// Key codes are translated from the on screen keyboard to the scan codes
// needed for Chromoting input.  We don't have a good automated approach to do
// this.  Instead we have created a mapping manually via trial and error.  To
// support other keyboards in this context we would have to test and create a
// mapping for each keyboard manually.

// Contract to handle translated key presses from the on-screen keyboard to
