You can insert some special commands into the source of your documents. A command is a word preceded by the character \\. The command may have one or more arguments, which must be enclosed in pairs of braces { }. Two syntaxes are possible for the arguments:

- Either \\command{argument1}{argument2}{argument3}... ,
- Or \\command{argument1,argument2,argument3}... .

Because commas are used to separate arguments, they cannot appear within an argument. If you want to add a comma into an argument, type the string &#44;.

Here is the list of available commands.
