can I do this:

is there a way to do this?:

private function blah(evt:MouseEvent):void//Mouse over
     //does something to an object (in my case object.alpha -=1),blah)

essentially I want to use the same function (eg function blah) for a variety of objects so as I dont know what the exact term used in setting the event listener was I can’t use it in removeing the event listener.

Big thanks for taking the time!
