Presumably the original post was made facetiously, but since a lot of people are talking about special characters in the comments:
I can't confirm anymore, but besides all the alt shortcuts in the comments, in Windows it used to be that you could open the Character Map from the Start menu, then either copy any character from a chart or select the character to see its alt code.
There have been enough times that I've stated something obvious and been declared mistaken by the original poster that I've learned to hedge my bets. Also, if I pretend to be ignorant of some obvious things, it can be funnier.
If you'd prefer it to be framed another way, I'm a coward.
