By the way, are people aware that you can trap control keys with the hack
(either version). At least for me, Control+a-z map to keys 1B-26B. C-p for
print anyone? Haven't tried this one on anything but Unix. Just in case people
couldn't find the post I've reattached the latest hack with this modification.
Just run tt and try various keys, including control+letter and arrows. If
people want to experiment along these lines on other platforms/os's, I'd be
willing to collect the results and bundle the routine into something generically
useable and distributeable. Maybe then RSI would take notice and work to
include a less hackish alternative.
