Have you ever wanted to put funny characters into your blog comments, but didn't want to search the 'net for an example to cut-and-paste? Well, it turns out that there's an easier way -- just use the "Alt" key. It turns out that if you have the Num Lock on, you can hold down the "Alt" key on your keyboard, and then type in numbers on the number pad (the numbers at the top of your keyboard won't work) -- when you then release the "Alt" key, a funny character may appear! Here's what you get for 1 through 31:
☺☻♥♦♣♠•◘○◙♂♀♪♫☼►◄↕‼¶§▬↨↑↓→←∟↔▲▼
Numbers 32 through 127 are for normal keyboard keys, and you can get more funny symbols by typing in 128 through 256. For example, the "infinity" symbol is 236: ∞
(You can find out what you'll get for 128 through 256 on this page. The symbol associated with 176 is really weird: ░ )
Have fun in the comments!
