* @Title: Accelerator Groups
* @See_also: gtk_window_add_accel_group(), gtk_accel_map_change_entry(),
* gtk_label_new_with_mnemonic()
*
* A #GtkAccelGroup represents a group of keyboard accelerators,
* typically attached to a toplevel #GtkWindow (with
* gtk_window_add_accel_group()).
*
* Note that “accelerators” are different from
* “mnemonics”. Accelerators are shortcuts for
* activating a menu item; they appear alongside the menu item they’re a
* shortcut for. For example “Ctrl+Q” might appear alongside the “Quit”
* menu item. Mnemonics are shortcuts for GUI elements such as text
* entries or buttons; they appear as underlined characters. See
* gtk_label_new_with_mnemonic(). Menu items can have both accelerators
* and mnemonics, of course.
