Hi, Drew!

Mine doesn't seem to mind at all.  But I know some do.

Please don't.  These two keys are already used in Isearch Mode for
scrolling.  To see this, set `isearch-allow-scroll' to t.  Then <next>
and <prior> are handy keys for seeing more text around the match without
having to leave isearch and start again.

The same applies to any keys bound to commands which have the
`isearch-scroll' non-nil.

I can't think of any more suitable keys for this - maybe keypad-+/-, or
keypad-del/enter, but they're probably not reliably on all keyboards.
Sorry to be so negative.
