I think this API should be merely about translating the value, because
this way you're just blocking a synchronous API for no apparent benefit. I
believe it should return instantaneously. On the other hand, I'm just wondering
what value it brings having an API translating keycodes, but I guess for
consistency reasons, we can happily introduce it.

Otherwise looking good.
