You can create a new record, in a table, based on the contents of the current record. This may be useful if, for example, you are adding several contacts from the same company to your database.
Rather than re-type address details, select the Duplicate Record command from the Record menu (in Grid View you must select the whole record first by clicking in the left row bar, but in Form View it is sufficient to have the form on screen).
This will create a new record with the details of the current record copied to it. You can then edit the new record as you like.
