Matt Allington notes a key feature in Tabulor Editor 3:
Today I am talking about Macros in Tabular Editor 3. This is a new name for an old feature. In Tabular Editor 2, this feature is called Advanced Scripting (a term I actually prefer, but oh well). I think one reason for the name change is there are now multiple types of scripting, including the new DAX scripting feature (I covered that as a key feature I love in the article linked above).
