Hi allI know lots have people have been asking about the airstairs key assignments for the PMDG737 so I apologise for my dumb question.My problem is that I have assigned the keys Ctrl+F10 to "Extend Concorde Nose/Visor Fully" and Ctrl+F9 to "Retract Concorde Nose/Visor Fully" as advised. Pressing Ctrl+F10 extends the stairs fully, no problems but Ctrl+F9 will not retract the airstairs. Absolutely nothing happens. I've tried different key assignments so I know it's not my keyboard playing up. Does anybody have any ideas? Wondering if some other FS-Addons that I installed could have fouled things up? Thanks guysNathan

Change it to Shift + F9/F10 will work fine :)

Works like a charm so thanks very much for that. RegardsNathan
