There are 2 methods suggested in the 1st and only issue of Windoid, Apple's
Hypercard User Group's informal publication (it was posted here a couple of 
weeks ago).

Method #1: Place a tansparent button over the word in question, or an 
           asterisk button after it. This has the advantage of not being
           ambiguous, but it is not flexible (i.e. the button doesn't move
           with the text, as in a scrolling field).

Method #2: Place this script within your field handler:

on MouseDown
  Set locktext of me to false
  click at the clickloc
  click at the clickloc
  if the selection is "Apple" then
    answer "What kind of Apple" with "Macintosh" or "Apple II"
  else
    put "I don't know that word" into msg
  end if
  set locktext of me to true
end MouseDown

          Of course, the disadvantages of this method are paramount, also. If
          you have a locked scrolling field, you may be able to do something
          with double-clicking on the word within the script (like above) and
          then finding its offset into the field. If it is in the right 
          position, then do what you need.


It says in the introduction of Danny Goodman's book that Bill Atkinson is
dedicated to the evolution of HyperCard for the next several years. If this is
the case, then be sure to make your request enhancements known.
