I still think you don't.

Indeed, that's what it's about.

It's not bound to anything in global-map, AFAIK.

That's the current (new) state in emacs-23 (not yet propagated to trunk).

Never heard of `iso-tab' (we have `iso-lefttab', tho, so maybe that's
a hint that there's an `iso-tab' somewhere as well).  Is that event
found under W32, or X11, or when?
