I'd argue that "export to WAV" is a special case because if you're going to
burn a CD, you need WAV files as source material. (I'm aware that other
formats could be coerced into being read by k3b or something, but that
would be extra work.)

Unless it's as good as I am, I don't want to use it. Like I said, I
only want to
do this job once. (Actually I want to do it zero times, but then I wouldn't be
able to listen to this music on "modern" equipment.)

Thanks for giving it a whirl. I really appreciate your time on this.
My code only sets the Export Directory if you give it a .wav file as an
argument, so it should only affect command line users.

This doesn't seem to work in Linux under KDE (i.e. Kubuntu). Alt-F pulls
down the file menu, but no keystroke that I tried would move the highlight
down off of "New". A working hot-key here would be priceless. Perhaps
the Fn keys (F1, F2, . . . F12) ?
