Right. So if you check the selectedChunk in a selectionChanged handler
you can tell the difference.

If it's just an insertion point you'll get something like
char 26 to 25 of field 1
and if it's a text selection (more than one char) you'll get
char 24 to 25 of field 1

Note that the first char selector is *greater* than the second if it's
just an insertion point.

on selectionChanged
  if word 2 of the selectedChunk > word 4 of the selectedChunk then
    put "this is ok."
  else
    put "I'm going to ignore the text chunk."
  end if
end selectionChanged
