Locking an acelerator group prevents the accelerators contained
within it to be changed during runtime. Refer to
gtk_accel_map_change_entry() about runtime accelerator changes.
If called more than once, @accel_group remains locked until
gtk_accel_group_unlock() has been called an equivalent number
of times.
