I need to keep track of the number of changes that have been applied to the
text in a TTEView. (Similar to the fChangeCount field of TDocument). My
first idea was to override the DoKeyCommand method to increment a field
within the view, but this won't work if the text was changed though cut and
paste.

I then thought of overriding the methods of TTECommand or its subclasses.
Before I spent too much time figuring out how these work (I've had a look
but am a little confused), can someone tell me whether I'm heading in the
right direction ? Larry, Keith, Kent, anyone ?

Thanks in advance.
