/**
 * Actions are organised into groups. An action group is essentially a
 * map from names to #GtkAction objects.
 * 
 * All actions that would make sense to use in a particular context
 * should be in a single group. Multiple action groups may be used for a
 * particular user interface. In fact, it is expected that most nontrivial
 * applications will make use of multiple groups. For example, in an
 * application that can edit multiple documents, one group holding global
 * actions (e.g. quit, about, new), and one group per document holding
 * actions that act on that document (eg. save, cut/copy/paste, etc). Each
 * window’s menus would be constructed from a combination of two action
 * groups.
 * 
 * ## Accelerators ## {#Action-Accel}
 * 
 * Accelerators are handled by the GTK+ accelerator map. All actions are
 * assigned an accelerator path (which normally has the form
 * `<Actions>/group-name/action-name`) and a shortcut is associated with
 * this accelerator path. All menuitems and toolitems take on this accelerator
 * path. The GTK+ accelerator map code makes sure that the correct shortcut
 * is displayed next to the menu item.
 * 
 * # GtkActionGroup as GtkBuildable # {#GtkActionGroup-BUILDER-UI}
 * 
 * The #GtkActionGroup implementation of the #GtkBuildable interface accepts
 * #GtkAction objects as <child> elements in UI definitions.
 * 
 * Note that it is probably more common to define actions and action groups
 * in the code, since they are directly related to what the code can do.
 * 
 * The GtkActionGroup implementation of the GtkBuildable interface supports
 * a custom <accelerator> element, which has attributes named “key“ and
 * “modifiers“ and allows to specify accelerators. This is similar to the
 * <accelerator> element of #GtkWidget, the main difference is that
 * it doesn’t allow you to specify a signal.
 * 
 * ## A #GtkDialog UI definition fragment. ##
