Indicates if sidebar should listen to keyboard.
Boolean, default = true
If .keyboard property is set to true, the sidebar will add event listener to listen for keyboard events. There are several keyboard keys linked to the sidebar actions:

- Arrow up - previous node
- Arrow down - next node
- Arrow right - expand node
- Arrow left - collapse node

This property can be defined during object creation: $('#sidebar').w2sidebar({ name : 'sidebar', keyboard : false, nodes : [ { id: 'id-1', text: 'Level 1', hidden: true }, { id: 'id-2', text: 'Level 2', expanded: true, nodes: [ { id: 'id-2-1', text: 'Level 2.1' }, { id: 'id-2-2', text: 'Level 2.2' } ]}, { id: 'id-3', text: 'Level 3' } ] }); Or any time after the sidebar has been created: w2ui['sidebar'].keyboard = true; Internally, the feature is implemented by w2utils.keyboard object. If there more then one sidebar on the screen and all of them have .keyboard set to true, then the last sidebar where user selects a record will active keyboard listener.
