The Numpad works or not, depending on the status of the NumLock key, which would alternatively require using (or not) the Shift key. You can also use the arrows keys.
And the main difference compared to FSX/P3D, is you need to press ENTER to exit any editor, not Y, because the editors in MSFS don't use Slew mode, which in MSFS forces to use a specific camera, so the sim is not in Slew, but uses the Drone/Showcase camera instead.
