Re: Should event and accessKey timing respect preventDefault?

I think I agree with Jack. IIRC, the behavior Brian describes might be appropriate after a cancelPropagate() call, but not after preventDefault(). Apologies if I have the method names wrong - am citing from memory.

I haven't looked closely at preventDefault (up until 2 minutes ago:-), but my impression is that it it should the opposite from what you suggest.
You seem to suggest
    someone calls event->preventDefault(), therefore the default action for the event on its target node doesn't happen.

My understanding is
  if the event comes in, and the target node decides not to take the default action for some reason, then it should also call event->preventDefault().

If my understanding is correct then I think there is no issue. Otherwise, could you point me to some references?
