 .SH NAME
-\fBkeybound\fP \- return definition of keycode
+\fB\%keybound\fP \-
+get definition of \fIcurses\fR keycode
 .SH SYNOPSIS
-\fB#include <curses.h>\fP
-.sp
-\fBchar * keybound(int keycode, int count);\fP
+.nf
+\fB#include <curses.h>
+.PP
+\fBchar * keybound(int \fIkeycode\fP, int \fIcount\fP);
+.fi
 .SH DESCRIPTION
-This is an extension to the curses library.
+This is an extension to the \fIcurses\fP library.
 It permits an application to determine the string which is defined
 in the terminfo for specific keycodes.
 .SH RETURN VALUE
-The \fIkeycode\fP parameter must be greater than zero, else NULL is returned.
-If it does not correspond to a defined key, then NULL is returned.
+The \fIkeycode\fP parameter must be greater than zero,
+else \fBNULL\fP is returned.
+If it does not correspond to a defined key, then \fBNULL\fP is returned.
 The \fIcount\fP parameter is used to allow the application to iterate
 through multiple definitions, counting from zero.
 When successful,
 the function returns a string which must be freed by the caller.
 .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.
