Av8, the way to start the modes is by shooting the white arrows, once they have been completed all the white arrows will flash, the next shot you make will be 2x'd until you lose that ball. By shooting the left or the right orbit you will start the mode that is lit down the bottom of the playfield. In terms of modes its like TZ, you just have to start them, you dont have to complete them, so potentially if you were trying to make it to super hero you can time the modes out.
