|

;; * Press <\\[describe-mode]> to see a list of the keybindings available (this

|
||
;; * Press <\\[cider-repl-handle-shortcut]> to quickly invoke some REPL command
|

;; * Press <\\[cider-switch-to-last-clojure-buffer]> to switch between the REPL and a Clojure file
|
||
;; * Press <\\[cider-find-var]> to jump to the source of something (e.g. a var, a
|
||
;; Java method)
|
||
;; * Press <\\[cider-doc]> to view the documentation for something (e.g.
|
||
;; a var, a Java method)
|
||
;; * Enable `eldoc-mode' to display function & method signatures in the minibuffer.
|
||
;; * Print CIDER's refcard and keep it close to your keyboard.
|
||
;;
|
||
;; CIDER is super customizable - try <M-x customize-group cider> to
