The incredibly handy Clojure Cheatsheet, updated for Clojure 1.5 and packaged into an easy, fast, searchable, offline form:

If you’re hooked up to MELPA:

M-x package-refresh-contents
M-x package-install RET clojure-cheatsheet

Alternatively just grab the single clojure-cheatsheet.el file and install that in your preferred way.

Call M-x clojure-cheatsheet and the cheatsheet will appear. Type in some terms (space separated) to narrow down the list. For example, try typing in sort map to some functions that deal with sorting maps.

This package stands on top of Helm. The variable helm-source-clojure-cheatsheet is available if you want to mix it in as a Helm source.

Ready to use. Based on Clojure 1.5.1. Feedback welcomed.
