Unfortunately, on many OS's the user still would have to have pressed the Enter
key before keypresses are available to Get_Immediate. If your OS is one of
those, then you would have to make some sort of system call to get keypresses.

Most window managers come with a way to do this. Gtk is no exception. What you'd
want to do is set your application up to receive keypress events (GdkEvents of
type GdkEventKey). You could also probably do it with menu accelerator keys, but
that seems a bit cheesy. You can set button press and button release events for
any "Widget". If I'm remembering my Gtk+ properly, you'd probably want to set it
for your outermost-container, but its probably something that you'd have to play
with a bit.
