using the left mousebutton in an unlocked field

[Lynch, Jonathan]

I just figured out that, while the mousedown handler does not work with
the left button in an unlocked field, one can do much the same thing
using the selectionchanged handler. I think this is very useful.

Like with the following script, which allows for regular left-button
hyperlinking in an unlocked field:

on selectionchanged
  if the linktext of the mousecharchunk <> empty then
    put the linktext of the mousecharchunk into LT
    if exists(card LT) = true then 
      go card LT
      unlock cursor
    end if
  end if
end selectionchanged

on mousemove
  if the mousecharchunk <> empty and the linktext of the mousecharchunk
<> empty then
    set the cursor to hand
    lock cursor
  else
    unlock cursor
  end if
end mousemove
