switch to repl buffer

[slipset]

In CIDER I can press C-c C-z to switch to reel-buffer when I'm in a source buffer, and when I'm in a repp-buffer and press C-c C-z, I switch back to the previous source buffer. From the Cider docs:

Switch to current REPL buffer, when possible in an existing window.
The type of the REPL is inferred from the mode of current buffer. With a
prefix arg SET-NAMESPACE sets the namespace in the REPL buffer to that of
the namespace in the Clojure source buffer
