There's a slight nuance here, the keyboards for Hayato and Spherion
are not the same one. Hayato follows the keyboard design of older
Chromebooks, such as Kevin:
back, forward, refresh, zoom, scale, brightness up ...
(the right side part is the same)
Spherion's keyboard layout matches what you have above.
Also, "zoom" should probably be full-screen, even though the two
map to the same keycode.
