Hmm, it doesn't appear to work at all unless menu_complete is set :(
'fg <tab>' yields 'fg %' and no number of tabs causes it to complete anything,
which is unfortunate, as I don't like menu_complete personally - I prefer
to have completion complete as far as is unambiguous, auto-list the completions
and then do menu completion if <tab> is pressed after that. I think the
options that I use to do this are autolist and list_ambiguous ( but not
menu_complete).

I'd love to not use a temp file, but it appears that piping 'jobs' output
through anything results in the RHS of the pipe getting nothing whatsoever (ie.
'jobs | cat' produces nothing at all, 'jobs | echo' produces just a newline).
It'd be nice if there was another way to do this - I also have the somewhat
silly:
precmd() {
jobs > /tmp/.zsh_jobs.$$
psvar=$(wc -l < /tmp/.zsh_jobs.$$ | tr -d ' ')
}
PS1='%%%1v:%~%#'
to get the number of jobs in my prompt.

True, dunno why I had that in there :)

Ah, most excellent! I'll have to tweak a few other compctls I have to
use that (and read up on that construct in the man page:)

Naturally. That was my intention once I got it working the way I wanted
it.

Thanks very much! Now if I can only get it to work without having
menu_complete set, I'll be one happier camper ;-)
Thanks,
