Yeah. When picking the keys for Dunjunz (which had to not conflict
between two keyboard players and still work with joystick players
pressing their firebuttons), I had to knock up a noddy Perl script to
test various choices.
Even then I very much depend on the idea that people are unlikely to
be pressing Up and Down at the same time - else it might not have been
possible!
