Highlighting can't easily be done for the region in EMACS. Remember, though,
that marks in EMACS are different from marks in Zwei. In EMACS, there is
a stack of marks. In Zwei, there is one mark and a stack of points.
There is always a current region in EMACS, but not always one in Zwei. So
if someone did modify the redisplay routine in TECO (written in PDP-10
code) there would almost always be some reverse-video portion of the
screen.
You can use the TMACS library M-X Graph Buffer command to get a graph
of what the buffer looks like. Do M-X Load Library$TMACS first.
You can also use ^X-^X to exchange the point and the mark just before
you do M-W or such operations. It will show you clearly what the
region is.
