+<p>The UI (User Interface) in devices based on the Symbian platform consists
+of at least one display for showing output to mobile device users and keys
+that allow mobile device users to enter input. The number, size, and resolution
+of displays varies among <xref href="http://www.forum.nokia.com/devices/matrix_s60_1.html" scope="external">legacy
+S60 devices and devices based on the Symbian platform</xref>, as do the
+keys available for input.</p>
+<fig id="GUID-84A0AF11-85F9-45E1-B723-47A696C42619"><title>Symbian UI</title><image href="GUID-CA7B2B53-B0DD-4830-90CF-15FD101C66F1_d0e45876_href.png"/></fig>
+<p>The display consists of the following elements:</p>
+<ul>
+<li><p><b>Window</b> - An area on the display. There are windows
+that take up the entire display, and other windows that only take up part
+of the display. For example, pop-up windows do not cover the entire display.
+Pop-up windows have frames and typically the underlying window is partly visible
+behind the pop-up window. Access to windows is gained through <xref href="GUID-5944FFF1-79C6-4F5E-95C8-F4833AFC64AB.dita"><i>controls</i></xref>.</p>
+</li>
+<li><p><b>Pane</b> - This is a sub-element of a window that is dedicated
+to a specific purpose. Windows may contain several panes, and panes may contain
+sub-panes. </p></li>
+</ul>
+<section id="GUID-4D941E4F-5954-4132-AAB4-CD4A725862EE"><title>Windows</title>
+<p>The following figure illustrates a typical window for an application:</p>
+<fig id="GUID-4707694E-3017-4CD2-A5EC-63B3C624C6DF"><title>Symbian UI window</title><image href="GUID-72262200-B940-4D0C-8FA0-6628E9894E8F_d0e45911_href.png"/></fig>
+<p>Typically, a window contains a status pane, a main pane, and a control
+pane.</p>
+<note>
+<p>Symbian UI can rotate between portrait and landscape layouts. For more
+information on the design implications of this feature, see <xref href="GUID-685C3F33-1530-4984-B125-E4EF8EBB2EE8.dita">Symbian
+UI with rotation</xref>.</p>
+</note>
+<p>By default, the <i>status</i> pane:</p>
+<ul>
+<li><p>occupies the top part of the display</p></li>
+<li><p>shows information on the current application and state, and
+general information about the device status, such as signal and battery strength</p>
+</li>
+<li><p>contains five sub-panes: <i>title pane</i>, <i>context pane</i>, <i>navi
+pane</i>, <i>signal pane</i>, and <i>battery pane/universal indicator pane</i></p>
+</li>
+</ul>
+<p>The <i>main</i> pane is in the middle of the display. Applications display
+their application state in the main pane.</p>
+<p>By default, the <i>control</i> pane:</p>
+<ul>
+<li><p>occupies the bottom part of the display</p></li>
+<li><p>displays the labels associated with the two softkeys</p>
+</li>
+<li><p>appears even when pop-up windows are on the display, although
+they are not contained in the pop-up window.</p></li>
+</ul>
+<p>Mobile device users navigate through applications based on input from
+selections in the <i>control pane</i> or key presses. The traditional hierarchical
+tree structure forms the basis for navigation, with mobile device users moving
+from one node, which represents a state, to another. </p>
+<p>The figure below illustrates an example of a basic state hierarchy.</p>

+<section id="GUID-1ADE27AA-CFB6-42C2-8AE2-E7EDD4EC627A"><title>Tabs</title>
+<p>The Symbian UI supports tabs, which allow you to collect information
+for a state onto different pages. These tabs exist in the same node of the
+navigation hierarchy. The concept of tabs is related to the term <xref href="GUID-DAC32BB9-C0EB-42FF-A596-C2F1A90A4BD7.dita"><i>view</i></xref>.</p>
+<p>The following figure illustrates the use of tabs in an application.</p>

+hierarchy.</p>
