Each Emacs window displays one Emacs buffer at any time. A single
buffer may appear in more than one window; if it does, any changes in
-its text are displayed in all the windows where it appears. But the
-windows showing the same buffer can show different parts of it, because
-each window has its own value of point.

has a location of point as well. On text-only terminals, there is no
