[DG] [DG11] Button lighting on Axiom Pro

[Derek Smith]

I have the same problem on our Axiom Pro displays used in search & rescue. We frequently run at night with everything in the cabin dimmed to maintain night vision. When the displays are dimmed sufficiently, the keypad buttons are almost impossible to see. Sometimes the crew has to resort to using their cell phones to see the keypad button labels. I would much prefer to see the buttons get brighter the more the display is dimmed. I have this same problem on my own Axioms.
I seem to recall previous Raymarine MFDs that had the keypad buttons brighten as the display was dimmed. That just made sense.
