The main section of the slots view lists the slot names of the current class. Selecting a slot in this list displays a description of it in the Description list, and you can operate on any number of selected slots using the commands in the Slots menu.
The number of items listed in the Slots area is printed in the Matches box.
If Include Inherited Slots is selected, slots inherited from the superclasses of the current class are listed as well as those explicitly defined on the current class. Deselect this button to see only those slots defined on the current class. You can also configure the default setting of this option. To do this raise the Preferences dialog as described in Setting preferences, then select Class Browser in the list on the left side of the Preferences dialog, and then select the Slots/Functions tab to see the Include Inherited Slots option.
