Hook on creating a menu entry?

If you check out the source, you find the following actions related to the modifications of the navigational menus:

Update:

    /**
     * Fires after a navigation menu has been successfully updated.
     *
     * @since 3.0.0
     *
     * @param int   $menu_id   ID of the updated menu.
     * @param array $menu_data An array of menu data.
     */
    do_action( 'wp_update_nav_menu', $menu_id, $menu_data );

Create:

    /**
     * Fires after a navigation menu is successfully created.
     *
     * @since 3.0.0
     *
     * @param int   $term_id   ID of the new menu.
     * @param array $menu_data An array of menu data.
     */
    do_action( 'wp_create_nav_menu', $_menu['term_id'], $menu_data );

Delete:

    /**
     * Fires after a navigation menu has been successfully deleted.
     *
     * @since 3.0.0
     *
     * @param int $term_id ID of the deleted menu.
     */
    do_action( 'wp_delete_nav_menu', $menu->term_id );

I wonder if you mean these hooks?
