- This is an extension to the <EM>curses</EM> library. It permits an application
- to disable specific keycodes, rather than use the <STRONG>keypad</STRONG> function to
- disable all keycodes. Keys that have been disabled can be re-enabled.
+ The <STRONG>keyok</STRONG> <EM>ncurses</EM> extension permits a <EM>curses</EM> application to disable a
+ function key <EM>key-code</EM> returned by <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG> (wide-character API users:
+ <STRONG><A HREF="curs_get_wch.3x.html">wget_wch(3x)</A></STRONG>). Key codes that have been disabled can be re-enabled.
+ <EM>bf</EM> indicates the desired enablement status. This operation is more
+ fine-grained than calling <STRONG><A HREF="curs_inopts.3x.html">keypad(3x)</A></STRONG>, which affects <EM>all</EM> function keys.
