    10 <p>The principal uses of the Navi pane are to display information about the

    30 <entry><p>Tabs are used to view parallel data views alternatively. Arrow indicators

    31 are shown at both ends of the pane when there are further tabs to scroll in

    32 the corresponding direction. Each tab has either a graphic or a text (or both)

    33 as a label. The following tab layouts can be used: <ul>

    34 <li><p>Two tabs</p></li>

    35 <li> <p>Three tabs</p></li>

    36 <li><p>Four tabs</p></li>

    38 <li> <p>Three long tabs (stacked so that only one is fully visible at a time)</p></li>

    39 </ul>The currently active tab is highlighted.</p><p>More than four tabs can

    40 exist simultaneously. They can be scrolled horizontally. However, as a design

    41 guideline, the number of tabs should be kept small (the maximum of six tabs

    42 is recommended), and the number should not be dynamic. See <xref href="GUID-72DE3EB1-1AF5-4157-8B99-A1C7143DAD2C.dita"></xref> for

    43 a description of the effect of tabs on the navigation within an application.</p></entry>
