<p>Cross-references have two major parts: the first part is called the
<em>label</em>; it is the name that you can use to refer to the cross
reference, and the second is the <em>target</em>; it is the full name of
the node that the cross-reference points to.
</p>
<p>The target is separated from the label by a colon ‘<samp>:</samp>’; first the
label appears, and then the target. 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 data-manual="texinfo" 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.
