gtk-application-remove-accelerator (application name &optional parameter)

application -- a gtk-application instance
name -- a string with the name of the action to activate
parameter -- an optional g-variant parameter to pass when activating the action, or nil, the default, if the action does not accept an activation parameter

Removes an accelerator that has been previously added with the gtk-application-add-accelerator function. The gtk-application-remove-accelerator function has been deprecated since version 3.14 and should not be used in newly written code. Use the gtk-application-accels-for-action function instead.
