I am an SWE newbie and I have struggled a bit understanding terminal strips/blocks. I have found a lot of content on the web, but I still don't have a good understanding of the syntax required to define circuits. I believe that a comma tells the system that the terminals on either side of the comma are connected together, but I have not found a concise resource that explains how to enter text in this area. In my attachment I am referring to the green oval in general and the red oval in particular. Many Thanks!
