This is a nice feature, but I think its implementation is too heavy: to display just one node it has to visit several other nodes. It would be more optimal to build a tree of all Info nodes after visiting the first node and to use this cached structure during displaying an Info node. -- Juri Linkov http://www.jurta.org/emacs/
