# LaTeXing - Professional Typesetting

An extension for Sublime Text which makes your life
easier and more comfortable while creating your documents.

# Entering TeX Symbols ¶

LaTeXing includes a range of completion snippets, which make entering math symbols very easy. There are two triggers, § and tab, which follow a clear logic: § expands the character(s) around the cursor for example into a corresponding Greek symbol, while tab expands the character(s) left of the cursor into math symbols by using the default auto completion of Sublime Text. In this tutorial will just focus on the § trigger key.

On Windows and Linux the trigger is  and not the § which is used in this tutorial, so just use your right trigger key. Check the sublime-keymap files for the right command, you can also adjust the command in case your keyboard layout variates. If you which to use a different key, for example to adapt a different keyboard layout, you can change the key in the key bindings setting file.

Say you are in an equation environment and want to enter \alpha.

$$a$$


You can expand a into \alpha by either hitting tab or §:

$$\alpha$$


If you now hit § again, nothing happens because no 2nd expansion is available for this Greek symbol and § already expanded to the Greek character alpha. However, if you hit tab behind a single a it would result in the same because it is the best match of the Sublime Text auto completion as well.

The tab trigger lets you choose from a large number of symbols provided from the *.sublime-completions files, while § gives you direct access to the frequently used Greek math characters and symbols. Finally, § lets you quickly enter Greek symbols surrounded by opening and closing $while writing text outside of math environments. If you hit § in this situation LaTeXing will expand a to the following: a[§] will change to$\alpha$ ## Greek characters ¶ Below is a list of currently implemented completions for Greek symbols. When more than one symbol is listed, you can reach it by pressing § repeatedly. Character 1st expansion 2nd exp. 3rd exp. 4th exp. 5th exp. 6th exp. a \alpha b \beta d \delta e \epsilon f \phi g \gamma h \eta i \iota j \theta k \kappa l \lambda m \mu n \nu p \pi \psi r \rho s \sigma t \tau u \upsilon v \varepsilon \varphi \varpi \varrho \varsigma \vartheta w \omega x \xi z \zeta Capital versions of Greek symbols are also available. Character 1st expansion 2nd expansion D \Delta G \Gamma J \Theta L \Lambda O \Omega P \Pi \Psi S \Sigma X \Xi ## Arrows ¶ Arrows are very useful but difficult to remember and long to type, with the § trigger this is very easy and quick to complete. character 1st expansion 2nd expansion <- \leftarrow \longleftarrow <= \Leftarrow \Longleftarrow -> \rightarrow \ronglightarrow => \Rightarrow \Ronglightarrow <-> \leftrightarrow \longleftrightarrow <=> \Leftrightarrow \Longleftrightarrow You can expand -> into \rightarrow by either hitting §: $$->$$  If you now hit § again, nothing happens, if no 2nd expansion is available. However, this is also working outside of math environments and LaTeXing surround the command by opening and closing \$.

$$\rightarrow$$


## Other quick symbol shortcuts ¶

Some commonly used math symbols (such as dots) are accessible via § trigger as well (as always, further expansions can be reached via § trigger).

Character 1st expansion 2nd expansion
( \left(
) \right)
[ \left[
] \right]
| \left| \right|
/ \left/ \right/
. \dots
* \times
< \leq
> \geq

Outside of math environments < and > will expand to \textless and \textgreater

## Simultaneously enter open and closing parentheses ¶

Using tab or § trigger you can enter open and closing parentheses more quickly. Say you want to enter parentheses that adapt to the size of their content, pressing one trigger when the cursor is within parentheses

$$()$$


expands to

$$\left(\right)$$


This works for square brackets and curly braces as well.

# Menu of symbols and commands ¶

There are too many math symbols and commands to memorize them all. Thus LaTeXing can provide you with a menu to choose from. When in an empty math environment pressing §` on its own (i.e., without a preceding character) opens a menu of available categories:

Entering a categories (press [enter]) allows you to choose from a range of symbols and commands. You can also disable the list in categories with disable the setting symbols_in_category.
