Glossary:Hook node

hook node

place that determines where new elements are added in the Contents window (e.g. with Add new). A hook is a knowledge tree node to which new elements are added (as children). The hook node is either the same as the root node, or is a child of the root node, or is a descendant of the root node. Once the children limit of a hook is passed, a new hook is chosen. The newly chosen hook is always a descendant of the root of the current concept group. If SuperMemo runs out of branches that might become new hooks, it will restructure the concept branch and start a new level of branches under the root node with new space for new hooks and new elements.
