Navigation controls and keyboad navigation

This example is the same as example 2, except for the navigation controls that have been activated. The navigation controls are described below.

Keyboard shortcuts:
Up arrow
Down arrow
Left arrow
Right arrow
Page up
Page down
Move up
Move down
Move left
Move right
Zoom in
Zoom out
Zoom extent

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. To correctly display the navigation icons, the vis.css file must be included. The user is free to alter or overload the CSS classes but without them the navigation icons are not visible.
