Anywhere nodes
Anywhere nodes are special nodes which are automatically linked from all other nodes. This allows for creations of sculptural hypertext.
The node rules in an anywhere node can specify conditions for when the anywhere node is available. When an anywhere node is created, one rule is automatically added to the node rules. This rule contains the special enable links to this node from anywhere action. As long as this rule's conditions are satisfied, a link to the node will appear at the bottom of every other node. The name of the anywhere node will be used for the link text. The node rules on an anywhere node which contain this special action are evaluated every time any node is entered, so that the links can be added to the node.
Note that anywhere nodes can contain links with rules having Update text and Update fact actions, but may not have Follow link to or Show in popup actions. As a result, once a reader "enters" an anywhere node, there is no way for the reader to get back to the "normal" nodes in a story other than by using the Back button.
