 .SH NAME
 \fB\%keyok\fP \-
-enable or disable a \fIcurses\fR keycode
+enable or disable a \fIcurses\fP function key code
 .SH SYNOPSIS
 .nf
 \fB#include <curses.h>
 .PP
-\fBint keyok(int \fIkeycode\fP, bool \fIenable\fP);
+\fBint keyok(int \fIkey-code\fP, bool \fIbf\fP);
 .fi
 .SH DESCRIPTION
-This is an extension to the \fIcurses\fP library.
-It permits an application to disable specific keycodes, rather than
-use the \fB\%keypad\fP function to disable all keycodes.
-Keys that have been disabled can be re-enabled.
+The
+.B \%keyok
+.I \%ncurses
+extension permits a
+.I curses
+application to disable a function key
+.I key-code
+returned by \fB\%wgetch\fP(3X)
+(wide-character API users:
+\fB\%wget_wch\fP(3X)).
+Key codes that have been disabled can be re-enabled.
+.I bf
+indicates the desired enablement status.
+This operation is more fine-grained than calling \fB\%keypad\fP(3X),
+which affects
+.I all
+function keys.
 .SH RETURN VALUE
-The keycode must be greater than zero, else \fBERR\fP is returned.
-If it does not correspond to a defined key, then \fBERR\fP is returned.
-If the \fIenable\fP parameter is true, then the key must have been disabled,
-and vice versa.
-Otherwise, the function returns \fBOK\fP.
+.B \%keyok
+returns
+.B ERR
+if
+.bP
+.I key-code
+is nonpositive,
+.bP
+.I key-code
+is not a recognized value,
+or
+.bP
+enablement of
+.I key-code
+is already in the desired state.
+.PP
+Otherwise,
+.B \%keyok
+returns
+.BR OK "."
+.SH EXTENSIONS
+.B \%keyok
+is an
+.I \%ncurses
+extension.
 .SH PORTABILITY
-This routine is specific to \fI\%ncurses\fP.
-It was not supported on
-Version 7, BSD or System V implementations.
-It is recommended that
-any code depending on them be conditioned using \fB\%NCURSES_VERSION\fP.
+Applications employing
+.I \%ncurses
+extensions should condition their use on the visibility of the
+.B \%NCURSES_VERSION
+preprocessor macro.
+.PP
+NetBSD
+.I curses
+since 2.0 (2004) supports
+.BR \%keyok "."
