WebAccelerator object associations

I'm a newbie to the WebAccelerator product and trying to set it ip. After reading through the configuration guide and tutorials I am at a lost as to how the defined Application, Policies, and HTTPClass associate with each other. There does not seem to be a field under each of the objects to identify the name of the other objects.

 

 

How does the F5 know which WA Application and Policies definition to associate a HTTPClass with or vice versa?
