Normal widgets will not receive shortcut events when hidden, or any of their
parents is hidden. There are a few events that still go through though, HIDE,
SHOW, ACTIVATE, DEACTIVATE for example.
Shortcut events will ultimately be sent to a custom handler. See: void
Fl::add_handler(Fl_Event_Handler ha); and void Fl_Menu_::global();
