How can i add Windows key + Fn + Printscreen on nunber 12 button of my razer naga pro. I like to take and save screenshots with just one click. i managed to do that with my old Synapse on my naga epic chroma mouses. But i dont know how to do that on new Synapse. PS i bought two razer naga pro few days ago so i am new on this.

Thank you! :)
