So, I'm staring at my mouse the other day (a Microsoft optical mouse--blasphemy, I know…) during a bad case of coder's block and wondered what would happen if I pressed on the scroll wheel. In Windows, doing that gives you a fancy way to scroll the screen up and down as a variable speed by moving the mouse up and down.
Being the brave computer that I am, I pressed it and was pleasantly surprised to find that in OS X this does the same thing at Cmd+Tab which is switch to the last used application.
