The ToggleSmooth tool is used to quickly turn a flat flat shaded, unsmoothed mesh into a smooth shaded one, from both - edit and object modes.
Two workflows are supported: Korean Bevel and SubD, depending on the presence of a Subdivision modifier.
Using Toggle Smooth
Korean Bevel Smoothing, by default Overlays are toggled as well
SubD Smoothing of a single mesh, and entire groups, by default Overlays are not changed
