Emacs: how to trigger scroll when cursor is n-lines from top/bottom of screen?

Question

I'd like to trigger a scroll in emacs when my cursor gets within 4 lines from the top or bottom of the terminal.

My .vimrc file contains this line:

:set scrolloff=4

What do I add to .emacs to acheive the same?

PS. I promise not to add it with:

vi ~/.emacs

Answer 1

I think scroll-margin will help -- look for it in the Emacs docs on Textual Scrolling.

Put this in your .emacs:

(setq scroll-margin 4)
