59 If you turn off the menu option <STRONG>O_ONEVALUE</STRONG> (e.g., with
60 <STRONG>set_menu_opts</STRONG> or <STRONG>menu_opts_off</STRONG>; see <STRONG><A HREF="menu_opts.3x.html">menu_opts(3x)</A></STRONG>), the
61 menu becomes multi-valued; that is, more than one item may
62 simultaneously be selected.
64 In a multi_valued menu, you can used <STRONG>set_item_value</STRONG> to
65 select the given menu item (second argument <STRONG>TRUE</STRONG>) or dese-
66 lect it (second argument <STRONG>FALSE</STRONG>).
