Thanks Pete for your reply. All these 3 events ("Alternate Static Source - on/off", "Autofeather - arm/off" and "Propeller Sync - on/off") are present in my FS Settings-Controls Menu. These events could be created (?) when I installed the brand new FS2Crew PMDG 777, because they are used as mentioned in FSCrew777 Manual, to assign the Main Panel Button, Main and Secondary Buttons. I can send to you that Manual pdf if you prefer. These events don't exists in the list of "FSX Controls" document in my FSUIPC Documents folder. Sorry if I wasn't clear in my statment. English it's not my mother language. It would be nice if you can create this new events for those that only use FSUIPC events. Thanks, Carlos
