Here is my script thus far

window.addEvent("domready", function(){
		var maxLength    = 100;
		var counterFluid = 1;
		var wall = new Wall("wall", {
		                "draggable":true,
		                "autoposition":true,
		                "inertia":true,
		                "width":150,
		                "height":150,
		                "preload":true,
		                "rangex":[-6,6],
		                "rangey":[-6,6],
		                callOnUpdate: function(items){
		                    items.each(function(e, i){
		                        var a = new Element("img[src=/path/your/images/"+counterFluid+".jpg]");
		                            a.inject(e.node);
		                        counterFluid++;
		                        // Azzera counter
		                        if( counterFluid > maxLength ) counterFluid = 1;
		                    })
		                }
		            });
		// Init Fluid Wall
		wall.initWall();
		 
		// Behaviors
		$("mv-top").addEvent("click", function(e){
		    e.stop();
		    wall.moveTo(wall.getCoordinatesFromId(wall.getActiveItem()).c, -6);
		}.bind( this ))
		 
		$("mv-bottom").addEvent("click", function(e){
		    e.stop();
		    wall.moveTo(wall.getCoordinatesFromId(wall.getActiveItem()).c, 5);
		}.bind( this ))
		 
		$("mv-left").addEvent("click", function(e){
		    e.stop();
		    wall.moveTo(-6,wall.getCoordinatesFromId(wall.getActiveItem()).r);
		}.bind( this ))
		 
		$("mv-right").addEvent("click", function(e){
		   e.stop();
		   wall.moveTo(5,wall.getCoordinatesFromId(wall.getActiveItem()).r);            
		}.bind( this ))
		 
		$("mv-center").addEvent("click", function(e){
		   e.stop();
		   wall.moveTo(0,0);            
		}.bind( this ))
});

I would like to add keyboard navigation to this, but not having luck. A colleague suggests to use the snippet below, however I'm a bit confused on how to integrate it. Any help is greatly appreciated!


Suggested Keyboard Nav Script

if (event.key == 'up') {
			var cc = this.mywall.getCoordinatesFromId(this.mywall.getActiveItem());
			if( $$("a[rel=" + cc.c + "x" + ((cc.r)-1) + "]").length > 0 ){
	                    $$("a[rel=" + cc.c + "x" + ((cc.r)-1) + "]").fireEvent("click")	
				this.mywall.moveTo(cc.c , ((cc.r)-1) )
			}
                }
