[TxMt] Help with RegEx in Bundles

[Edmundo Ortega]

Doh. Never mind. I just stopped trying to color the parentheses and  
now it works as I wish. Now, from this string:

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

I'm only capturing:

function addItem

And I'm leaving the coloring of the parenthesis and the rest of the  
string to the other rules.
