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
onkeypress event, while the key values, including
navigation and function keys, are available from
onkeydown and onkeyup events.
Table B-1 lists all keys on a typical U. S.
English keyboard and their corresponding key codes.
