I'd really like something like that -- I'll often be using repeated C-c
C-n and accidently hit one on the end of the chunk and end up in
TeX-normal mode due to AUCTeX, requiring a save and revert.
Functionality like (M-n c M-x ess-eval-chunk) bound to a key would be
great.  But with my elisp skills, I can't quite make this work:

(defun ess-eval-chunk-and-step (vis)
  "Tangle the current chunk, send to the ESS process, and move on
to the next chunk.

Arg has same meaning as for `ess-eval-region'."
  (interactive "P")
  (ess-eval-chunk vis)
