Hotkeys demo

Try pressing up/down/left/right/del. The buttons below enable/disable the hotkeys (useful if you have another component on the page that may use keyboard navigation). You can attach the enable command to the onfocus event if you will - that way if the user clicks anywhere inside the tree container shortcuts will start working.

$(function () { 
    $("#demo_1").tree({
        // select a node initially so that you can start pounding up/down/left/right right away :)
        selected : "phtml_1",
        plugins : { 
            hotkeys : {
                functions : {
                    // lets add our own
                    "s" : function () {
                        alert($.tree.focused().container.attr("id"));
                    }
                }
            }
        }
    });
});
