I have made a Google Sheet containing all available controls in the game.
View the FS2020 - All Controls Sheet right here!
I will keep the list updated if changes are made in future patches.
The reason for making this is list, is that i am working on a home cockpit and needed all the available controls in Flight Simulator 2020 in one handy document. I thought i’d share it, so that it might help other people.
edit: Changed the link to a new public link (again, sorry).
