Where can i find a full list of %% CODES for Invoices

I am making custom ZOHO Invoices and the drop down list does not show all the available codes, especially for contact information. (Also Tax information).

I am specifically looking for the %% that refer to the CONTACT NAME. %CustomerContactName% ?? Please update your %% list of codes and can you please supply me with the CONTACT NAME codes?
