- 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>

- <th>Keyboard shortcuts:</th>
- <td><div>Up arrow</div></td>

- <td><div>Left arrow</div></td>
- <td><div>Right arrow</div></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.
