Groups of global keyboard accelerators for an entire GtkWindow
A GtkAccelGroup represents a group of keyboard accelerators, typically
attached to a toplevel GtkWindow (with
add_accel_group() ). Usually you won't
need to create a GtkAccelGroup directly; instead, when using
GtkItemFactory, GTK+ automatically sets up the
accelerators for your menus in the item factory's GtkAccelGroup.
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 GtkLabel
constructor. Menu items can have
both accelerators and mnemonics, of course.
