/**
* GtkShortcut :
*
* Describes a keyboard shortcut .
*
* It contains a description of how to trigger the shortcut via a
* [ class @ Gtk . ShortcutTrigger ] and a way to activate the shortcut
* on a widget via a [ class @ Gtk . ShortcutAction ] .
*
* The actual work is usually done via [ class @ Gtk . ShortcutController ] ,
* which decides if and when to activate a shortcut . Using that controller
* directly however is rarely necessary as various higher level
* convenience APIs exist on ` GtkWidget ` s that make it easier to use
* shortcuts in GTK .
*
* ` GtkShortcut ` does provide functionality to make it easy for users
* to work with shortcuts , either by providing informational strings
* for display purposes or by allowing shortcuts to be configured .
