i want syntax highligher

if you click the small grey question mark in the top line of the syntax highlighter in your link:
view plain copy to clipboard print ?

it will show you the info:
http://www.dreamprojections.com/syntaxhighlighter/?ref=about

possibly this one: http://alexgorbatchev.com/SyntaxHighlighter/

possibly ask the plugin author;

i think if you activate version 2, this might still show the copy icon.

or try the older versions: http://alexgorbatchev.com/SyntaxHighlighter/manual/older_versions.html
