The ALT key can help you access alt codes, or characters that aren't readily available on a normal keyboard. These codes can be used to write in foreign languages, mathematical equations, or to add fun symbols to your messages. Below ☟ is how to do it on a PC or a Mac, then a list of symbols such as π, ♫ and ♥.
