Adding "copy to clipboard" functionality into code macro

I've been working with the SyntaxHighlighter code formatter a lot lately (http://code.google.com/p/syntaxhighlighter/) and I'm starting to realize how valuable its "copy to clipboard" functionality is. I'm requesting that similar functionality be added into Confluence's

macro.

Basically, this would involve adding a link into the panel that, upon clicking, would copy the contents/body of the code macro onto the system clipboard.

thanks.
