PrF UG slots slot hierarchy
The Slot Hierarchy Window
The Slot Hierarchy window in the Slot Browser displays the slots for the project and allows you to rearrange your hierarchy using "drag-and-drop". By default, the Slot window displays the slot structure of your knowledge base, with all slots shown as descending, directly or indirectly, from the system slot :THING.
Description
This window shows the following:
Subslots appear below their superslots and indented to the right.
Hierarchy icons indicate how much or how little of the hierarchy is displayed. An "expanded" (
) icon
means all direct subslots of the slot are displayed.
A "collapsed"
(
) icon
means the slot has direct subslots which are not currently displayed.
Clicking on either icon toggles it to the other.
If no icon is displayed, the slot has no direct subslots.
Tip: You can also display all slots below a slot by right-clicking the slot and selecting Expand from the cascading Slot menu.
The currently selected slot is shown with a highlight.
Slots with more than one superslot appear more than once in the tree.
Slot icons show information about your slot.
If a slot has an inverse slot, the name of the inverse slot is shown after the slot name:
