/**
* GtkShortcutsGroup :
*
* A ` GtkShortcutsGroup ` represents a group of related keyboard shortcuts
* or gestures .
*
* The group has a title . It may optionally be associated with a view
* of the application , which can be used to show only relevant shortcuts
* depending on the application context .
*
* This widget is only meant to be used with [ class @ Gtk . ShortcutsWindow ] .
*
* The recommended way to construct a ` GtkShortcutsGroup ` is with
* [ class @ Gtk . Builder ] , by using the ` < child > ` tag to populate a
* ` GtkShortcutsGroup ` with one or more [ class @ Gtk . ShortcutsShortcut ]
* instances .
*
* If you need to add a shortcut programmatically , use
* [ method @ Gtk . ShortcutsGroup . add_shortcut ] .
*
* Deprecated : 4 . 18 : This widget will be removed in GTK 5
