What is your preferred keyboard button layout for playing fangames?

Control + Shift here but since the release of the eighth installement of GME, configurable controls are a thing now.

I never got around to learning how to do that in GME. From the other replies it seems that the Z, X, C layout is naturally the most comfortable for platformers. This layout also naturally places your thumb on the spacebar and your pinky on the shift key.
