Unless Marshall is using BSD curses.  I, also, am writing an application
which requires the use of arrow keys, but I am using BSD curses.  There
is nothing in the man page about using the arrow keys, because there is
no keypad() function, and hence no standardized way of using the arrow
keys with BSD curses.

I be able to answer Marshall's questions (relative to Berkeley curses) in
the next week or so, as soon as I do a little more research into this
dilemma.  If anyone is interested, I will post what I find.
