A simple, effective implementation of a usability trick that could solve a great deal. Reading through a End User License Agreement (EULA) is always a pain in the neck, admit it or not there's nobody really reading all the legal thing, scrolling down for pixels and pixels. The fact is you usually have to scroll all the text to activate the next button.

To save you some time, and the additional pain of using the small scrolling bar, the Open office EULA provides a quite useful button: the Scroll Down button everybody. Push the button, and the text will scroll down, that's it.
