* Universal/prefix argument for "other window" redirection?

Is there already a way to "automatically" modify interactive commands to
"auto-work" in other window instead of current window?

I know I can scroll other window already and switch to some buffer in
another window with `switch-to-buffer-another-window`, I already use
them.

What I would like is to have all the cursor motion stuff, expression
evals etc, work on in other window so I don't need to switch back and
forth two buffers (I like to work with two buffers side-by-side). I
wonder if there is already something I could use; prefix
command/universal prefix whatever, to autmoatically modify behaviour of
interactive commands involved or do I have to write my own (if it's
possible :))?

OT1H you mention universal-prefix (which only affects the very next
command) but OTOH you say "all the cursor motion stuff ...".

For the "all the cursor ..." case, it seems you're saying all the
commands should operate on the other window, which is exactly what you
get after `C-x o`, so your description needs more details to know what
you really mean.

I don't think there's already what you want.
Gregory's code is a workable starting point for the "just the next
command" case.  Another direction might be the `vcursor.el` approach.

ha! It was that simple :-). I had something else in mind, but good I
didn't wrote anything.

Seems to work very fine with some commands; not so good with others. For
example motion commands like forward char, word, line etc, seems to work
very good. C-x C-f does not work at all (for me it is
helm-find-files). I know there is C-x 4 C-f

I have put it on `§` as a shortcut and tested for a while today. I am
not sure if like my idea :). For "one-timers" quick commands it saves
switching to original buffer and feels overal lighter than switching to
other window and back. But some things felt slightly confusing since I
don't see the cursor, like evaling last expression. 

Cool anyway, thanks!

Haha, yes, I think I myself need more details to know what I mean :).

I don't know myself what I really want. I find myself switching a lot
between two windows, which sometimes feels redundant. Maybe it is just
the shortcut, C-x o, or in my case C-v o. After playing with Gregory's
example, I am thinking of just binding the other-window to the `§` key.
Maybe that itself will be enough for somewhat "smoother" experience.

Indeed, Gregory's code seems to be very nice tool for some quick
fixes. I'll take a look at vcursor.el too. Thanks.

Maybe what you want is a foot pedal that emits a ‘C-x o’ when pressed,
and another ‘C-x o’ when released. Something like vim-pedal[1] but for
Emacs.

[1]: https://github.com/foxweb/vim-pedal

Or an eye-tracking camera that focuses whichever window you are looking at.

(Me, I’m content with binding my local equivalent[^2] of s-[esdf] to
windmove-{up,left,down,right}-cycle.)

[^2]: It’s actually M-s-[frst] due to using the Colemak layout and
having two thumb modifier keys, one mapped to Super and the other to
Super+Alt. Super+[frst] switches i3 tiled windows and Super+Alt+[frst]
switches panes in whatever application is in focus — Emacs, Kitty
terminal, tmux if running in a single-paned Kitty tab.

Ha! I think we are onto something here. One of those el-piano pedals or
some old guitar effect pedal? A bluetooth wireless pedal? I mean a whole
board of those pedals, like guitar pedal boards. Imagine how many
modifiers we could have: ctrl, alt, hyper, super, duper ... maybe all on
just one pedal with tactile levels, and then add many pedals to it. I
think we have a product here :).

That is not a bad idea at all :). I am not sure how much eye-tracking
would this old laptop be able to process and what would happen when I
look elsewhere though. But maybe it is possible to make it smart enough?

> (Me, I’m content with binding my local equivalent[^2] of s-[esdf] to

I have also bound those, in my case C-v [lrud] for left right up and
down, but I think is as awkward as C-v o. Maybe I'll try vim shortcuts
for a while, but I see on Reddit people are switching from evil anyway.

Is there two thumb modifier for my hands? Feels I would need some.

That woudl be the ultimate keyaboard for Emacs indeed. Yes, the idea striked me
once, but I am not aware of any digital one. I don't think either I could
motivate to the best of all best wifes why my keyboard need a separate
room alone.

There is already C-x 4 4 but it doesn't work for every single case.

Indeed. I do use C-x 4 with some commands, C-x 4 C-f and C-x 4 b are some I
use sometimes. Unfortunately they move cursor over to other window too,
but I can wrap them in my own command.

I have tried vcursor now; haven't noticed it ever before. It is very
nice indeed. It complements C-x 4 functions and Gregory's approach. I
really liked the search in ohter window. That one solves a lot :-).

For the record, I had forgotten about it as well, but was reminded of it
a few days ago when I converted it to lexical-binding ;-)

I wrote a command that sends the cursor to another buffer window, and
lets you do whatever you want in that window, until you hit "q" (this is
a special-mode buffer so insertion isn't an issue), whereupon it pops
you back to the original window. It uses a transient keymap to do that,
which is yet another approach you could consider.

Interesting; thanks! Cool to see so many different ways to solve a
problem in Emacs. Thanks!

At this time I think I'll write a blog post as a summary instead of
bothering you all here.
