Blender 2.8 display a subdivided view of the mesh, but without applying subdivision to the object When I press 3 on Maya it shows me a subdivided version of the mesh without subdividing the mesh, how can I achieve the same result in Blender 2.8? also, I should mention I'm emulating Keyboard Numpad because I don't have a big traditional keyboard.
Ctrl + n where n = a number so  Ctrl+ 2 means a subdiv modifier with 2 subdivisions

Ctrl + 0 keeps the modifier but does not show the subdivisions.
