1804 * each menu item of this menu, that contains a label describing its purpose,
1805 * automatically gets an accel path assigned. For example, a menu containing
1806 * menu items "New" and "Exit", will, after

1808 * has been called, assign its items the accel paths:
1809 * <literal>"<Gnumeric-Sheet>/File/New"</literal> and <literal>"<Gnumeric-Sheet>/File/Exit"</literal>.
1810 * Assigning accel paths to menu items then enables the user to change
1811 * their accelerators at runtime. More details about accelerator paths
1812 * and their default setups can be found at gtk_accel_map_add_entry().
1814 * Note that @accel_path string will be stored in a #GQuark. Therefore, if you
