B4J Question Reset TextField to previous text?

[markm]

I have a form with several textfields on it. I want to capture Escape so that if it's pressed, the textfield is reset to its previous text. For example, if textfield.text = "Hi, Bob!" and the user starts typing "Hello, Bill" in it but changes his mind and hits ESC, it will reset to "Hi, Bob!". I have done this on forms with a single textfield by setting a reflector to monitor the textfield and then matching the event type. However, setting a reflector and a filtering sub for each textfield seems excessive. Is there a simple way I'm overlooking for a textfield to be reset in the _TextChanged Sub to say "if last key = Escape, Textfield.text = Old"?
