My 3000D is waiting a CPU, once I get it all going again (a few weeks or so) I will test out CSH and see what it can do.
It was my favorite shell back in the day. The shortcuts saved a ton of typing and the type complete was the best imho. Remember it by default used custom colors when you turned it on. Not sure how many pens you can set, it might be buried in the docs somewhere.
Good luck!
