Ralph,
Both of the above answers are correct. The more important question would be if you would rather just view them, or modify them. If you wish to modify them, then definitely open the Data Identifiers and modify as needed. Be casreful when modifying the templates included. One suggestion we generally give customers, is to recreate the built in Data Identifier, then make changes to ensure you always have the original still intact in it's default configuration. There is no way to "recover" them once you've modified them.
