For example, in the sample menu cross-reference below, the single colon separates the label from the target. </p> <div class="example"> <pre class="example">* Foo Label: Foo Target. More information about Foo. </pre></div> <p>Note the ‘<samp>.</samp>’ which ends the name of the target. The ‘<samp>.</samp>’ is not part of the target; it serves only to let Info know where the target name ends. </p> <p>A shorthand way of specifying references allows two adjacent colons to stand for a target name which is the same as the label name: </p> <div class="example"> <pre class="example">* Foo Commands:: Commands pertaining to Foo. </pre></div> <p>In the above example, the name of the target is the same as the name of the label, in this case <code>Foo Commands</code>. </p> <p>You will normally see two types of cross-reference while viewing nodes: <em>menu</em> references, and <em>note</em> references. Menu references appear within a node’s menu; they begin with a ‘<samp>*</samp>’ at the beginning of a line, and continue with a label, a target, and a comment which describes what the contents of the node pointed to contains. </p> <p>Note references appear within the body of the node text; they begin with <code>*Note</code>, and continue with a label and a target. </p> <p>Like ‘<samp>Next</samp>’, ‘<samp>Prev</samp>’, and ‘<samp>Up</samp>’ pointers, cross-references can point to any valid node. They are used to refer you to a place where more detailed information can be found on a particular subject. Here is a cross-reference which points to a node within the Texinfo documentation: See <a href="../texinfo/xref.html#xref">Writing an Xref</a> in <cite>the Texinfo Manual</cite>, for more information on creating your own texinfo cross references. </p> <hr> <div class="header"> <p> Next: <a href="Selecting-Xrefs.html" accesskey="n" rel="next">Selecting Xrefs</a>, Up: <a href="Xref-Commands.html" accesskey="u" rel="up">Xref Commands</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Index.html" title="Index" rel="index">Index</a>]</p> </div> </body> </html>
