That's not a very helpful response, since it doesn't address the OP's
Patrick, the operating system "interrupt current process" keyboard
signal will cause Python to raise a 'KeyboardInterrupt' exception,
which unless caught will propagate back to the top-level Python
process and exit the program with a traceback.
On most operating systems, you can send this signal to the current
foreground process with the key combination Ctrl+C. I think that's
what Benjamin's laconic response is implying.
As for "detect a specific keypress", there's no OS-independent way to
do that. You'll need to write code that depends on a particular way of
getting at keypresses that won't work on all operating systems.
