Quite bored of crankys posts, so I hope he will not. I suggest he would read
documentation for once, if he had done that he may have read the following:
Quoted from the ncurses_programming_howto:
Normally the terminal driver buffers the characters a user types until a new
line or carriage return is encountered. But most programs require that the
characters be available as soon as the user types them. The above two
functions are used to disable line buffering. The difference between these two
functions is in the way control characters like suspend (CTRL-Z), interrupt
and quit (CTRL-C) are passed to the program. In the raw() mode these
characters are directly passed to the program without generating a signal. In
the cbreak() mode these control characters are interpreted as any other
character by the terminal driver.
I guess his program is waiting for a return which you don't get when you just
press a function key.
As he is a gnome2 fan boy, he may need to disable the hot key F1 (if it's
possible in gnome2, as mr Havoc was so kind and thought the less configuration
options the less confused would the users be, so you can't do half of the
stuff you could do in Miguel de Icaza's Gnome).
