These are the "keys" associated with the mouse wheel. In case you want
to scroll with the mouse wheel.

I dunno how you want to scroll. Drag with mouse-1, scroll with a wheel
or a key, something else?
The code
#+begin_src emacs-lisp
(defvar ml-scroll-amnt 0)
(setq-default
mode-line-format
`(:eval (substring (format-mode-line ',mode-line-format)
ml-scroll-amnt)))
#+end_src
has to be evaluated once. Mode-line looks like before.
(setq ml-scroll-amnt 3) scrolls the mode-line three chars to the left.
(setq ml-scroll-amnt 0) to scroll back. Changing `ml-scroll-amnt'
changes the scroll amount.
How you implement changing the binding of `ml-scroll-amnt' is up to you,
depends on how you want it to be.
Scrolling to the right would only prepend space to the beginning, so I
didn't handle negative `ml-scroll-amnt' values.
Michael.
