Ah!! Apparently I was only testing bound keys, ctrl-s, ctrl-d, etc, and 
I thought ctrl-b wasn't bound because it didn't do anything apparent on 
the first try. But pressing ctrl-2 produces the behavior I want.

So Robby, is there a way to unbind all ctrl-# keys in drscheme so that I 
can get them in the editor-canvas?
