NODE Editor Add is all blank

Hi All,
I have seen a few posts that show the node editor view populated with all kinds of maya like goodies.
My question is how do you do that? I launch Blender and switch to Node editor and click the Add item in the menu and it is all blank. There is nothing I can add.
Is my blender install broken?
How do you use this screen?



There are two screen modes for nodes, material, and composite. Chances are, you are in material mode, and you haven’t assigned a material to anything yet, so there is nothing to add to. At the bottom of the node editor window, there are 2 buttons: the ball is for materials, and the face is for composite nodes.

Check out the following:

Best of Luck!!

Switch on the use nodes button.
