Hello. It doesn't work for me. Whichever key I assign (keyboard or joystick) nothing happens. I attach the log file where I assign two keys, put MSFS in foreground and press the assigned key. It seems to me that even from the log the pressing of the key does not appear.
Thank you.
As info so far the only keyboard keys I've found that will trigger this are the spacebar and the backslash bar key \ | (that's above the keyboard for me). Joystick buttons do appear to work.
Hey - do you have MSFS window in focus when you try to toggle on the first person mode?
