The current way is fine, although it might be user friendly to call it "original scrolling" which is off by default since most people seem to prefer another scroll direction. (So for them the controls are inverted already)

Well I wanted to keep the spirit that we use the original behavior as the default. And the request was

Ohne invertiertes (rechte) Maustaste-Scrolling ...

So I guess "inverted" has already some notation which we can keep here :)
