Well for me the good news is at least I am not a total dunderhead who 
can't read documentation. Bad news is that it probably won't be fixed 
anytime soon, unlike problems with ESS.

I will give that a go. In ESS C-c C-n is normally bound to this function, 
correct?

My inexpert attempt at what to include in my .emacs to do this rebinding 
is:

(add-hook 'ess-mode-hook
   (lambda ()
     (local-set-key "\C-j" 'ess-eval-line-and-step)))

This seems to work. Any comments, suggestions?

Many thanks

David
