In my experience, all or most all of the default keyboard key bindings are the exact same as in FSX: Ctrl+E starts the engines (if you choose not to do so manually), Shift+M controls the electrical, Ctrl+Shift+C and V controls the cowl flaps, G controls landing gear, F1 through F4 controls throttle (Ctrl+ for prop pitch, Ctrl+Shift+ for mixture), F5 through F8 controls the flaps, Shift+P controls pushback, Y for slew, and so on...
