I'm new to the Emacs + Lein + nRepl + ClojureMode combination and seem to be at a loss as to why I cannot run the C-c C-, key combination in a clojure program buffer. It simply does not take the C-,. Other shortcuts, such as C-c C-k work just fine.
I'm using the Emacs from the Terminal OS X, on a Mac OS X Mountain Lion, if one might find that useful.
Thank you.
