gnu-emacs@gentoo.org Gentoo GNU Emacs project A Collection of Ridiculously Useful eXtensions for Emacs. crux bundles many useful interactive commands to enhance your overall Emacs experience. Most of the crux commands are related to the editing experience, but there are also a bunch of utility commands that are just very useful to have (e.g. crux-open-with and crux-reopen-as-root). Many of the functions in crux started life as blog posts on Emacs Redux, then were included in Emacs Prelude, before finally being extracted to crux. You can see a full list of blog posts on functions in crux on the tags page. https://github.com/bbatsov/crux/issues/ bbatsov/crux
