About aliases for fields on layouts Zoho CRM

Hi team

   I am managing Zoho Crm, where when parsing a deluge script where I see the following code:

debtCopayment = potential.get("Copayment_to_Cover");

But if I look for the Copayment_to_Cover field in the layout, I can't find it, which makes me think that there is the use of an alias, I have no idea where it is defined.

My question is, where are the aliases of a form field of a layaout defined?

Thanks in advance
Pablo
