+ * @take_focus: %TRUE if the menu shell should take the keyboard focus on popup.
+ *
+ * If @take_focus is %TRUE (the default) the menu shell will take the keyboard
+ * focus so that it will receive all keyboard events which is needed to enable
+ * keyboard navigation in menus.
+ *
+ * Setting @take_focus to %FALSE is useful only for special applications
+ * like virtual keyboard implementations which should not take keyboard
+ * focus.
+ *
+ * The @take_focus state of a menu or menu bar is automatically propagated
+ * to submenus whenever a submenu is popped up, so you don't have to worry
+ * about recursively setting it for your entire menu hierarchy. Only when
+ * programmatically picking a submenu and popping it up manually, the
+ * @take_focus property of the submenu needs to be set explicitely.
+ *
+ * Note that setting it to %FALSE has side-effects:
+ *
+ * If the focus is in some other app, it keeps the focus and keynav in
+ * the menu doesn't work. Consequently, keynav on the menu will only
+ * work if the focus is on some toplevel owned by the onscreen keyboard.
+ *
+ * To avoid confusing the user, menus with @take_focus set to %FALSE
+ * should not display mnemonics or accelerators, since it cannot be
+ * guaranteed that they will work.
+ *
