When I flew with FSX there was addon “FsParrengers” or “PassengersX” where was nice feature. I can set autopilot with numpad numbers. For example if I wanted to set heading to 350 I pushed “h” and then 3, 5, 0. I miss that feature. Now i have to scroll knobs with assigned buttons or mouse wheel. I tried to search that kind of addon, but didn’t found one. Is there?
PMS50 make the freeware GTN750 mod for MSFS, they also make a Premium payware version with a fully configured autopilot in which you can enter a heading using an on-screen keypad:
