[TxMt] Help with RegEx in Bundles

[Edmundo Ortega]

Thanks a lot Allen, I'm learning a LOT about regex today. The problem  
I'm running into now is that while the captures work, they don't  
allow color coding to continue on to the non-captured items.

So if my function is like this:

     public function addItem(name: String, item: MenuItem): Void {

Then I want my other color coding rules to properly color "String"  
and "MenuItem". But it seems as these are left as source code. I  
assume it's because this string has already been processed and it  
would take innumerable multiple passes to make it work as I wish.

Unless I'm missing another important aspect of the coloring  
functionality. Thanks again!
