   See my reply to Stefan.  And please try some more clicks with
   "What's This?" to see that what it does is not really answer the

   very close to what our describe-key does.

I believe there is some confusion here.  One of the reasons why the
KDE (and I presume MS Windows) version of "What's this?" is very
different from `describe-key' is _because_ it answers the question
"What's This For?" if you click on something.  If you click mouse-1 on
the minibuffer or fringe, the KDE user (and Lennart claimed the
Microsoft user too) would expect a tooltip telling what the
minibuffer/echo area or fringe are for.  But `describe-key' tells you
what command mouse-1 is bound to at that particular place and gives
you some Elisp documentation about that command.  These are two very
different things.

Sincerely,

Luc.
