As for every Edit Mode in Blender, by pressing the
Tab
key, we go out of Edit
Mode, closing the node group, as shown in this screenshot:
The closed node group
The node group is still showing the two BSDF outputs (actually connected to the
input sockets of the Mix Shader node), the name data block, and the
fake user
button (F). This last one is the same as in Blender Internal. It prevents the user
count from ever becoming zero, and therefore prevents the deletion of any
non-assigned material. When you save the file and/or close Blender by assigning
the
fake user
to a non-assigned material, you are sure that it will not be deleted.
This is particularly handy when you are building a material library.

Now click on the name data block of the node group and change the default name,
NodeGroup
, to something else. I wrote
BasicShader
.
