Hi Tim,

Assuming a field I put in:

Clear
---
Choice 1
Choice 2
Choice 3
---
Choice 4
Choice 5
etc.

And in the script of the field:

on mouseDown
   local tHilitedLines
   -----
   lock screen
   put the hilitedLines of me into tHilitedLines
   if tHilitedLines = 1 then
     set the hilitedLines of me to empty
     -- clear
   else
     repeat with i = the number of items in tHilitedLines down to 1
       if line (item i of tHilitedLines) of me = "---" then
         delete item i of tHilitedLines
       end if
     end repeat
     set the hilitedLines of me to tHilitedLines
   end if
   unlock screen
end mouseDown

Hope this helps.
BTW if the above works, I'm not sure it's really compliant with usual  
guidelines on any platform ;-)

Best regards from Paris,
Eric Chatonet.
