Re: scroll-conservatively default

    I have this since ages:

    (defun scroll-up-in-place (n)
      (interactive "p")
      (scroll-up n))

    (defun scroll-down-in-place (n)
      (interactive "p")
      (scroll-down n))

    (define-key global-map [(shift next)] 'scroll-up-in-place)
    (define-key global-map [(shift prior)] 'scroll-down-in-place)

Is this simply a way to scroll by one line with just one character?
