To avoid weird behaviour when seeing ends of your buffer, use the code
below.

(global-set-key [down] (lambda ()
			 (interactive)
			 (next-line 1)
			 (unless (eq (window-end) (point-max))
			   (scroll-up 1))))
(global-set-key [up] (lambda ()
		       (interactive)
		       (previous-line 1)
		       (unless (eq (window-start) (point-min))
			 (scroll-down 1))))
