This.onKeyDown isn't triggered by enter

I’ve this in my code:


Key.addListener(this);

this.onKeyDown = function() {
      trace(Key.getCode());
}

which works okay but it dosn’t seem to be triggered when I press the enter key (either the main one or the one on the num pad)

anyone know an event I can use where I can capture an Enter key press? I know you can use on(keyPress “<Enter>”) in a button but I’d like somethin I can use in the MX style of coding

cheers all (-:
