+.SH NAME
+\fBdefine_key\fP \- define a keycode
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint define_key(const char *definition, int keycode);\fP
+.SH DESCRIPTION
+This is an extension to the curses library.
+It permits an application to define keycodes with their corresponding control
+strings, so that the ncurses library will interpret them just as it would
+the predefined codes in the terminfo database.
+.PP
+If the given string is null, any existing definition for the keycode is
+removed.
+Similarly, if the given keycode is negative or zero, any existing string
+for the given definition is removed.
+.SH RETURN VALUE
+The keycode must be greater than zero, else ERR is returned.
+.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.
