<p>
You can insert some special commands into the source of your documents. A command is a word preceded by the character `<tt>\\</tt>'. The command may have one or more arguments, which must be enclosed in pairs of braces `<tt>{ }</tt>'. Two syntaxes are possible for the arguments:
<p><ul>
<li>Either <tt>\\command{argument1}{argument2}{argument3}...</tt> ,
<li>Or <tt>\\command{argument1,argument2,argument3}...</tt> .
</ul><p>

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 <tt>&amp;#44;</tt>.
<p>
