To find out what a certain button or lever in the cockpit does when you operate it with the mouse, do this:
- Activate MSFS developer mode
- Open “Tools->Behaviors”
- Click back into the sim window
- Hover your mouse cursor over the button or lever that you want to investigate and press “Ctrl G”
This will bring up the behavior code in most aircraft. Near the end of the list of components there are usualls things like “Asobo_GT_Interaction_LeftSingleCode” that contain the code that MSFS executes when the associated mouse event is received - and that is what you replicate in AAO.
In the future (as soon as the bug with the input events has been sorted out by Asobo) this will be mostly obsolete, because then AAO can read the existing input events directly from the aircraft and you can select them from a list. At the moment (MSFS 1.34.16.0) this only works when developer mode is on (check out the chapter about the MSFS InputEvents in the AAO manual)
