Can the Mouse Scroll Wheel Be Used as a Trigger?

SteerMouse is a Mouse driver, correct. But it is not a needed one, if we could use scroll wheel steps as trigger in KM. (I know that SM offers way more things, but I'm not talking about these, and I do not really need these, they can be reduplicated (except for the speed/acceleration settings) with KM or similar programs.)
