This should be "... will be set to InvalidNativeKeycode()." or similar.

[weitao, 2013/09/05 07:49:17]

Done.

This should refer to the DOM4 UI Events spec, e.g. "|code| specifies the DOM4 UI
Events value for the key."

nit: Rename the |key| parameter to |keyCode|, since that's what it actually sets
in DOM language, here and above.

[weitao, 2013/09/05 07:49:17]

Done.

+// TODO: should we have an overload that takes only KeyboardCode or
+// |code| and generates the other one based on US keyboard layout?

[Wez, 2013/09/05 00:16:33]

nit: This isn't really a TODO, so I don't think the comment adds anything.

[weitao, 2013/09/05 07:49:17]

Done.

[Wez, 2013/09/05 00:16:33]

As per style guide, this shouldn't be an override, but e.g.
SimulateKeyPressWithCode().

[weitao, 2013/09/05 07:49:17]

Done.
