/**
* GtkShortcutsWindow:
*
* A `GtkShortcutsWindow` shows information about the keyboard shortcuts
* and gestures of an application.
*
* The shortcuts can be grouped, and you can have multiple sections in this
* window, corresponding to the major modes of your application.
*
* Additionally, the shortcuts can be filtered by the current view, to avoid
* showing information that is not relevant in the current application context.
*
* The recommended way to construct a `GtkShortcutsWindow` is with
* [class@Gtk.Builder], by using the `<child>` tag to populate a
* `GtkShortcutsWindow` with one or more [class@Gtk.ShortcutsSection] objects,
* which contain one or more [class@Gtk.ShortcutsGroup] instances, which, in turn,
* contain [class@Gtk.ShortcutsShortcut] instances.
*
* If you need to add a section programmatically, use [method@Gtk.ShortcutsWindow.add_section]
* instead of [method@Gtk.Window.set_child], as the shortcuts window manages
* its children directly.
*
* # A simple example:
*
* ![](gedit-shortcuts.png)
*
* This example has as single section. As you can see, the shortcut groups
* are arranged in columns, and spread across several pages if there are too
* many to find on a single page.
*
* The .ui file for this example can be found [here](https://gitlab.gnome.org/GNOME/gtk/tree/main/demos/gtk-demo/shortcuts-gedit.ui).
*
* # An example with multiple views:
*
* ![](clocks-shortcuts.png)
*
* This example shows a `GtkShortcutsWindow` that has been configured to show only
* the shortcuts relevant to the "stopwatch" view.
*
* The .ui file for this example can be found [here](https://gitlab.gnome.org/GNOME/gtk/tree/main/demos/gtk-demo/shortcuts-clocks.ui).
*
* # An example with multiple sections:
*
* ![](builder-shortcuts.png)
*
* This example shows a `GtkShortcutsWindow` with two sections, "Editor Shortcuts"
* and "Terminal Shortcuts".
*
* The .ui file for this example can be found [here](https://gitlab.gnome.org/GNOME/gtk/tree/main/demos/gtk-demo/shortcuts-builder.ui).
*
* ## CSS nodes
*
* `GtkShortcutsWindow` has a single CSS node with the name `window` and style
* class `.shortcuts`.
