oh, forgot about that... I use mouse buttons for altitude and throttle, only steer with ring and index finger (A/D).
With the new system, I would bind tools to the keys (3), (W), and (S), the column between A/D. So, that would leave my middle finger dedicated to tools, and pinky (SHIFT) for voice chat. Woo hoo, all five fingers have a clear job to do in combat!
p.s. speaking of which, GOI's default keyboard bindings are a thing of cosmic horror. Seriously, for example how am I supposed to change altitude (S) and chat (X) and turns left (D) all at the same time? It's a pretty common combination that is horribly inconvenient to do.
