​The main question I am trying to address is how to tell an Elisp programmer
how to redirect user input to an arbitrary window.  Whether or not we have
a specific name for this redirection, where user input goes changes when
select-window is called within the selected frame.  So there is input focus
which is frame-related but there is also window-related input redirection.
My argument is that there needs to be one place to look to understand
that.

Maybe select-window is not the place, it just seems that programmers
focused on
handling windows would naturally look there.

How and where would you explain this?  Can you explain how to do it in a few
sentences?  If yes, then let's add it somewhere and make it easy to find.
If not, then maybe a simplifying function would be justified.

I read through parts of the Elisp manual.  The section on Windows does not
explain
how to redirect user input ot an arbitrary window.  The top-level on Frames
does
not either.  It is not until I get to the section on Input Focus that I get
any
helpful information on this and that section refers only to frames, not
selected
windows.

So my thought is that where interactive user input goes is broader than
input focus,
is connected to what window is selected, and should be explained in one
place in
a succinct manner that is easily findable when looking up windows or frames.
