Basically on the top view of a car with a manual sunroof you'll see the stoppers on top of the glass, those aren't there in the electric one.
There's no handle for opening and the button for opening/closing is just like the one for the reading/interior light.
The first opening is a very acute angle, much like the one of the manual sunroof.
The second opening slides the sunroof back until there's about 1/4 of it left showing and the other 3/4s are above the roof.
There is also a sunblind below the sunroof which you can open/close manually and with it closed it gives the impression of no sunroof even being there when you're driving along.
I'd get pics but I've lost my usb cable
