I have this minor mode set to work on all buffers:

;; John Mercouris centered point mode
;; Homepage: https://github.com/jmercouris/emacs-centered-point

(define-minor-mode centered-point-mode
  "Alaways center the cursor in the middle of the screen."
  :lighter "..."
  (cond (centered-point-mode (add-hook 'post-command-hook 'line-change))
    (t (remove-hook 'post-command-hook 'line-change))))

(defun line-change ()
  (when (eq (get-buffer-window)

(provide 'centeredpoint)

(centered-point-mode t)

This is close to what I want. I wished this was a global mode working on all buffers, except for the SLIME's REPL buffer.

How can I insert this exception in my config files?

What should I change on:

(centered-point-mode t)

    Does this answer your question? Disabling visual-line-mode only in org-agenda-mode

  • I do not use @drew Slime anymore... It has been 6 months. I am not sure. But, I think no. It would not answer the question as the answer below did. Dec 2, 2022 at 18:37

    This is an older question of which this one is essentially a duplicate. This is what I should have pointed to (the question really has nothing to do with any particular major or minor modes): emacs.stackexchange.com/questions/50339/…

1 Answer 1


Something like

(add-hook 'slime-repl-mode-hook (lambda () (centered-point-mode -1)))

which toggles the mode off in slime REPLs.
