<h1>Navigation Tree</h1>

<p>The navigation tree is shown in the left sub window of the system
editor. It is used for accessing the various components of a system
description. A node in the tree can be double clicked to view (or
hide) the sub tree of the node.</p>

<p>The root of the navigation tree is named "Project" if the system is
unnamed, otherwise the name of the system (i.e. the name of the
.xml-file).</p>

<p>Each process template of the system description is represented by a
node placed under the root of the navigation tree. When this node is
selected (i.e. clicked) the automaton becomes available for editing in
the right sub window of the system editor. Each template has a sub
node named "Declarations" that is used for typing in local <a
href="@System Descriptions/Declarations">declarations</a> and
documentation comments.</p>

<p>The remaining three sub nodes of the root are: <a href=
"@System Descriptions/Declarations">"Global declarations"</a>, <a
href="@System Descriptions/Process Assignments">"Process
assignments"</a>, and <a href=
"@System Descriptions/System Definition">"System definition"</a>.</p>

<p><b>Note:</b> the navigation tree can be opened in a separate window
using the "Drag out" button. The window returns to its original
position when it is closed.  <!-- (i.e. by pressing the <img border=0
src="@System Editor/close-button.gif" alt="[x]"> button in MS
Windows).  --></p>
