07/25/2020, 10:17 PMok, I’m backing up and decided to start with something easier to get familiar with magic, now I’m trying to make this inv into a tie by moving that square of li to position shown and removing the input (amazing how close these gates are)…. I’m watching some tutorials, but seems hard to proceed without middle button…tips appreciated. Ahá! just discovered ^D and p 🙂

07/26/2020, 1:48 AMok, I may have over compensated. There is no layer selection on that menu though…

07/26/2020, 2:01 AMThe layer assignment is automatic unless you uncheck the "default" button, in which case you can select the layer to use. If the label covers multiple materials like the one shown, you probably also want to set the "sticky" flag, which will force the label to always be on the layer indicated (otherwise magic may get confused by the multiple layers).
