I hereby present you with the spring-loaded scroll wheel: It doesn't do full revolutions, but instead functions like the pitch-bend wheel on a MIDI keyboard. Springs always return it to the centre position upon release. If you pull it down from the centre position, using your scrolling finger, by just a very small amount, your mouse constantly sends signals to your computer, indicating a scroll wheel continuously being turned downwards, very slowly. The more you pull or push, the faster the scrolling becomes. Now you can scroll any distance, both super quickly and precisely, without touching your wheel more than once.

I don't have the ressources to apply for a patent; but you read it here first, I am in fact the inventor of this technology.
