I have a function key template (anyone remember those?) for internet explorer. It seems to be pretty old, since none of the function keys in newer IE releases actually does what is labeled on the template. Actually, I'm not sure if that's true, because there aren't really any words (like on the old wordperfect templates), just icons. F1 is a book with a question mark on it. Obviously that's the question mark book button, er, I mean the help button. F12 actually has words; it says "hot keys". I think that increases the temperature of the keyboard. F9 is a folder with a five-point star, obviously a poorly drawn pentagram. F10 is a sun dial; who knows what that does. F11 is a satellite dish for those users with satellite internet connections. F2 is the internet explorer icon, which is obviously useful if you want to start internet explorer from inside internet explorer. F3 and F4 are less interesting, just arrow buttons, which I guess are back and forward. F5 sorta looks like the refresh icon, which doesn't really make me think of refresh, but I still recognize it. F6 is probably the best icon of the bunch; it clearly looks like a letter and an envelope, so I'll give the designer credit for making F6 the email key. F7 is a house, and that probably takes the user home.
But the best one of all is F8, which is labeled "IQ 99". WTF?!?
