    That would be cool after I fix my emacs rustiness.

    Sure they would. I was thinking of Ctrl-N and Ctrl-S or something.

    An idea that I think would be useful is to mandate an escape character for
    all commands. After all, you might have variables named next and step. So
    how about "bang commands" when everything is prefixed by a "!". Then we'd
    have !next and !step, and perhaps shorter mnemonics Ctrl+letter.

    (and it's on by default)

    Yes, there should indeed be enough information given that the file and line
    are printed there. (BTW: lines /or filenames/ differ.)

    Thanks for the initial interest. I'll toy with a changed Whirlwind because
    the time I'll save is worth the effort.
