Well if you click instead of using the arrow keys, I think you'll find that
the field boundaries and XML node markers are actually considered one
character each so far as the selection index goes (as long as you have them
shown).  Just play around with the event a little, you'll find that the
character just in front of the XML node sometimes comes up as x, and other
times as y, depending on how you got the selection cursor there.  Cursoring
back over the node yields a different result than cursoring to the node or
clicking with the mouse.

So I think my question is still...in question.
