Firstly, are you SURE you want arrow up/down to scroll the buffer? If
so, you won't be able to use these keys for moving the cursor, and will
need C-n and C-p for these purposes.
My solution is to have these function definitions in my .emacs:
*************************************************************************
(defun scrollup-n (&optional n)
"Scroll the text up n (default 1) lines."
(interactive "p")
(scroll-up (or n 1))
)
(global-set-key [S-down] 'scrollup-n)
(defun scrolldown-n (&optional n)
"Scroll the text down n (default 1) lines."
(interactive "p")
(scroll-down (or n 1))
)
(global-set-key [S-up] 'scrolldown-n)
(defun scrollup-6n (&optional n)
"Scroll the text up 6n (default 6) lines."
(interactive "p")
(scroll-up (* 6 (or n 1)))
)
(global-set-key [C-S-down] 'scrollup-6n)
(defun scrolldown-6n (&optional n)
"Scroll the text down 6n (default 6) lines."
(interactive "p")
(scroll-down (* 6 (or n 1)))
)
(global-set-key [C-S-up] 'scrolldown-6n)
*************************************************************************
As can be seen, I use SHIFT-up/down for scrolling by a single line, and
Control-shift-up/down for scrolling six lines at a time. You can modify
the global-set-key calls easily enough to take the SHIFT away.
