When my laptop is connected to my Apple Keyboard, I can control the brightness with the F1 and F2 keys on my external Apple Keyboard. However, when I connect an external monitor to my MacBook Pro, the F1 and F2 keys no longer work.
Is there a way to control the brightness of my laptop's screen (NOT the external monitor) with my external Apple Keyboard even when an external monitor is plugged into my MacBook Pro?
I have the late 2008 uMBP.
