I'm not great at naming symbols, so I don't insist.  However, the
original name seemed slightly misleading: it could be interpreted as
if the selection will be made backward, which is incorrect.  And since
I know that the "select-region" belongs to "mouse", I'm left wondering
what is "backward" about.

Do you see my problem with the name?  If so, perhaps you can suggest a
better one.

I don't think it's needed: since point doesn't move, no scrolling
should be expected.

Thanks.
