Info-hide-note-references is a variable defined in `info.el'.
Its value is

If non-nil, hide the tag and section reference in *note and * menu items.
If value is non-nil but not `hide', also replaces the "*note" with "see".
If value is non-nil but not t or `hide', the reference section is still shown.
`nil' completely disables this feature. If this is non-nil, you might
want to set `Info-refill-paragraphs'.

You can customize this variable.
