       menu_opts_off; see menu_opts(3x)), the menu becomes multi-valued;  that
       is, more than one item may simultaneously be selected.

       In a multi_valued menu, you can used set_item_value to select the given
       menu item (second  argument  TRUE)  or  deselect  it  (second  argument
       FALSE).
