1898 * <literal>"<Gnumeric-Sheet>/File/New"</literal> and <literal>"<Gnumeric-Sheet>/File/Exit"</literal>.
1900 * Assigning accel paths to menu items then enables the user to change
1901 * their accelerators at runtime. More details about accelerator paths
1902 * and their default setups can be found at gtk_accel_map_add_entry().
