To scroll pages by MS 4000 Keyboard's Zoom in Firefox without MS's drivers

Question

I would like to change MS 4000 Keyboard's Zoom to Scrolling pages in Firefox without the use of MS's drivers which causes only problems in OS X.

How can you change MS 4000 Keyboard's Zoom to Scrolling pages up and down in Firefox?

Answer 1

I can't find anything about zooming in about:config, so you may be out of luck.
