I have an app that registers event handlers for keydown and looks for keyCode for arrow keys on keyboard. The problem is that the default action is to scroll the window if there is overflow. This is not necessary or useful in this application, and is a distraction.

How do I use returnValue to prevent this default action?
Or do I also need cancelBubble = true?

Code:

                else if(document.attachEvent)
                  {
                   document.attachEvent('onkeydown', function() { if(OBJ.gameOn) OBJ.keySwap(window.event, OBJ); });
                   window.event.returnValue = false; //// this does not seem to  do it.
                   window.event.cancelBubble = true; //// nor this
                  }

Thank you for time and attention.
