IANAG seeks to answer the age-old question: where is the "Any" key??

"But the any key. This is a very special key. It is not like any other key. In fact, it is so different that most people don't notice it on the keyboard. In math, there are some numbers that are like that. For example, if you wanted to do the square root of –9, it would be impossible right? What times what gives you a negative?"
