I while back I also wrote a library that corrects for keyboard events by
returning a remapped ascii set. If you notice, keyboard events on IE and
Netcape return different keycodes. I've made one mod to remap them and get
the case right. May I suggest that be corrected as well. Also, there was an
example I sent out that showed how to retrieve tab, shift+alt+del, enter,
and even arrow keys regardless of platform or browser but it was in DynAPI
2.5. I haven't had the time to port it to 3.0 but I believe the code should
be implemented, as keyboard support is rather poor to date.
