By "place", I meant two things: (1) where the point is and (2) what is
the first (topmost) actually displayed (visible) line.

More or less. I'm now convinced that window configurations were what
I was looking for.

Right, it's not what I meant.

My goal (though probably not my words;-), sorry) is simple: I want the
"place" (in the sense of the above definition) to stay the same, /or/
I want to be able to easily restore it. The former should be doable
with narrowing, the latter probably with window configurations.

I heard about it, though I don't really see much use (for me, not in
general). OTOH, I use narrowing quite a lot, so maybe I could give it

I learned about it today while rereading the manual. Very useful

Well, now I see it...
But look at this:
,----[ (emacs) Configuration Registers ]
| You can save the window configuration of the selected frame in a
| register, or even the configuration of all windows in all frames, and
| restore the configuration later. *Note Windows::, for information about
| window configurations.
,----[ (emacs) Window Convenience ]
| Winner mode is a global minor mode that records the changes in the
| window configuration (i.e., how the frames are partitioned into
| windows), so that you can undo them.
See? Basically nothing in the /Emacs manual/ explains precisely what
a "window configuration" is. On the other hand, the /Elisp reference/
is pretty clear. I'd consider this a bug in the docs: a /user/ should
not need to consult the Elisp reference. I'll try to come up with
a patch for the docs soon.
