How to Undo Smooth Shading - Blender

Question

Just wondering how to reverse smooth shading in Blender.

When the mesh is smooth shaded it's considerably slower to edit due to hardware overhead.

What are the combination of settings / options to undo smooth shading so I can get back to a hard / 'jaggy' polygon model for faster editing?

In blender 2.8 it's: Select the object then go to the Object -> Shade Flat
