nodes-how to assign texture as value?

at the top of the material nodes section of the release notes, there’s a pic of combined materials, with the screenshot having 2 material nodes, a mix node, and a value node, that has a texture assigned to it. i am trying to reproduce this, but my understanding of nodes is very limited, and i have been unable to figure out how to assign a texture to the value node. any help in accomplishing this would be appreciated.

It’s not a value node, it’s a texture node. But the node is shown in it’s minimized form.

ah, that would explain it. thanks.
