Appendix A. Keyboard Event Character Values
Keyboard events in recent
browsers provide information about the keys and, where applicable,
about the characters corresponding to the keys. Character values may
be read from the onkeypress event. The following
table reveals the codes for characters in the lower ASCII character
set. Some of these codes are for action keys (such as Backspace and
Tab), whose character values are also in this range:
|
Backspace
