Apologies if this is the wrong place to post my question, but I haven't been able to find an answer.

I have the G551JM (which I love) and want to modify how the function keys operate. Specifically, I want to be able to use their alternate controls (brightness, volume, etc.) without having to hold down the key. My old Dell allowed me to change the mode in BIOS, but I can't find any options for this on my Asus.

Anyone know how I can do this?
