Running out of these... :-/

There are a few more unassigned values like 0x07, 0x40, 0x88 - 0x8F.
But anyway it's a matter of time to run out...
Do we plan to add more VKEY?

Maybe it's not a huge concern.  I think that we've covered all of the keys on
Chrome OS keyboards and most or all Internet/multimedia keys now. :-)
