REPL Keybindings

Here's a list of the keybindings that are available in CIDER's REPL:

Keyboard shortcut Description
RET Evaluate the current input in Clojure if it is complete. If incomplete, open a new line and indent. If the current input is a blank string (containing only whitespace including newlines) then clear the input without evaluating and print a fresh prompt. If invoked with a prefix argument is given then the input is evaluated without checking for completeness.
C-RET Close any unmatched parenthesis and then evaluate the current input in Clojure.
C-j Open a new line and indent.
C-c C-o Remove the output of the previous evaluation from the REPL buffer. With a prefix argument it will clear the entire REPL buffer, leaving only a prompt.
C-c M-o Switch between the Clojure and ClojureScript REPLs for the current project.
C-c C-u Kill all text from the prompt to the current point.
C-c C-b
C-c C-c
Interrupt any pending evaluations.
Go to to previous/next input in history.
Search the previous/next item in history using the current input as search pattern. If M-p/M-n is typed two times in a row, the second invocation uses the same search pattern (even if the current input has changed).
Search forward/reverse through command history with regex.
C-c C-n
C-c C-p
Move between the current and previous prompts in the REPL buffer. Pressing RET on a line with old input copies that line to the newest prompt.
TAB Complete symbol at point.
C-c C-d d
C-c C-d C-d
Display doc string for the symbol at point. If invoked with a prefix argument, or no symbol is found at point, prompt for a symbol
C-c C-d j
C-c C-d C-j
Display JavaDoc (in your default browser) for the symbol at point. If invoked with a prefix argument, or no symbol is found at point, prompt for a symbol.
C-c C-d r
C-c C-d C-r
Lookup symbol in Grimoire.
C-c C-d a
C-c C-d C-a
Apropos search for functions/vars.
C-c C-d f
C-c C-d C-f
Apropos search for documentation.
C-c C-z Switch to the previous Clojure buffer. This complements C-c C-z used in cider-mode.
C-c M-i Inspect expression. Will act on expression at point if present.
C-c M-n Select a namespace and switch to it.
C-c C-. Jump to some namespace on the classpath.
C-c M-t v Toggle var tracing.
C-c M-t n Toggle namespace tracing.
C-c C-t t
C-c C-t C-t
Run test at point.
C-c C-t g
C-c C-t C-g
Re-run the last test you ran.
C-c C-t n
C-c C-t C-n
Run tests for current namespace.
C-c C-t l
C-c C-t C-l
Run tests for all loaded namespaces.
C-c C-t p
C-c C-t C-p
Run tests for all project namespaces. This loads the additional namespaces.
C-c C-t r
C-c C-t C-r
Re-run test failures/errors.
C-c C-t b
C-c C-t C-b
Show the test report buffer.
C-c C-q Quit the current nREPL connection. With a prefix argument it will quit all connections.


There's no need to memorize this list. In any REPL buffer you'll have a REPL menu available, which lists all the most important commands and their keybindings. You can also invoke C-h f RET cider-repl-mode to get a list of the keybindings for cider-repl-mode.

REPL Shortcuts

In the REPL you can also use "shortcut commands" by pressing , at the beginning of a REPL line. You'll be presented with a list of commands you can quickly run (like quitting, displaying some info, clearing the REPL, etc). The character used to trigger the shortcuts is configurable via cider-repl-shortcut-dispatch-char. Here's how you can change it to ;:

(setq cider-repl-shortcut-dispatch-char ?\;)
