Why not put the rest of your lazy digits to work with this accessory that puts two programmable buttons on the rear of the DualShock 4 controller? > Called, imaginatively, the Back Button Attachment, the gadget plugs into the PS4’s accessory port and adds three interactive items to the back end of the controller. There are two paddle-style buttons that seem suited for middle fingers to hit easily, each of which can be programmed to be any of the ordinary buttons.
