Info-follow-nearest-node is an interactive compiled Lisp function in `info.el'.

(Info-follow-nearest-node &optional FORK)

Follow a node reference near point.
If point is on a reference, follow that reference. Otherwise,
if point is in a menu item description, follow that menu item.

If FORK is non-nil (interactively with a prefix arg), show the node in
a new Info buffer.
If FORK is a string, it is the name to use for the new buffer.
