<p>The principal uses of the Navi pane are to display information about the
current state and view, and to help the user to navigate in the application.</p>

<p>Depending on the context, the Navi pane contains elements presented in

<entry><p>Tabs are used to view parallel data views alternatively. Arrow indicators
are used only for navigation texts. </p><p>Each tab has either a graphic or
a text (or both) as a label. The following tab layouts can be used: <ul>
<li><p>Two tabs</p></li>
<li> <p>Three tabs</p></li>
<li><p>Four tabs</p></li>
<li><p>Two long tabs</p></li>
<li> <p>Three long tabs (stacked so that only one is fully visible at a time)</p></li>
</ul>The currently active tab is highlighted.</p><p>More than four tabs can
exist simultaneously. They can be scrolled horizontally. However, as a design
guideline, the number of tabs should be kept small (the maximum of six tabs
is recommended), and the number should not be dynamic. See <xref href="GUID-72DE3EB1-1AF5-4157-8B99-A1C7143DAD2C.dita"/> for
a description of the effect of tabs on the navigation within an application.</p></entry>
