Re: split screen horizontally into three equally spaced sections

Hello,

First thanks to Harven and Lennart for their answers, and to
you, Bastien, as well...

FYI, I've tried the transpose window stuff from EmacsWiki, and
it perfectly works...

Thanks for the example. It wasn't that clear for me, even after
looking through winresize.el.

Of course, you have the ediffing case where I want to easily
switch from one configuration to the other, depending on what
I'm comparing and how (having my Emacs full screen or not). But
there is already a key binding for that.

Another case is, for example, when I'm reading mail. Sometimes
I'd like to pass from the first screen configuration above
(which is my default one, with Gnus) to the second, in a matter
of seconds, and without the mouse).

In that case, I first force full screen (under Ubuntu) with `C-c z':

--8<---------------cut here---------------start------------->8---
(unless running-ms-windows
    (defun my-toggle-full-screen ()
      "Toggle between full screen and partial screen display on X11;
    courtesy of http://www.emacswiki.org/cgi-bin/wiki/FullScreen"
      (interactive)
      (x-send-client-message nil 0 nil "_NET_WM_STATE" 32
                             '(2 "_NET_WM_STATE_FULLSCREEN" 0)))

    (global-set-key [(control c) (z)] 'my-toggle-full-screen))
--8<---------------cut here---------------end--------------->8---

and then I have to switch the split of the windows, which was
the missing piece of my puzzle.

Does this make sense?

Best regards,
  Seb
