+.SH NAME
+\fBkeyok\fP \- enable or disable a keycode
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint keyok(int keycode, bool enable);\fP
+.SH DESCRIPTION
+This is an extension to the curses library.
+It permits an application to disable specific keycodes, rather than
+use the \fIkeypad\fP function to disable all keycodes.
+Keys that have been disabled can be reenabled.
+.SH RETURN VALUE
+The keycode must be greater than zero, else ERR is returned.
+If it does not correspond to a defined key, then ERR is returned.
+If the \fIenable\fP parameter is true, then the key must have been disabled,
+and vice versa.
+Otherwise, the function returns OK.
+.SH PORTABILITY
+These routines are specific to ncurses.  They were not supported on
+Version 7, BSD or System V implementations.  It is recommended that
+any code depending on them be conditioned using NCURSES_VERSION.
+.SH SEE ALSO
