What other applications define the selection using a point and mark? What
other applications extend the selection when you simply advance the cursor
(point)?

That would still be true for the idea I suggested. The region would not be
activated just by moving the cursor; that's all. That's similar to what
happens in other apps, AFAIK.

I did not say anything about the shifted arrow keys.

That was the idea.

The mouse is fine as is, I believe. I don't think anyone has complained
about it in this context.

Maybe my idea would have been better expressed as this: C-SPC would set the
mark but would not activate the region. That way, cursor movements
(including C-s) would extend the inactive region or the active region. In
the case of the active region, the highlighting (in t-m mode) would be
extended accordingly.
