is not cancelable, so I cannot prevent the keystrokes. For example,
I'm using a TextInput control. I can handle the textInput event and
cancel it (not allow the new text to be input) using the
prevenDefault() method. However, the keyDown and keyUp events are
not cancelable. Hence I cannot prevent my user from deleting text
from the control via the DELETE key. The stopPropagation() and
stopImmediatePropagation() method do not work since the event has
already been processed and the text deleted by the time it gets to
the keyDown and keyUp events. It seems that there must be someway
to be able to reject or respond in a custom way to keyDown/keyUp
events???
