Might work to do it the traditional Ruby way:

http://betterlogic.com/ro...

windows:
trap :INT, proc { â??ha got your ctrl-c!â?? }

and linux

trap â?SIGUSR1â?³, proc {â??got it in linux, tooâ??}

I think. Maybe add to environment.rb?

As I see it: he doesn't want the user to copy text.

Not the answer you might expect: don't even try. You showed him the =20
text. If he is serious, he will use the old analog method of copying.

That would stop the Rails application from processing a ctrl-c on the =20=

server keyboard (if it has one) but would make no difference in the =20
browser as the Ruby code doesn't run there.
