Discussion
When a user clicks the help button, the certificate panel first checks the delegate for a certificatePanelShowHelp(_:) method. If the delegate does not implement such a method, or the delegate method returns false, then the NSHelpManager method openHelpAnchor(_:inBook:) is called with a nil book and the anchor specified by the setHelpAnchor(_:) method. An exception is raised if the delegate returns false and there is no help anchor set.
