Secondary Button

• To create your "Secondary Button" assignment, create a joystick or keyboard button assignment for 'PROPELLER SYNC (ON/OFF)' in the FSX 'SETTINGS - CONTROLS' menu.
• You can select any Joystick or Keyboard assignment (or both).

IMPORTANT:  FS2Crew cannot use the same key assignment also used with any PMDG 737 NGX Key Command function, or the Secondary Button will not work! 

So, for example, if you use "C" as your keyboard assignment for the Secondary Button, you cannot use "C" for any PMDG 737 NGX KEY ASSIGNMENTS.
