RenamePrimaryKey method on new table

Hello, 

I've create a very simple table with one field that has a primary index assigned to that table. 

How do I get the button Rename when you go to the record information of that field.

It seems to be something about the table method RenamePrimaryKey, but I cannot find how to create this method on a new table. 

When looking at the existing tables that have such a method, I cannot find a generic way to create such a method. 

Maybe I'm missing something else, but so far I cannot find anything. 

Thanks in advance, 

Peter
