[ESS] Help configuring auto-complete

[Ista Zahn]

Hi all,

Sorry for resurrecting this old thread. I just wanted to note for
future googlers that I finally solved this problem to my complete
satisfaction using

(define-key ac-completing-map "\t" 'ac-complete)
(define-key ac-completing-map "\r" nil)

I had tried this before without succes, but it now works as intended
(not sure what the problem was before)

This prevents auto-complete from completing when the return key is
pressed, and instead uses the tab key for this. Although I don't think
I realized it myself when I first opened this thread, that is actually
what I want, and I'm now very happy with the way auto-complete is
working with ESS.

Thanks again,
Ista
