keyboard

Apple's keyboards have a new key, with § and ± symbols on it. Can somebody tell me what these keys are for, and where I should use them?

I am aware the symbols have mathematical uses, but I assume they must do something important as well to be on the core keyboard. Or are they just the 'Scroll Lock' of the Apple world?
