Hi all,

I would like to keep my cursor always in the middle of the screen,
even if I'm writing at the bottom of a buffer.
I added the following snippet to my init.el


    (use-package centered-cursor-mode
      :ensure t
      :init
      (global-centered-cursor-mode 1)
      )
    (setq scroll-margin 28) ;; full screen = 57 lines
    (setq-default indicate-empty-lines t)

but it doesn't work and the cursor is only around 25% of the buffer.
see here : https://imgur.com/3glkqEa.png

(also I assume I should set a hook because I don't want to loose 50%
of screen space for terminal type buffers)

Thanks,

`C-l`?

`centered-cursor-mode` does that automatically.

And as `centered-cursor-mode` , `C-l` doesn't center at the bottom of
a buffer.

> C-l?

It is bound to recenter-top-bottom, which as the names says, moves the
buffer and the cursor to top, bottom and center (in that order).

But one can :

    (define-key global-map (kbd "C-l") #'recenter)

to make the cursor to only recenter the buffer. However, it is not the
same as always keeping the cursor in the center. For that, I think one
has to do some scrolling of the buffer instead of moving the cursor,
if it is even possible to *always* keep the cursor in the center.

Have you looked into setting `ccm-recenter-at-end-of-file` to `t`?
