[plt-scheme] Re: [plt-edu] world.ss ke=?

Thanks Danny and Shriram. Works like a charm! :-)

While on this, would it be a little simpler to treat all keystrokes as
either all chars xor all symbols? As it is now, the arrows are symbols
and the other keys are chars. Some of my (weaker) students seem
stressed over this and anything to make their life easier helps.

Cheers,

Marco
