Unassigned Keys

Just an enumeration of the keys I found to be unassigned so far, so that they can be used for your favourite operation/function:

Please add any that you use or find more intuitive. Key combinations, especially! Since my F1-F12 have to be pressed with the “fn” key, I hated the throttle controls immediately. And “fn + F3” + NUM 0 (left rudder) locked my laptop, so had to find a different combo there!
