There are four different cross reference commands:
Used to start a sentence in the printed manual and in HTML with ‘See …’ or an Info cross reference saying ‘*Note name: node.’.
Used within or, more often, at the end of a sentence; produces just
the reference in the printed manual and in HTML without the preceding
‘See’ (same as
@xref for Info).
Used within parentheses, at the end of a sentence, or otherwise before punctuation, to make a reference. Its output starts with a lowercase ‘see’ in the printed manual and in HTML, and a lowercase ‘*note’ in Info. (‘p’ is for ‘parenthesis’.)
Used to make a reference to an Info file for which there is no printed manual.
@cite command is used to make references to books and
manuals for which there is no corresponding Info file and, therefore,
no node to which to point. See @cite.
