# Rename fields with Rename Keys in Duaer

In Duaer, Rename Keys changes field names, not values. Under Keys, set Current Key Name and New Key Name.
## Rename one field

1. Search for Rename Keys and connect it after the previous node.
2. Under Keys, select Add new key.
3. Set Current Key Name to the present name, for example email_address. Dot notation works for nested fields.
4. Set New Key Name to the new name, for example email.
5. Select Execute step. The field name changes. The value does not.

Regex under Additional Options can rename many keys at once. The node warns that a regex can also hit keys you just renamed.

To change values instead of names, use Edit Fields. Refer to [Change fields with Edit Fields in Duaer](/build/edit-fields.md).
## Questions

### Does Rename Keys in Duaer drop fields you did not list?

No. Fields you leave out of Keys keep their names.
