From the developer:
MySwitch is a handy application that helps you easily switch between running applications using the Function keys. You just need to choose the System Preferences from Apple menu, and then click on Keyboard. Afterwards, you need to select the “Use all F1, F2, etc. keys as standard function keys” checkbox.
