iedit for Emacs
Just added a new package to the AUR for iedit, which is a pretty cool mode for Emacs to edit in place a bunch of regions containing the same text. See this post by Mastering Emacs for some usage and a nice little defun to narrow the changes to the current defun:

Nice!
Just yesterday a friend told me about this awesome mode he found at EmacsRocks.com, nice to have it here
BTW, thanks for the pointer on EmacsRocks.com – what a wonderful set of videos! Been using Emacs for 20+ years and still learning new things.
It looks cool, but now I just have to remember to use it, instead of replace-all!
