +00:00
\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

Somewhere in your document, type:

\begin_inset Info

\end_inset

2015-09-24 22:00:03 +00:00
\SpecialChar LyX
writes a
\begin_inset Quotes eld
\end_inset

Type in your reasons:
\end_layout

List environments, unlike headings, do not end when you type
\family sans

\family default

2015-09-24 22:00:03 +00:00
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

\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.
2015-09-24 22:00:03 +00:00
You might want to run \SpecialChar LaTeX

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

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

Pow! As we mentioned, if you add or delete a list item, \SpecialChar LyX
will fix the numbering.

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 (

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.

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.

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_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
2015-09-24 22:00:03 +00:00
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.
2015-09-24 22:00:03 +00:00
\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
2015-09-24 22:00:03 +00:00
File\SpecialChar menuseparator
New
\begin_inset space ~
\end_inset
from
\begin_inset space ~
\end_inset
Template
\family default
.
Select
\family typewriter
letter.lyx
\family 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.
2015-09-24 22:00:03 +00:00
Remember, \SpecialChar LyX
is WYSIWYM; you can put the
\family sans
Signature
\family default
2015-09-24 22:00:03 +00:00
environment anywhere you want, but \SpecialChar LyX
knows that in the printout, the signature
should be at the end.
\end_layout
\begin_layout Standard
2015-09-24 22:00:03 +00:00
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
here; just write a letter to someone!

\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.
2015-09-24 22:00:03 +00:00
Finally, they may be useful for a person who is configuring \SpecialChar LyX
for a bunch
of less computer-aware users.
2015-09-24 22:00:03 +00:00
When they are first learning \SpecialChar LyX
, it will be less intimidating if they have
a letter template customized for their company, for example.

You can refer to a section's number, to the page on which the section begins
or to both.
2015-09-24 22:00:03 +00:00
As with section numbering, \SpecialChar LyX
also takes care of cross-reference numbering
for you.

2015-09-24 22:00:03 +00:00
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

2015-09-24 22:00:03 +00:00
Click on a decoration, and \SpecialChar LyX

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

to pop up the
\family sans

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 Quotes erd
\end_inset
2015-09-24 22:00:03 +00:00
(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
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

This is fine for short, simple expressions, but if you want to write larger

to write them in display mode.
In addition, only displayed expressions can be labeled and numbered (see

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

Doing so will cause the text

\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.
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00

This means that you can do

Open
\family default
by pressing

Actually, you might want to
\emph on
learn
\emph default
2015-09-24 22:00:03 +00:00
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.

\SpecialChar TeX

\end_layout
\begin_layout Standard
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
Insert\SpecialChar menuseparator
\SpecialChar TeX
\begin_inset space ~
\end_inset

(toolbar button
\begin_inset Info
type "icon"
arg "ert-insert"
\end_inset
).
2015-09-24 22:00:03 +00:00
This creates a box where everything within it is passed straight to \SpecialChar LaTeX
.
\end_layout
\begin_layout Standard
2015-09-24 22:00:03 +00:00
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.
2015-09-24 22:00:03 +00:00
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.
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
, \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
2015-09-24 22:00:03 +00:00
, 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
2015-09-24 22:00:03 +00:00
\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.
2015-09-24 22:00:03 +00:00
\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"

), you can use any package you want — although you will not have WYSIWYM
support for that package's features.

.
This will call the program
\family typewriter

\family default
which will create a file foo.lyx from the file foo.tex.
2015-09-24 22:00:03 +00:00
\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
2015-09-24 22:00:03 +00:00
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

\family default
.
2015-09-24 22:00:03 +00:00
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
2015-09-24 22:00:03 +00:00
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.
2015-09-24 22:00:03 +00:00
So, unless you have a layout for the document class of your \SpecialChar LaTeX
file,
\family typewriter
tex2lyx
\family default
2015-09-24 22:00:03 +00:00
simply will not know how to translate the \SpecialChar LaTeX

\SpecialChar LyX
understands.
More about layout files and how they are created is explained in detail
