size-indication-mode, but it's not as immediately obvious as the scroll bar.
But recently, I discovered Lennart Borgman's
sml-modeline, which combines all of the scroll bar information into a nice visual indication on the modeline, and I have been happily using it, and got rid of my scroll bar.
load-path, and the following fragment in your
.emacsshould do the trick:
(if (require 'sml-modeline nil 'noerror) ;; use sml-modeline if available (progn (sml-modeline-mode 1) ;; show buffer pos in the mode line (scroll-bar-mode -1)) ;; turn off the scrollbar (scroll-bar-mode 1) ;; otherwise, show a scrollbar... (set-scroll-bar-mode 'right)) ;; ... on the right
Note, there is a older version available in Emacswiki which has some problems (such as conflicting with the Standard ML editing mode for emacs); thus, for now it's better to us the Launchpad version; the instructions above apply to that version.
