 // Chrome relies on the underlying OS to interpret modifier keys such as Shift,
 // Ctrl, and Alt. The Linux input subsystem does not assign any special meaning
 // to these keys, so this work must happen at a higher layer (normally X11 or
 // the console driver). When using evdev directly, we must do it ourselves.
