On MouseWithin -- UNSOM technique by Guy Kuo, December 13, 1987
  -- If the the option key is depressed, set the cursor to indicate
  -- we are in a special mode.  While the option key continues to be
  -- depressed, and the mouse is within the target field, wait for
  -- mouseDowns.  If one occurs, Pick up the word by clicking at the
  -- last MouseLoc twice and getting the selection.
  -- If the selection is not empty, do something with it.  In this demo,
  -- we put it into another field.  Finally, click outside of the field
  -- to avoid looping.  Hopefully, (-1,-1) is outside of all active
  -- objects.
  --
  -- While editing such a field, entry of Optioned characters from
  -- the keyboard no longer requires movement of the mouse outside of
  -- the field.  However, the optioned characters do not appear until
  -- after the option key is released

  if the OptionKey is down then
    if the locktext of the target is true then
      put true into DidUnlock
      set locktext of target to false
    else
      put false into DidUnlock
    end if
    set the cursor to 2
    repeat while (the OptionKey is down) and (item 1 of the rect of target <= item 1 of the mouseLoc) and (item 1 of the mouseLoc <= item 3 of the rect of target) and (item 2 of the rect of target <= item 2 of the mouseLoc) and (item 2 of the mouseLoc <= item 4 of the rect of target)
      if the Mouse is down then
        click at the MouseLoc
        click at the ClickLoc
        if the selection <> empty then
          put the selection into card field "result"
