Comment 20 for bug 1228250

I think the change to help needs some work - it is just tagged on at the end
rather than being incorporated into the existing text. For example:

The line "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:"
probably needs to make reference to the fact the user's mouse might have
multiple wheels or one that the direction can be adjusted. I only have a
standard wheel mouse so I'm not sure if there is a standard place for these
extra features to be on an advanced wheel mouse - if there is one, maybe that
needs to be mentioned as it is for the standard wheel mouse.

Perhaps - "The Mouse Wheel preferences panel allows you to control how the
vertical mouse wheel (in between your mouse buttons) and the horizontal mouse
wheel (<location of wheel> - if you have one) on your mouse are used in Mozilla:"
