javascript:How to handle more keys at the sam time?
===

I am making a game with easel js and jquary.
I woud like to handle more pressed keys at the same time.
I have this bit of code for one key

    $(document).keydown(function(e){
    if (e.keyCode == 37) { 
       angle=angle+1;

    }
	if (e.keyCode == 40) { 
	   rad=angle*Math.PI/180;
       charachter.x=charachter.x-speed*Math.cos(rad);
	   charachter.y=charachter.y-speed*Math.sin(rad);
	   
	   stage.update();
    }
	if (e.keyCode == 39) { 
       angle=angle-1;
	   

    }
	if (e.keyCode == 38) { 
	   rad=angle*Math.PI/180;
       charachter.x=charachter.x+speed*Math.cos(rad);
	   charachter.y=charachter.y+speed*Math.sin(rad);
	   
	   stage.update();
    }
	
    });
But how do I make it so it is rotating and moving foward at the same time??
Ty for your answers and bye! Ras
