2. Backlighting disabled
   There are two factors that will disable backlighting:
   
   When your keyboard has only 10% of the battery left when you try to enable backlighting, this message will appear. If you want the backlight back, plug in your keyboard to charge.
   
   When the environment around you is too bright, your keyboard will automatically disable backlighting to avoid using it when unnecessary. This will also allow you to use it longer with backlight in low-light conditions. You will see this notification when you try to turn backlighting ON.
3. Low battery
   When your keyboard reaches 10% of battery left, backlighting turns OFF and you get a battery notification on the screen.
   
4. F-Keys switch
   Press Fn + Esc to swap between Media keys and F-Keys. We’ve added a notification to let you know you’ve swapped.
