As previously discussed, Chromium already has this table; please add an
embedder-provided API that Blink can call to do any necessary remapping; that
way Chromium can just pass in e.g. the nativeKeyCode and let Blink call back out
to turn that into DOM3 code.

[Habib Virji, 2014/10/27 16:48:36]

I have added a new embedder API, this file is removed now. 

Please have a look and suggest if changes are okay.
