How to detect if the delete key was pressed in Actionscript 3?

Question

How do I determine if the delete key was pressed using actionscript?

addEventListener(KeyboardEvent.KEY_UP, onKeyUp);

...

function onKeyUp(event:KeyboardEvent):void
{
    trace(event.keyCode);
}

The above code yields no value when delete, backspace, enter, and other command keys are pressed. However, arrow keys do yield values.

Answer 1

this.stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyPressed);
....

function onKeyPressed(event:KeyboardEvent):void
{
   if (event.keyCode==Keyboard.DELETE) {
       .....
       }

}

it's workin nice... But if you test movie from Flash, it will not work, so export to swf and test....
