HI John, I cannot get a macro to be displayed in the button drop-down list in FSUIPC5. This relates to Xtreme Prototypes Learjet 25 where they use their own Yaw Damper code and not the default. I want to assign the macro to a GoFlight T8 switch for convenience. There are two buttons on the aircraft’s centre pedestal – Yaw Damper On and Yaw Damper Off. Pressing one also changes the other.  The company uses LVar variables which should be accessible to the user for manipulation in FSUIPC.
