I've searched the kneeboard on FS X and I can't find any information on what keys to push for MD-80 Nose Wheel Steering. I would appreciate any help with this, and thank you.

Thank you very much for your help.

I have been away from FSX and aviation for quite some time, and it seems I have forgotten some of the basics. I have FSX (obviously) and MDC MD-83 twinjet airliner installed on my Desktop PC. When I input my "free flight" data for a ground airport, I get a cockpit with engines running. I need to know how (what keys to push) to turn the power plants off so as to simulate a ''cold and dark" aircraft. Thank you for helping to refresh my memory
