data_navigator.RecordSet.MoveFirst                       ' Move to the first record
data_navigator.RecordSet.MoveLast                       ' Move to the last record
data_navigator.RecordSet.MoveNext                      ' Move to the next record
data_navigator.RecordSet.Previous                        ' Move to the first record
You can also add, save and delete records using the following commands:
data_navigator.RecordSet.AddNew                          ' Adds a new record
data_navigator.RecordSet.Update                           ' Updates and saves the new record
data_navigator.RecordSet.Delete                            ' Deletes a current record
*note: data_navigator is the name of data control
