FULL list of JavaScript keycodes

Where can I found the official reference of the key codes in javascript?

Google founds only gappy tables.

Especially I’m looking for the key code of double quote.

If you’re testing for typed characters (as opposed to detecting non-printable keystrokes) then you do not need a look-up table. Use the keypress event and you can get the character code and hence typed character from the event in any major browser:

document.onkeypress = function(evt) {
    evt = evt || window.event;
    var charCode = (typeof evt.which == "number") ? evt.which : evt.keyCode;
    if (String.fromCharCode(charCode) == '"') {
        alert("Double quote typed");
    }
};
