/**
* SECTION:gtkshortcutswindow
* @Title: GtkShortcutsWindow
* @Short_description: Toplevel which shows help for shortcuts
*
* A GtkShortcutsWindow shows brief 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 GtkBuilder,
* by populating a #GtkShortcutsWindow with one or more #GtkShortcutsSection
* objects, which contain #GtkShortcutsGroups that in turn contain objects of
* class #GtkShortcutsShortcut.
*
* # 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://git.gnome.org/browse/gtk+/tree/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://git.gnome.org/browse/gtk+/tree/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://git.gnome.org/browse/gtk+/tree/demos/gtk-demo/shortcuts-builder.ui).
