To add a class and all of its subclasses to a list of selected classes
Right-click on the class in a list of classes that are available for selection (for example, the ModelEntity superclass in the Classes list box at the left of the Capture view of the Node Sampling activity group). Use the Ctrl or Shift key to select a group or range of classes, respectively.
Select the Add Selected Class (include subclasses) command from the popup menu that is then displayed. This command is available only when the selected class is a superclass.
The selected class and all of its subclasses are then moved to the list of selected classes at the right of the view (for example, the Selected Classes list box on the Capture view of the Node Sampling activity group).
For details about removing a selected class from a list, see "Adding an Item to or Removing it from a List", earlier in this chapter.
