/**
* SECTION:gtkactiongroup
* @Short_description: A group of actions
* @Title: GtkActionGroup
*
* 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
* <literal>&lt;Actions&gt;/group-name/action-name</literal>)
* 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 &lt;child&gt; 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 &lt;accelerator&gt; element, which has attributes named key and
* modifiers and allows to specify accelerators. This is similar to the
* &lt;accelerator&gt; element of #GtkWidget, the main difference is that
* it doesn't allow you to specify a signal.
*
* ## A #GtkDialog UI definition fragment. ##
