I have two machines. Both have a 3 button mouse, but one of them has a direction sensitive button rather than a mouse wheel, if that makes any sense. I have found from my experience making editors that it's pretty unusable (too sensitive). I don't think it is configurable, though can quite remember if I looked. (I don't have it here).
My solution was to use scroll wheel or arrow buttons
The setup you mention seems favourite assuming it's available and working ok.
