@anchor
: Defining Arbitrary Cross-reference TargetsAn anchor is a position in your document, labeled so that
cross-references can refer to it, just as they can to nodes. You create
an anchor with the @anchor
command, and give the label as a
normal brace-delimited argument. For example:
This marks the @anchor{x-spot}spot. ... @xref{x-spot,,the spot}.
produces:
This marks the spot. ... See [the spot], page 1.
As you can see, the @anchor
command itself produces no output.
This example defines an anchor `x-spot' just before the word `spot'.
You can refer to it later with an @xref
or other cross-reference
command, as shown. See Cross References, for details on the
cross-reference commands.
It is best to put @anchor
commands just before the position you
wish to refer to; that way, the reader's eye is led on to the correct
text when they jump to the anchor. You can put the @anchor
command on a line by itself if that helps readability of the source.
Spaces are always ignored after @anchor
.
Anchor names and node names may not conflict. Anchors and nodes are
given similar treatment in some ways; for example, the goto-node
command in standalone Info takes either an anchor name or a node name as
an argument. (See goto-node.)
