Web applications are becoming more and more like “normal” desktop applications. Of course, they are more and more functional, but smooth user interface acts the primary role. So we have drag and drop, autocompletition, and much more. Many of those nice features got possible only with help of AJAX. This page, however, is not about AJAX (or any other buzzword). It is about rather simple user input method — mouse wheel.
