Source Code

;; Defined in /usr/src/emacs/lisp/follow.el.gz
;; This function is added to `pre-redisplay-function' and is thus called
;; before each redisplay operation.  It supersedes (2018-09) the
;; former use of the post command hook, and now does the right thing
;; when a program calls `redisplay' or `sit-for'.
