Activating the ROLL SEL switchlight on the side with the unjammed aileron provides which function?

Explanation:
When one aileron is jammed, you need an alternate way to control roll. The ROLL SEL switchlight on the side with the unjammed aileron enables the spoileron function for the pilot flying. In this mode, the unjammed aileron drives the spoiler panels to deflect differentially, producing a roll moment and preserving roll authority despite the jam. It isn’t about activating the whole primary flight surfaces, locking the aileron, or engaging the yaw damper.
