Mighty Mouse scroll wheel

Should it be possible to use the left/right scroll and a modifier on a wired Mighty Mouse to go back/forward in Safari and Finder, and also to scroll left and right between spaces?

I've just tried to set it up, and nothing is happening. The setup in BTT registers the scroll, but when I try to use the actual binding, it doesn't work. I realise it's an ancient mouse at this point, but I like using it sometimes.
