How to call up Forms from Datasheets

I notice that in the sample database that comes with Access (Northwind 2007)
it is possible to call up a Form for any particular record directly from the
Datasheet. For example in the "Customers List" in Northwind it is possible to
click on any of the fields for any customer record and call up the Form for
that customer. As my databases operate now I must 1) check the ID number for
a particular record in the datasheet view, 2) switch to Form view in the
Navigation Pane, and 3) enter the ID number in Form view in order to see the
Form for any particular record. Can you guide me as to where, for example on
Help, I might find instructions on how to alter my database design to provide
this facility?
