Type a special character in any document

Windows has all kinds of special characters built in - characters that you don't see on your keyboard. Here's how you access them.

First, make sure your NUM LOCK is on. Then, hold down the Alt key and type a number, such as 164, on the number pad of your keyboard. See the character that just appeared? If you typed 164, you saw the letter "n" with the squiggly line over it (used when writing in Spanish). There are all kinds of different characters available to you - you just have to know the codes.

And for your reading pleasure, here is a chart with all of the codes.
