ncurses, at least in normal use, takes over the terminal screen.
That's fine for something like a text editor or file viewer, but
it's overkill for a program that just wants to detect F1 on input.

The sequence sent by F1 can vary depending on what kind of terminal
you're using, though (almost?) all terminal emulators these days
use VT100-like sequences by default.

There's probably a clean way to handle function keys on UNIX-like
systems without resorting to ncurses.  comp.unix.programmer would
be a good place to ask.
