Appendix B. Keyboard Key Code Values

Key codes are numeric values that correspond to physical keys on the keyboard but do not necessarily correspond to a particular character. For example, the A key on the keyboard produces the same key code when pressed, even though its character code might be 65 (uppercase A)or 97 (lowercase a), depending on whether the Shift key is down at the same time. Key codes are not influenced by modifier keys. Character values (see Appendix A) may be read from the keypress event, while the key values, including navigation and function keys, are available from keydown and keyup events. The following table lists all keys on a typical U.S. English keyboard and their corresponding key codes.
