The Contents window presents the tree structure of knowledge hierarchy in the currently used knowledge system. This structure can be edited and expanded by means of drag-and-drop operations, options on the menu, etc. (note that full SuperMemo has to be activated with Tools: Options : Data access : Access mode set to Full Access):
View - makes it possible to edit the currently selected element by loading it into the element window
Add - adds a new child element to the set of children of the currently selected hierarchy element
Sibling - adds a new sibling element to the set of children including the currently selected hierarchy element
Insert - inserts a new element at the place of the currently selected hierarchy element
Delete - deletes the currently selected hierarchy element and all its children
The Node tab at the bottom of the hierarchy window provides the following operations on all node children, or optionally, on all node descendants:
Hook - make the currently selected element the hook of the current category. Each time Ctrl+A is chosen, new item will be appended to the hook node as its child. This makes it easier to add a large number of simple items to the knowledge system without the need of specifying their position in the knowledge system. Use Tools : Categories to see the hook of each category.
Commit - memorize children of the node, i.e. enter them into the learning process.
Reset - remove children of the selected node from the learning process and add them to the pending queue of element awaiting memorization.
Dismiss - ignore children of the currently selected element in the learning process. This operation is useful in making sure that a collection of topics belonging to a given node does not take part in repetitions. All children of the dismissed topics, however, will by default remain in the pending queue of elements awaiting memorization.
Undismiss - override the Dismissed status of children of the currently selected element and add them to the pending queue, i.e. the queue of elements awaiting memorization.
Item - give all children of the selected element the item status. The item status is important when using Review in the element window. Review begins repetitions of all item children of the currently displayed element, and it skips all topic children.
Topic - give all children of the selected element the topic status. Note that this will make the option Review have no effect until some of the converted children receive the item status again (i.e. have their Topic pop-up menu item unchecked). Most importantly, topics do not take part in repetitions. They are only presented once before their associated items are memorized.
The Data tab displays the number of children, the number of descendants, the status, type and the requested forgetting index of the currently selected element in the Contents window. The status can assume the following values: Dismissed, Pending or Memorized. The type can be topic or item.
The Title tab is used to edit element titles in the Contents window.
You can edit the structure of the knowledge hierarchy by dragging particular elements. The combo box present on the Contents window toolbar determines what exactly happens with elements dropped on the hierarchy:
* by default, element A dropped on element B replaces element B in the hierarchy (option Replace the target in the combo box)
* if Add as last child is set in the combo box, element A dropped on element B is moved to become the last child of element B
* if Add as last sibling is set in the combo box, element A dropped on element B is moved to become the last sibling of element B
* if Transplant children is set in the combo box, all children of element A droppend on element B are moved to become children of element B
* if Transplant partly is set in the combo box, children are transplanted as in Transplant children with this difference that only a limited number are moved. The rest remains in place
