It's an Easter Egg (i.e. something the Facebook developer added for fun that only appears if you know how to find it.) This key sequence is called the Konami Code, which is a cheat code that appears in many video games. There is a whole website of sites where this code will bring up hidden features: http://konamicodesites.com/ - and you have to enter the code to access the website!
