Jonathan Turner has released Keyboard Sith, a tool that disables your mouse and forces you to use the keyboard. Why would you want to do this? When I have taught courses on test-driven development and refactoring, I have noticed that the programmers that avoided the mouse and code completion facilities from their IDE (e.g. IntelliSense) always finished the exercise first. These programmers simply learned the keyboard shortcuts of their IDE to efficiently navigate around and simply learned to type their code faster than any browsing tool could complete it.
