Okay, some pics of SA profile keys on an actual keyboard.
First, some images of all profiles.
Row1 - Row2 - Row3 - Row4
Some more shots
Images of Row3 only - you may be able to see the difference against the regular rows in the background.
Numpad with all Row3
(I think that zero key is upside-down...)
Full keyboard shot
Edit: the PCB for this keyboard is not fully aligned with the top case, in the shots of the number pad you can see the PCB is lower towards the front of the case.
