This is a list I compiled which contains every possible KeyCode that Visual Basic can detect. A KeyCode is different than a KeyAscii value. A KeyCode can be thought of as an individual key on your keyboard. Every key on your keyboard has it's own unique KeyCode value. Keys that share values such as 1 and ! have the same KeyCode value because they are physically the same key. KeyCodes can range in value from 0 to 255. If you're looking for other charts, I also have a KeyAscii chart, a KeyCode Constants Chart and a downloadable program called KeyAscii & KeyCode Finder that can tell you the KeyAscii and KeyCode value for any character.
