The “alt” key, located on both sides of the “spacebar” of your keyboard, is a modifier key that when used in combination with the “numeric keypad” has special powers. Those special powers being the ability to type special characters. For example if you wanted to type the copyright symbol “©” , you hold down the “Alt” key and type “0169” on the numeric keypad and the symbol will magically appear.
You can even create mini pics to use in your chat sessions or at the end of an email, etc… when using the “Alt” key.
