Info-next-reference-or-link is a compiled Lisp function in `info.el
'.
(Info-next-reference-or-link PAT PROP)
Move point to the next pattern-based cross-reference or property-based link.
The next cross-reference is searched using the regexp PAT, and the next link
is searched using the text property PROP. Move point to the closest found position
of either a cross-reference found by `re-search-forward' or a link found by
`next-single-char-property-change'. Return the new position of point, or nil.
