My Macbook Pro has a lit keyboard.
I can change the intensity of the keyboard light using Fn F5/F6 on the Macbook's keyboard.
My Apple Wireless Keyboard, Third generation (A1314), has no markings on F5/F6 for changing the keyboard light.
Sure enough, pressing Fn F5/F6 on the wireless keyboard does not affect the keyboard light.
(Fortunately, changing the Macbook's display intensity and volume both work fine on the wireless keyboard, where the inscriptions on the keyboard say they should.)
Is there a way to configure the wireless keyboard to control the keyboard light?
