/**
* SECTION:gtkshortcutmanager
* @title: GtkShortcutManager
* @short_description: Interface for managing shortcuts
*
* The GtkShortcutManager interface is used to implement
* shortcut scopes.
*
* This is important for #GtkNative widgets that have their own surface,
* since the event controllers that are used to implement managed and
* global scopes are limited to the same native.
*
* Examples for widgets implementing #GtkShortcutManager are #GtkWindow
* and #GtkPopover.
