if simply getting ascii characters from ncurses is enough, then this
message doesn't matter. but if you start to want to use modifiers
combined with keys (e.g. Alt-a, Ctrl-F1), you need to move beyond the
normal ncurses model.
if you take a look at the ardour ncurses front end "ardour/ksi", you
will find a relatively small app that does something pretty close to
what you are thinking about. the key element is setting up the tty in
medium-raw mode so that you can get actual key events from the
keyboard rather than ASCII chars the way that ncurses normally does.
try browsing CVS at:
http://ardour.org/cgi-bin/viewcvs.cgi/ardour/ksi_ardour/
and take a look at physical_keyboard.cc and ksi.cc to get an idea of
what i am talking about.
