Re: Adding Event Handlers on the body element...

You can try something like this:

Event.addNativePreviewHandler(new NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent event) {
int KEY_F8 = 119;
if ("keyup".equals(event.getNativeEvent().getType()) &&
event.getNativeEvent().getKeyCode() == KEY_F8) {
// do something onkeyup && f8
}
}
});
