I'm using a hold browser and i

the same widget i.e. the browser?
Yes, you can subclass and have a callback attached to the
widget. If you want to "filter" shortcuts (that can't be changed in
the base class you would subclass and define your handle() where
you'd test for the event in question and return 0 *before*
you call the handle() method of the base class, for instance
myclass::handle(int e) {
if (e == FL_SHORTCUT && Fl::key() == FL_END)
return 0;
return baseclass::handle();
}
In this case the FL_END keypress would be propagated to any other
widget that "wants" it.
Note: I can't tell if your assumption is correct, but if it is
something like the code above should help.
