Another way is to add a new argument WINDOW to all commands. Then the interactive form could send the window value to the body. But when an interactive selection of a window by the user is not involved, then you can just call the same function like 'other-window-for-scrolling' twice: in the interactive form and in the body it should return the same. > I have both in my WM and in Emacs that focus should follow mouse.
