Info-find-node

Info-find-node is a compiled Lisp function in `info.el'.

(Info-find-node FILENAME NODENAME &optional NO-GOING-BACK STRICT-CASE)

Go to an Info node specified as separate FILENAME and NODENAME.
NO-GOING-BACK is non-nil if recovering from an error in this function;
it says do not attempt further (recursive) error recovery.

This function first looks for a case-sensitive match for NODENAME;
if none is found it then tries a case-insensitive match (unless
STRICT-CASE is non-nil).
