How do I fix the cursor to the middle of the screen in Emacs, so that the page moves, not the cursor?

问题

I'd like to fix the cursor to the centre line of the screen, so that when I press Ctrl-N or Ctrl-P, the page itself moves up or down, and the cursor stays still.

Has anyone got any tips on how to achieve this?

Thanks

Ed

Try centered-cursor mode:

If you're using MELPA, it's available by M-x package-install RET centered-cursor-mode.

M-x scroll-lock-mode, which could be used to put the Scroll Lock key to good use too:

(global-set-key (kbd "<Scroll_Lock>") 'scroll-lock-mode)

The EmacsWiki page on SmoothScrolling presents some possible solutions.

You can roll your own using the recenter built-in:

(global-set-key (kbd "C-n")
        (lambda (n)
          (interactive "p")
          (next-line n)
          (recenter)))

(global-set-key (kbd "C-p")
        (lambda (n)
          (interactive "p")
          (previous-line n)
          (recenter)))
