Here are my defined functions:

(defun middle-window () "go to line in middle of window" 
       (interactive)
       (move-to-window-line (+ (/ (1- (window-height)) 2))))

(defun line-to-top (arg) "move current line to top of window"
       (interactive "p")
       (recenter (1- arg))
       (middle-window))

(defun line-to-bottom (arg) "move current line to bottom of window"
       (interactive "p")
       (recenter (- (window-height) (1+ arg)))
       (middle-window))

Please note that these functions will put the cursor at the middle of
window after moving the text. If you do not want that remove the
"(middle-window)" [ leave 1 ")" ].

I assign the keys Shift-Page-Up and Shift-Page-Down to these commands:

(define-key global-map '[S-next]     'line-to-top)    ;shift pg-dn key
(define-key global-map '[S-kp-next]  'line-to-top)    ;shift pg-dn key (keypad)

(define-key global-map '[S-prior]    'line-to-bottom) ;shift pg-up key
(define-key global-map '[S-kp-prior] 'line-to-bottom) ;shift pg-up key (keypad)

Ehud.
