States

You can set the instance to save the current state when the current selection is changed by using the saveState option.

You can use ctrl + z to undo a selection and ctrl + y to restore / redo an undone selection. The state() method can be used to manually save, load, undo, redo and clear states.

The instance will also fire it's own events corresponding to the state event. See the state events.

If you have defined a container with the containeroption, you must have the mouse pointer over the container for the keyboard controls to work. This prevents overriding the default keyboard controls for the webpage.
