we don't use regular GTK key bindings in ardour. everything is handled
via a custom system that avoids the GTK/Qt/X11 "focus" stupidity.

gtk_widget_set_flags (scrollbar, GTK_CAN_FOCUS);
gtk_widget_set_events (scrollbar, GTK_KEY_PRESS_WHATEVER);
then attach handlers to key press/release events. i believe this will work.
but keep in mind that the focus model in GTK/Qt/X11 is likely to be your
enemy rather than your friend.
