The 'browse origin' search does not seem to find it (maybe I'm using it wrong?).

But the method originally entered Squeak here:

  Name: Morphic-ar.149
  Author: ar
  Time: 6 August 2009, 4:23:12 am
  UUID: fc14d160-97da-6142-8002-827d24037a57
  Ancestors: Morphic-jmv.148
  Integrate Cuis text editors. The new classes are Editor and TextEditor
  (in Morphic-Text Support). TextMorph now honors the preference
  #userNewEditors to determine whether to use the (old) TextMorphEditor
  or the (new) TextEditor (shameless plug: pragma preferences rock; check
  out TextMorph class>>useNewEditors).  There is still a ways to go before
  this will work but it gives us the starting point to knock down the
  remaining issues with the editors (mostly keyboard shortcut issues).

If you look at senders of selectInvisiblyFrom:to: in Squeak, there are
several cases where the sender subtracts 1 from the stop index before
sending. There are no such cases in Cuis.
