Basically what it would look like is that you can view your "B" button map on a browser that maybe in another screen, another computer, a tablet or your phone.
I actually just remember this since I stumbled upon a Razer Artemis picture and saw it had a screen on there.
EDIT: I forgot to add that this should not display anything if they switch to 3PV mode.
