How to save nodes?

When creating a material, I am also creating nodes to control the UVW Tiling/Size.
please see screenshot below:

Of course I want to control the tiling and UVW Size on every single material I create.
For this reason, I don’t want to create over and over again the same nodes.

Is there not a way, to save those three nodes as a template and when opening another material, I can just copy and paste it?

How to do that?

Thanks a lot for any little help!

Technically you would use material functions to approach that, but for the sake of readability you would use material functions for much more complex things (large number of nodes), because if another person reads you graph it would be way faster to understand the “set” shown above, than a material function for that. You might end-up using some more complete features to put as material function thou.
