Ever tried to copy a field rename from one select tool to another, or from one summarize tool from another.
Have you noticed that it doesn't work?
I think it should. 🙂
i.e., if you click on the rename box ("Total") and enter ctrl-c, when you enter ctrl-v in the other tool, it pastes this:
Field2 Sum Total
not just the name "Total"
Instead of just the renamed field "Category", the select tool pastes this:
True Field1 String 1 Category
