-As explained in earlier nodes, the Emacs version of Info normally

+As explained in earlier sections, the Emacs version of Info normally
+hides some text in menus and cross references.  It also replaces the
+@samp{*note} prefix of each cross reference with a more grammatically
+correct @samp{see}.  This is the effect of the default value of this
+option, @code{t}.  Setting this option to @code{nil} disables both
+hiding and replacing of the original cross reference text, and Emacs
+will then display them as they are in the Info file.  If you set it to
+the value @code{hide}, Emacs will do the same as with @code{t}, but
+will also remove @samp{*note} without replacing it with anything.
+Setting it to any other non-@code{nil} value produces an intermediate
+behavior, hiding a limited amount of text, but showing all text that
+could potentially be useful, including the name of the node that is
+the target of the cross reference and its file if it is different from
+the current file.
