Ehum, yes, if you use Viper at least... ;-)

It is actually very good if you know vi.

Otherwise try the command move-to-window-line.

You can easily define these two commands:

(defun move-to-window-first-line ()
  (interactive)
  (move-to-window-line 0))

(defun move-to-window-last-line ()
  (interactive)
  (move-to-window-line -1))

... then bind them to what you want.

I only recently found this, even though it is prominently bound to M-r.
The command is `move-to-window-line', which moves to the middle.

For top, bottom:

(defun move-to-top ()
  (interactive)
  (move-to-window-line 0))

(defun move-to-bottom ()
  (interactive)
  (move-to-window-line -1))

;;    M-r  =  move-to-window   (by itself its 'M' in vi)
(global-set-key "\C-x\M-r" 'move-to-window-first-line)

So these are already bound to keys

C-U 0 M-r     move to first line
C-U - 1 M-r   move to first line

When in X these can be shortened to

M-0 M-r
M-- 1 M-r    that one is meta minus, followed by 1, followed by meta r

The latter can be shorter:

M-- M-r

Hi,

{catching up on my mail log}

I did not see this answer so in case it could help:

in window.el, you have recenter-top-bottom function which is
bound to just C-l.

It will cycle between top, bottom and center of the screen. It is
so convenient and I got so used to it that I could not pass over
me ;)

Not in the window.el distributed with Emacs 22.3

FYI - The code runs in previous Emacs versions also.

The original is here, along with a couple of alternatives:
http://www.emacswiki.org/emacs/misc-cmds.el

And the CVS version is here:
http://cvs.savannah.gnu.org/viewvc/emacs/emacs/lisp/window.el?view=log

This behavior is also the new default in emacs 23.
