I think I'd cheat a little and let the engine do it:

on getword
   put the selectedchunk into tSaveChunk
   get the topleft of fld 1
   put (item 1 of it + 10, item 2 of it + 10) into tStartLoc
   get the topright of fld 1
   put (item 1 of it - 10, item 2 of it + 10) into tEndLoc
   drag from tStartLoc to tEndLoc
   put the selectedText -- here's your text
   select tSaveChunk
end getword

You may need to adjust the click location if your margins aren't 
standard. You can also remove the part that saves and restores the 
current selection if the field is not editable. I didn't try it, but 
this may require that the field have its traversalOn set to true.
