gtk-action-set-accel-group (action group)

action -- a gtk-action object
group -- a gtk-accel-group object or nil

Sets the accelerator group in which the accelerator for this action will be installed. The function gtk-action-set-accel-group has been deprecated since version 3.10 and should not be used in newly written code. Use the g-action interface and the accelerator group on an associated gtk-menu widget instead.
