noders can link to a specific writeup within a node by appending "(person)", "(place)", "(idea)" or "(thing)" to a pipe link. for example, the pipe link codice_3 links directly to the writeup of the type "thing" within the "wiki" node. if the node contains more than one writeup of the specified type, the pipe link returns a "duplicates found" page linking to every writeup of the specified type within the node.
