The top row of the MS Surface Type keyboard mostly consists of special keys for increasing volume, searching, accessing settings, etc. But if you hold the "Fn" key, then that row becomes the standard function keys (F1 - F12). I'd like remap the keys so that without "Fn" pressed, it is the standard F# keys, and with the "Fn" press, it is the special key. So basically flip what the key is for "Fn pressed" vs. "Fn not pressed".
What is the easiest way for me to accomplish this?
