+/* Terminology:
+ *
+ * A menu item can be "selected", this means that it is displayed
+ * in the prelight state, and if it has a submenu, that submenu
+ * will be popped up.
+ *
+ * A menu is "active" when it is visible onscreen and the user
+ * is selecting from it. A menubar is not active until the user
+ * clicks on one of its menuitems. When a menu is active,
+ * passing the mouse over a submenu will pop it up.
+ *
+ * menu_shell->active_menu_item, is however, not an "active"
+ * menu item (there is no such thing) but rather, the selected
+ * menu item in that MenuShell, if there is one.
+ *
+ * There is also is a concept of the current menu and a current
+ * menu item. The current menu item is the selected menu item
+ * that is furthest down in the heirarchy. (Every active menu_shell
+ * does not necessarily contain a selected menu item, but if
+ * it does, then menu_shell->parent_menu_shell must also contain
+ * a selected menu item. The current menu is the menu that
+ * contains the current menu_item. It will always have a GTK
+ * grab and receive all key presses.
+ *
+ *
+ * Action signals:
+ *
+ * ::move_current (GtkMenuDirection *dir)
+ * Moves the current menu item in direction 'dir':
+ *
+ * GTK_MENU_DIR_PARENT: To the parent menu shell
+ * GTK_MENU_DIR_CHILD: To the child menu shell (if this item has
+ * a submenu.
+ * GTK_MENU_DIR_NEXT/PREV: To the next or previous item
+ * in this menu.
+ *
+ * As a a bit of a hack to get movement between menus and
+ * menubars working, if submenu_placement is different for
+ * the menu and its MenuShell then the following apply:
+ *
+ * - For 'parent' the current menu is not just moved to
+ * the parent, but moved to the previous entry in the parent
+ * - For 'child', if there is no child, then current is
+ * moved to the next item in the parent.
+ *
+ *
+ * ::activate_current (GBoolean *force_hide)
+ * Activate the current item. If 'force_hide' is true, hide
+ * the current menu item always. Otherwise, only hide
+ * it if menu_item->klass->hide_on_activate is true.
+ *
+ * ::cancel ()
+ * Cancels the current selection
