centered-cursor-mode.el

Makes the cursor stay vertically in a defined position (usually centered) while scrolling. So instead of moving the cursor up and down it moves the page like a pager.

The vertical position can be customized.

The code is still in development (see todo list).

Also see the development branch https://github.com/andre-r/centered-cursor-mode.el/tree/dev which contains several changes. It is faster and has better customization. But it lacks one feature for now: because of performance issues, at the end of the buffer the cursor it is still recentered, so that the text does not align with the end of the window.

Usage

To install using use-package:

(use-package centered-cursor-mode
  :demand
  :config
  ;; Optional, enables centered-cursor-mode in all buffers.
  (global-centered-cursor-mode))

You can activate in a single buffer:

M-x centered-cursor-mode

or enable globally:

M-x global-centered-cursor-mode

Customizable variables begin with ccm-.

Technical

If recentering is triggered after some sort of mouse interaction and you don’t expect it to, this might indicate an incompatibility with some other mode you are using. A quick way to figure out what commands are actually triggered when you interact with the mouse is to use command-log-mode which will show you a stream of the command history as the commands are being evaluated.

If any of the commands triggered on mouse interaction is not included in ccm-ignored-commands, you have found the cause.
