This might be a case where you would need a binding to the GtkBinding widget
(which is in fact the underling implementation for the accelerators (You have
looked at gtk-accel_group, haven't you ?).
Unfortunately, GtkAda does not include this binding yet, this is probably one
of the two or three widgets/files from gtk+ we haven't worked on yet.
You should look at the C file, and see if you think this could help you.
I believe the binding is fairly easy to do.
