.SH DESCRIPTION
.sp
.LP
The \fBkeyname()\fR function returns a string pointer to the key name.   Make a
duplicate copy of the returned string if you plan to modify it.
.sp
.LP
The \fBkey_name()\fR function is similar except that it accepts a wide
character key name.
.sp
.LP
The following table shows the format of the key name based on the input.
