Some keys don't work.

[ieure]

This code doesn't work, because the punctuation keys to the right of the numerics above the QWERTY can't be bound:

chars = ['-', '_', 'shift+=', '+'];
for (i in chars) {
    var this_char = chars[i];
    $(document).bind('keyup', chars[i], function(event) {
        console.debug("Pressed " + this_char);
    });
}

I think some of specialKeys mappings are messed up.
For example - in the current code "." is mapped to 110, but in fact it's 190.
