	This is happening because `C-v' with no argument takes the las two
lines at the bottom of the buffer (or as many as the variable
`next-screen-context-lines' tells it to) and puts them at the top. If this
command (scroll-up) receives a numeric argument (M-n or C-u n) scroll text
upward `n' lines... some other commands work like this too.

	I don't know if there is such a command. Actually, I don't think
so!, but, hey we can make one :)

(defun scroll-n-windows (n)
  (interactive "p")
  (when n
    (scroll-up (* (window-height) n)))
  (scroll-up))

just make the appropriate binding (i.e. to C-v), but I don't find it useful
at all, I mean if I want to move so many lines, then I'd rather use: M-n C-n.

Anyway... cheers,
Francisco

The documentation for scroll-up and scroll-down clearly state that
the argument is the number of lines.  If no argument, then it is a
single screen.  Fortunatly, Emacs provides an easy way to enter a big
number without resorting to typing in the number itself.  The `universal
argument', C-u, corresponds to a power of 4 for functions wanting a
numeric argument.

So, if you just want to jump down by 256 lines, do this by:
C-u C-u C-u C-u C-v
