Mighty Mouse as Application Switcher
Looking for an easier way to switch between multiple applications? Within Keyboard and Mouse Preferences under System Preferences, you can configure the scroll wheel to act as an Application Switcher. Press the scroll button to bring up Application Switcher, scroll to toggle to the application you want, and hit the scroll button again to switch. You can also double-click the scroll button to quickly switch to the previously active application.
