You can use the Window menu to open the History panel like any of the other panels in Flash; the History command appears on the Other Panels submenu. Each step you take in the active document during a work session appears on a separate line in the History panel. Steps you take in other Flash documents don't appear in other History panel lists. If you no longer need the steps in the History panel, you can erase the entire list. When you close a document, Flash clears the History panel.
