Sorry if this is obvious, or if I'm just doing it wrong, but I can't figure out how to get the Linux build (build 5.3.5 running in Ubuntu) to orbit around a focused game object. On pressing 'F' the editor cam zooms to the object just fine, but holding ALT and the Right-Drag seems to open a popup menu instead of orbiting behavior I was expecting (my muscle memory says this is proper key combination to Orbit around a selected object in the Windows editor). Right-Drag alone rotates the camera around the editor camera pivot just fine. Also, ALT W,A,S,D seems to fly around the scene as expected. Dose the Linux version of Unity Editor have a different key combination for Orbiting from the Windows version?
