I would like to be able to have

  • a C-x 3 split to have two windows in a frame
  • both windows view a single buffer
  • window on left ends at line n
  • window on right starts at line n +/- configurable offset
  • vertical scrolling action scrolls BOTH windows

Does something like this already exist?

    I think what you are asking for is different enough from this that it's not a duplicate, but you should look at this, it might be good enough for you purposes, it doesn't do the n-line configuration you're taking about, but you can use it to open a file in two windows, use jump down a page in one buffer, enable this mode and then you have what you want I think. emacs.stackexchange.com/questions/288/… Commented Jan 7, 2020 at 19:34
  • Thanks Jordon - I found follow-mode (which handles displaying a single buffer in multiple windows) from following your suggestion. Your link suggest scroll-all-mode which allows linked scrolling of different buffers.

The closest existing tool to what I have asked for is follow-mode:


  • M-x follow-mode to trigger manually
  • (setq follow-auto t) to trigger automatically
  • C-c . 1 or M-x follow-delete-other-windows-and-split to maximise the current buffer in a two column format
