Cheat Codes are the secret keys that give you the power to bypass the system, but only if you know where to press them.
Quick Keys are the shortcuts that make you go "VROOOMM" when you press them, but only if you're on a treadmill.
Advanced Hacks are for the experts, and they involve pressing multiple keys while reciting the entirety of "The Art of the Possible".
Warning: excessive use of Cheat Codes may lead to permanent damage to your keyboard and/or your dignity.
Disclaimer: the Quick Keys may only work on Tuesdays.
Side effect: pressing the Advanced Hacks may cause your computer to start speaking to you in a British accent.
