mouse to move the cursor?

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

    This might sound outright heretical and it
      probably is, still ... would it be possible to be able to use the
      mouse to position the cursor within a command line?  Since most
      everything is now mouse-capable, out of habit I often find myself
      clicking on a recalled zsh command line to position the cursor. 
      Of course it doesn't work, but *could* it work?  I'd expect it to
      be viewed as a silly luxury even if it was doable, but I'll
      mention the idea anyway.  If that kind of thinking was acceptable
      one might even contemplate various other mousey things, like maybe
      the scroll wheel activating command recall or being able to
      dedicate left and right clicks to assigned widgets or commands ...
      could get interesting.
