Trying to mirror my neovim setup in emacs I haven't found a way to make C-v and M-v scroll smoothly, i.e., line by line. Most solutions I looked at improve mouse and point scrolling, but not the before-mentioned shortcuts. Do I miss something?

  • There is scroll-up/down-line: they are not bound to keys, but you can do that yourself. Not sure whether they are what you are looking for however.

1 Answer 1


a way to make C-v and M-v scroll smoothly, i.e. one line at a time.

Maybe you can see 5.44 How can I force Emacs to scroll only one line when I move past the bottom of the screen?:

Customize the scroll-conservatively variable with M-x customize-variable RET scroll-conservatively RET and set it to a large value like, say, 10000. For an explanation of what this means, see Auto Scrolling in The GNU Emacs Manual.

Alternatively, use the following Lisp form in your .emacs:

(setq scroll-conservatively most-positive-fixnum)

It will change the behaviors of C-p and C-n. If you consist on changing the behaviors of C-v and M-v, bind the corresponding function (the function bound to C-p and the function bound to C-n) to M-v or C-v. (Not recommended, because C-v and M-v are there for you to move faster.)


Maybe you want this:

;; C-v
  ;; unbind `scroll-up-command` from `C-v`
  (global-unset-key [?\C-v])
  ;; bind the function you want to `C-v`
  (global-set-key [?\C-v]
    #'(lambda ()
        (let ((number-of-lines 15) ; scroll N lines
              (seconds/line 0.05)) ; spend N seconds scrolling one line
          ;; execute what you want:
          ;; “one line at a time”  
          (dotimes (_ number-of-lines)
            ;; Scroll up 1 line,
            ;; but the cursor moves on the screen too.
            ;; Move the cursor down 1 line so that
            ;; the cursor doesn't appear to have changed position.
            (sleep-for seconds/line))))))
;; M-v is similar
  (global-unset-key [?\M-v])
  (global-set-key [?\M-v]
    #'(lambda ()
        (let ((number-of-lines 15)
              (seconds/line 0.05))
          (dotimes (_ number-of-lines)
            (sleep-for seconds/line))))))
  • Seems like my wording has confused you. Scrolling with point near border can be made smoother, but I want C-v to have an animation instead of a sudden jump. Again, this kind of motion is what I'm aiming for. Commented Mar 2, 2023 at 11:26
  • @Trashbin2019np: The answer is updated; hope it helps you :-) I'll explain the details of the code at my leisure, but you can test it for yourself and see if it meets your needs.
