Thats much better than the original keys M-- M-r and C-n M-r
I change it a little like that we can do C-u n C-right or left

(defun screen-top (&optional n)
  "Move the point to the top of the screen."
  (interactive "p")
  (move-to-window-line (or n 0)))

(defun screen-bottom (&optional n)
  "Move the point to the bottom of the screen."
  (interactive "P")
  (move-to-window-line (- (prefix-numeric-value n))))
