"Window" in Emacs terminology: the pane you are looking through to see
the content of the buffer. A "frame" can contain several windows. Concerning
your wish, it doesn't make much difference, because the relations between
window and frame don't change while scrolling (I'd hope ;-)

Yes, that's why I pointed it out as soon as I noticed. I don't have
a direct solution to your problem (but there's another answer which
looks good), but I thought I could help bridging the sematic gap.

:-)

But actually, this is one of the difficulties in getting up to speed with
Emacs: it's a toolset with a long history, and thus with a rich and
deeply ingrained culture which, to beginners poses a hurdle. Sometimes
things "you know" are called in strange ways, sometimes "you do" things
differently. Of course, you can customize (nearly) everything to your
liking, but sometimes it's difficult to express what you want in a
way that the Emacs tribe understands it.
