event.keyCode
values for keydown and keyup events in
Opera 11, Internet Exlorer 8.0, Firefox 3.6, Safari 5.0, and Google Chrome 10.
(If you are interested in key codes for older browsers, please refer
to the W3C Working Group Note
Legacy Keyboard Event Properties.)
Common key codes that are relatively safe to use across browsers are shown in black.
Key codes that differ across browsers are shown in red.
Do not use this table for character codes keypresskeypress character codes are not key-specific and may be enirely different from keydown/keyup key codes.
