/** A Gtk::AccelGroup represents a group of keyboard accelerators, typically
 * attached to a toplevel Gtk::Window (with Gtk::Window::add_accel_group()).
 * Usually you won't need to create a Gtk::AccelGroup directly; instead, gtkmm
 * automatically sets up the accelerators for your menus.  Note that
 * accelerators are different from mnemonics.  Accelerators are shortcuts for
 * activating a menu item; they appear alongside the menu item for which
 * they're a shortcut. 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 the Gtk::Label
 * constructor. Menu items can have both accelerators and mnemonics, of course.
 *
 * You can use Gtk::Window::get_accel_group() to get an accel group for that window,
 * then use it with other widgets too.
