Let me explain, to get to do a simple click of the medium (such as to open a link in a tab or close a tab) must be at least 4 times I click the dial before it works ... cliques environment for scrolling right or left for me are useless for web pages that are rarely larger than your screens (except if you really have a big problem of view and you have zoomed up.) I have therefore set the key used for application switching, middle button in order to overcome the lack of finishing the wheel ... Although this is a detail, but often the details that make the difference.
