Edit Menu > Add Rule 
Opens the Rule Properties Dialog, where you can create a new rule. In the dialog, you can either create a rule name or proceed with defining rule properties. If you only create a rule name and close the dialog, in the tree view of the main Rule Manager window, the software inserts the rule name below the active folder. If you select another rule and use the New Rule command, the software creates the new rule in the same folder to which the selected rule belongs.
