-<h2>Navigation controls and keyboad navigation</h2>
-<div style="width: 800px; font-size:14px; text-align: justify;">
-  This example is the same as example 2, except for the navigation controls that have been activated. The navigation controls are described below. <br /><br />
-  <table class="legend_table">
-    <tr>
-      <th>Icons: </th>
-      <td><img src="../../../dist/img/network/upArrow.png" />     </td>

-    <tr>
-      <th>Keyboard shortcuts:</th>
-      <td><div>Up arrow</div></td>
-      <td><div>Down arrow</div></td>
-      <td><div>Left arrow</div></td>
-      <td><div>Right arrow</div></td>
-      <td><div>=<br />[<br />Page up</div></td>
-      <td><div>-<br />]<br />Page down</div></td>
-      <td><div>None</div></td>
-    </tr>
-    <tr>
-      <th>Description:</th>
-      <td>Move up</td>
-      <td>Move down</td>
-      <td>Move left</td>
-      <td>Move right</td>
-      <td>Zoom in</td>
-      <td>Zoom out</td>
-      <td>Zoom extent</td>
-    </tr>
-  </table>
-  <br />
-  Apart from clicking the icons, you can also navigate using the keyboard. The buttons are in table above.
-  Zoom Extends changes the zoom and position of the camera to encompass all visible nodes. <u>To correctly display the navigation icons, <b>vis.css</b> or <b>vis-network.min.css</b> must be included.</u>
-    The user is free to alter or overload the CSS classes but without them the navigation icons are not visible.
