<h3>Other BBCode Methods</h3>
Find <code>[sourcecode language='css']code here[/sourcecode]</code> too long to type? Here’s some alternative examples:
<ul>
<li><code>[source language='css']code here[/source]</code></li>
<li><code>[code language='css']code here[/code]</code></li>
<li><code>[sourcecode lang='css']code here[/sourcecode]</code></li>
<li><code>[source lang='css']code here[/source]</code></li>
<li><code>[code lang='css']code here[/code]</code></li>
<li><code>[sourcecode='css']code here[/sourcecode]</code></li>
<li><code>[source='css']code here[/source]</code></li>
<li><code>[code='css']code here[/code]</code></li>
<li><code>[lang='css']code here[/lang]</code></li>
<li><code>[css]code here[/css]</code> (or any of the supported language)</li>
</ul>
Note: Quotation marks around the language can be omitted for even shorter and neater syntax. 🙂

There are other good syntax highlighter plugins, but I wanted something simple and fast and 
be able to add the highlight classes with a select box in the TinyMCE editor.
I added some default languages: Javascript, PHP, Python, C, C#, VB.NET, SQL and CSS but you can 
easily add other ones.

Simple Fast Highlighter

Fast syntax highlighter written in Javascript.
