To duplicate a rule set:
1. Right-click on the rule set that you want to duplicate in the Browser pane of the Rule Set window and select Duplicate on the drop-down menu that appears.
A copy of the rule set with the same content appears in the Browser pane.
The duplicate feature saves time when you want to create a new rule set that contains similar content to ones already created. After it is created, you can customize the new rule set.
