Of course, this is not an issue for the Tlf build system as all will be
found.  This is just to compile the file I submitted earlier (note to
the lurkers coming across this in the future).

Nice.  It looks like things are being handled correctly.  My goal is to
get to a point where Tlf can work on the op's terminal of choice by
unifying the key codes as much as possible.

Along with the Alt-keys, I am also interested in keys such as F1-F12,
Shift F1-Shift F12, Backspace, Insert, Delete, Home, End, Page-Up,
Page-Down, and the arrow keys.  On a US 101/104 (so-called Windows
keyboard) keyboard the keys between the main keys and the numeric pad as
well as the keys when Num Lock is off are of interest to me.

Most certainly!

I think I am on my way to help making the Tlf UI more consistent.  I'm
also learning a lot about Ncurses, which has been a goal of mine for
years.  :-)

73, Nate
