Well, arrow keys, for one; TE does handle them all by itself.

It would be convenient if TE did tell you if it changed text, or only
the position of the insertion point.  It isn't impossible the way you
suggest (I do it myself), but it _is_ messy and it _would_ be nice if TE
could tell you, since it knows.  Perhaps something like ScrapCount could
work.

Of course, it would be even nicer if TE handled text >32K, but I guess
Apple feels that's a wheel we should all invent separately.
