## CDOGS Beginner's Guide to LaTex

How to impress with cool math in your abstract.

For the purpose of writing a basic scientific abstract there are two sets of symbols you need to know for LaTeX: those for text mode and those for math mode. This guide will go through the basics of each.

### Text Mode: Accents

So, you want to have an accent on a letter (for example, your name is Josée not Josee), then by example,

You Want: Hi, my name is Josée.
LaTeX: Hi, my name is Jos\'{e}e.
You Want: Øystein
LaTeX: \O{}ystein

The way the command works, is that the backslash, \, tells LaTeX that a command is coming, then you have the command (put an accent, ', over the letter {e}). Here is a list of accents, and the commands that go with them.

### Text Mode: Decorations (bold, italics, underline)

Do you need to put emphasis on a word or are referencing a species? You will then need to use text decorations.

If you want to bold something you use the commands \textbf{...} where your word/phrase is placed within the curly braces. By example,

You Want: Some of the greatest discoveries in science were made by accident.
LaTeX: Some of the \textbf{greatest} discoveries in science were made by accident.

If you want to italicize something you use the commands \emph{...} or \textit{...} where your word/phrase is placed within the curly braces. By example,

You Want: A main target of the longline fishery is bigeye tuna, Thunnus obesus.
LaTeX: A main target of the longline fishery is bigeye tuna, \emph{Thunnus obesus}.
alternatively,
LaTeX: A main target of the longline fishery is bigeye tuna, \textit{Thunnus obesus}.

If you want to underline something you use the commands \underline{...} where your word/phrase is placed within the curly braces. By example,

You Want: Some of the greatest discoveries in science were made by accident.
LaTeX: Some of the greatest discoveries in \underline{science} were made by accident.

### Text Mode: New paragraphs

LaTeX treats tabs, spaces, and single carriage returns the same:

In LaTeX: The quick      brown fox jumped      over the      lazy dog.
Output: The quick brown fox jumped over the lazy dog.

If you want to start a second paragraph (in your abstract), you must have two carriage returns back-to-back:

In LaTeX: The quick brown fox jumped over the lazy dog.
Output: The quick brown fox jumped over the

lazy dog.

Don't worry about tabs at the beginning of paragraphs and such, that will be taken care of by LaTeX later.
