One button,multiple lights

Hello.
You can use the usual button, but you will have to register the commands in the script. For example, this:

var flag = 0;
IR.AddListener(IR.EVENT_ITEM_PRESS,IR.GetPage("Page 1").GetItem("Item 1"),function()
{ 
   flag++; 
    switch (flag){
      case 1:
         IR.GetPage("Page 1").GetItem("Item 2").Value = 1;
         break;
      case 2:
         IR.GetPage("Page 1").GetItem("Item 3").Value = 1;
         break;
      case 3:
         IR.GetPage("Page 1").GetItem("Item 4").Value = 1;
         break;
      case 4:
         IR.GetPage("Page 1").GetItem("Item 5").Value = 1;
         break;
      default:
         IR.GetPage("Page 1").GetItem("Item 2").Value = 0;
         IR.GetPage("Page 1").GetItem("Item 3").Value = 0;
         IR.GetPage("Page 1").GetItem("Item 4").Value = 0;
         IR.GetPage("Page 1").GetItem("Item 5").Value = 0;
         flag = 0;
      }
          
})

Thank you very much,but I don't know the js so good.
