See this post to ess-help from Martin Maechler:

It contains an entry to add to your .emacs file. To bind the history-search commands to <control>+<up/down>, I changed the key binding lines as follows:

(eval-after-load
    "comint"
  '(progn
     (setq comint-scroll-to-bottom-on-output 'others) ; not current
     ;;=default: (setq comint-scroll-to-bottom-on-input nil)
     (setq comint-scroll-show-maximum-output t) ;;; this is the key
     (define-key comint-mode-map [C-up]
       'comint-previous-matching-input-from-input)
     (define-key comint-mode-map [C-down]
       'comint-next-matching-input-from-input)
     
     (define-key comint-mode-map "\C-a" 'comint-bol)))


Boa sorte!
