Magnar Sveen has Episode 10 of Emacs Rocks! up. This time he demonstrates ace-jump-mode and ido-imenu. Both of these provide fast ways of moving around in an Emacs buffer. They’re really quite impressive as you’ll see when you watch the video.
Ace-jump-mode is available on Marmalade with ELPA or from github. Imenu is part of Emacs but the integration with ido requires a bit of additional code. Georg Brandl has a package, idomenu, on EmacsWiki to do that. It looks as if that’s what Sveen used. There is also some code on EmacsWiki that you can add to your .emacs or init.el file to do the same thing. That code includes pushing the mark so you won’t have to add it as Sveen did.
As usual, this episode is entertaining and full of great information. You should definitely watch it as soon as you can—it’s only 2 minutes, 8 seconds long.
