The codes you refer to in terminfo are actually strings, whereas the
value KEY_NPAGE is simply a number. A number is much easier for a
computer to handle than just a string.

Keep in mind that there are two major methods for handling terminals:
terminfo and termcap. Some curses systems do not use terminfo at all,
and so that is another reason to create an abstraction layer above
terminfo/termcap: So that a curses program does not need to know what
the underlying terminal access method is, and is thus more portable.

I can't remember every message sent to me. :)

You are correct that these are the codes you should be paying attention
to. My assumption that you were using ncurses was incorrect.

If I remember rightly, slang does not use terminfo, but termcap instead.
I suppose that means you should check for /etc/termcap, and see if you
can find your terminal defined there.

I (and Mikko) was using "octal" (base 8) representation for these
numbers. Octal 412 is hex 0x10a, and 415 is 0x10D. Looking these up in
slang.h, I find:
#define SL_KEY_A3 0x10A
#define SL_KEY_C3 0x10C
I don't know offhand what those keys mean, or why slang wants to treat
your page up/down keys with these codes.

Octal 177777 is the representation for -1, which is an error return from
getch(). I guess that means it doesn't understand what key you pressed?
Anyway, it seems to me that ncurses works the way you expect in this
case, and slang does not. Either way, however, Mutt is not the source
of the problem.
