Cascades all open windows diagonally across the screen so you can see the title bar of each window. The active window always appears in the bottom right front with the rest of the windows behind it. The windows appear at close to full window size and stack down and to the right from the active window. The rest of the windows appear in the order they appear in the Window menu. You can view the title bars of several windows in this way. When you have more windows open than will fit in the view, then a second group of windows stacks on top of the first group.
