Thanks, I missed such a command for a long time.
And 'remote-control-other-window' is an exact name.

It does no harm when the command is redirected to the same single window.

Windmove.el looks like the most suitable place since it also
provides quick keys for customization.  The same way you can choose
a key to use another window, like there are already similar keys
to scroll another window with M-<next>/C-M-v and M-<prior>/C-M-S-v,
etc.
