What command did you do to connect.
If you have the Node Wrangler Addon enabled,
you can use CTRL+T to add a Texture Coordinates and Mapping Node when you have a Texture Node selected.
If you press CTRL+T with a Shader Node selected, it will also add an Image Texture Node.
Oh,
I see now; you mean the Reroute Node.
SHIFT+RMB and then drag over the Noodle. I believe that also works without the Node Wrangler.
Thanks, I will try that tonight. I do have node wrangler activated. Thanks again.
