Hi,
this is done with scroll-other-window.

,----[ C-h f scroll-other-window RET ]

from my .emacs.el :

(defun scroll-other-window-up ()
  "Scroll the other window one line up."
  (interactive)
  (scroll-other-window -1)
)
(defun scroll-other-window-down ()
  "Scroll the other window one line down."
  (interactive)
  (scroll-other-window 1)
)
(global-set-key [C-M-S-up] 'scroll-other-window-up)
(global-set-key [C-M-S-down] 'scroll-other-window-down)

Add Shift key to that key combination.

    C-M-S-v runs the command scroll-other-window-down, which is an
    interactive compiled Lisp function in `simple.el'.

    It is bound to <M-prior>, C-M-S-v, ESC <prior>.

    (scroll-other-window-down LINES)

    Scroll the "other window" down.
    For more details, see the documentation for `scroll-other-window'.

So a negative prefix is all you need.

Re: How to scroll other window backwards? C-M-v does forwards

Hi,

I must be confused.  I want to scroll the other window both up and
down.  I can scroll the other window down, but not up.

control + meta + v scrolls the other window down.
control + meta + shift + v does not scroll the other window up, as
someone suggested.

Could someone tell me if it's possible to scroll the other window up?

Thanks!

Yes, it's possible.

Try, for example, "C-u -40 C-M-v".

Does that help?
