or:
switch (event.getCharCode()) {

No. KeyPress deals with characters whereas KeyDown and KeyUp deal with
"physical keys".
Note that the following change will be shipped in the next GWT version
(2.1):
http://gwt-code-reviews.appspot.com/154812
which fixes issue 3753:
http://code.google.com/p/google-web-toolkit/issues/detail?id=3753
But there are many other issues with keyboard events, as the KeyEvent
JavaDoc warns: """The native keyboard events are somewhat a mess
(http://www.quirksmode.org/js/keys.html), we do some trivial
normalization here, but do not attempt any complex patching, so user
be warned."""
