Comment 24 for bug 1228250

Great, thanks for the reviews! Those are all easily changed, although the
accesskeys still only work in the last tab (the one with shift), but from neil's
comment I understand that as a known problem.

The wording of the help text is much harder, before I post everything again as a
full patch, here is my suggestion:

   The Mouse Wheel preferences panel allows you to control how the mouse wheel
   on your mouse (in between your mouse buttons) is used in Mozilla.
   Modern mice may have two wheels or a button that can be used to switch the
   scroll direction of the wheel. The behaviour for the vertical wheel function
   is set in the upper panel <strong>Vertical scrolling</strong> while the
   horizontal mode is controlled by the lower panel <strong>Horizontal
   scrolling</strong>.

1st big item:
   [... in the small items add "characters" in brackets after lines
        and left/right after up/down ...]
2nd big item:
   If your mouse does not have a mode for horizontal scrolling, any setting
   in the lower panel <strong>Horizontal scrolling</strong> will be ignored.

One could add another item about mice with back/forward buttons but I think that
goes to far here, and I don't have a mouse like that so I can only guess from
bug 64485 what should be happening.
