40  * A #GtkAccelGroup represents a group of keyboard accelerators,
41  * typically attached to a toplevel #GtkWindow (with
42  * gtk_window_add_accel_group()). Usually you won’t need to create a
43  * #GtkAccelGroup directly; instead, when using #GtkUIManager, GTK+
44  * automatically sets up the accelerators for your menus in the ui
45  * manager’s #GtkAccelGroup.
46  * 
47  * Note that “accelerators” are different from
48  * “mnemonics”. Accelerators are shortcuts for
49  * activating a menu item; they appear alongside the menu item they’re a
50  * shortcut for. For example “Ctrl+Q” might appear alongside the “Quit”
51  * menu item. Mnemonics are shortcuts for GUI elements such as text
52  * entries or buttons; they appear as underlined characters. See
53  * gtk_label_new_with_mnemonic(). Menu items can have both accelerators
54  * and mnemonics, of course.
