I have this keyboard and the only thing that (for me) is really annoying is that by default the fn keys are enabled. So If I need to reload a page (F5) I have to press the fn. If a press the fn**key alone it enables the F buttons but the light in the **fn key is always on (what I suppose is not good for the battery)
Is there a way to invert this behavior? I have tried Caps+fn and keep FN pressed 10 seconds without success.
