FWIW, I agree that handle-evt is more generally useful than wrap-evt (programming with breaks gets tricky and would require it's own setup).
You can use things like @interaction[] to run and typeset examples; does that help? http://docs.racket-lang.org/scribble/eval.html?q=interaction#%28form._%28%28lib._scribble%2Feval..rkt%29._interaction%29%29 Robby On Mon, Oct 7, 2013 at 10:33 PM, David T.
