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 gtk:action-set-accel-group function 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.
