Where is the "See Through" selecting button in 2.81? In blender 2.81,Layout workspace, Edit mode, Face select,using Box-selecting tool, I try to select all the faces of a cube at once, but only the front faces are selected.
Blender 2.79 had a "See Through" button next to the Vertex,Edge,Face buttons allowing to select all at once .
Is there such an option in 2.81? I could not find it.
It's still there.
Right next to viewport shading options.  

Now it's called X-Ray.
Works in Edit and Object mode.
