I was thinking that M-p would retain whatever mode we're in. So in that
example, we'd cycle only through symbol searches. Since there are
multiple different modes that combine combinatorially, maybe this is not
an ideal way to do it, but that's what I'm thinking now.

This conversation has been useful, and I'm now digging through
isearch.el to see what the quickest (and least intrusive) approach to a
patch would be.

Thanks
