The Slot Icons
The icons in the Slot Browser and the Template Slots pane give information about the slots. There are two types of icons: slot icons and hierarchy icons.

A blue rectangle indicates a slot. In the Template Slots pane, this icon means that the slot is direct; that is, it was attached directly to the selected class. responsible_for is a direct slot. | |
(Template Slots pane only) A bracketed icon means that the slot is inherited from one of the selected class's ancestors. Inherited slots can be edited, but not deleted; there are also some restrictions on the edits that are allowed. | |
