Roadster: What's the silver circle in the boot lid?

[sad61t]

I was watching the Turkey TV ad and noticed a chrome control in the middle of the boot lid top. It's in the preview brochure too. Any idea what it does?

I'm assuming the one between the seats is for locking the hood down, and it looks (from the last few frames of the video) as if the spoiler position can be controlled from the switch bank above the rear-view mirror.
