<h2 class="chapter">6 Nodes</h2>

<p><em>Nodes</em> are the primary segments of a Texinfo file.  They do not
in and of themselves impose a hierarchical or any other kind of
structure on a file.  Nodes contain <em>node pointers</em> that name
other nodes, and can contain <em>menus</em> which are lists of nodes.  In
Info, the movement commands can carry you to a pointed-to node or to a
node listed in a menu.
</p>
<p>Node pointers and menus provide structure for Info files just as
chapters, sections, subsections, and the like provide structure for
printed books.  The two structures are theoretically distinct.  In
practice, however, the tree structure of printed books is essentially
always used for the node and menu structure also, as this leads to a
document which is easiest to follow.  See <a href="Texinfo-Document-Structure.html#Texinfo-Document-Structure">Texinfo Document Structure</a>.
</p>
<p>Because node names are used in cross references, it is not desirable
to casually change them once published.  Such name changes invalidate
references from other manuals, from mail archives, and so on.
