- * gtk_application_add_accelerator:
- * @application: a #GtkApplication
- * @accelerator: accelerator string
- * @action_name: the name of the action to activate
- * @parameter: (allow-none): parameter to pass when activating the action,
- *   or %NULL if the action does not accept an activation parameter
- *
- * Installs an accelerator that will cause the named action
- * to be activated when the key combination specificed by @accelerator
- * is pressed.
- *
- * @accelerator must be a string that can be parsed by gtk_accelerator_parse(),
- * e.g. "<Primary>q" or “<Control><Alt>p”.
- *
- * @action_name must be the name of an action as it would be used
- * in the app menu, i.e. actions that have been added to the application
- * are referred to with an “app.” prefix, and window-specific actions
- * with a “win.” prefix.
- *
- * GtkApplication also extracts accelerators out of “accel” attributes
- * in the #GMenuModels passed to gtk_application_set_app_menu() and
- * gtk_application_set_menubar(), which is usually more convenient
- * than calling this function for each accelerator.
- *
- * Since: 3.4
- *
- * Deprecated: 3.14: Use gtk_application_set_accels_for_action() instead
