Permanently remove items deleted with Undo
By default, when you undo a step using Edit > Undo or the History panel, the file size of the document does not
change, even if you delete an item in the document. For example, if you import a video file into a document, and
undo the import, the file size of the document still includes the size of the video file. Any items that you delete from
a document when performing an Undo command are preserved to restore the items with a Redo command. To
permanently remove the deleted items from the document, and reduce the document file size, select File > Save And
Compact.
Using the History panel
The History panel (Window > Other Panels > History) shows a list of the steps you've performed in the active
document since you created or opened that document, up to a specified maximum number of steps. (The History
panel doesn't show steps you've performed in other documents.) The slider in the History panel initially points to
the last step that you performed.
To undo or redo individual steps or multiple steps at once, use the History panel. Apply steps from the History panel
to the same object or to a different object in the document. However, you cannot rearrange the order of steps in the
History panel. The History panel is a record of steps in the order in which they are performed.
Note: If you undo a step or a series of steps and then do something new in the document, you can no longer redo the steps
in the History panel; they disappear from the panel.
To remove deleted items from a document after you undo a step in the History panel, use the Save And Compact
command.
By default, Flash supports 100 levels of undo for the History panel. Select the number of undo and redo levels, from
2 to 9999, in Flash Preferences.
To erase the history list for the current document, clear the History panel. After clearing the history list, you cannot
undo the steps that are cleared. Clearing the history list does not undo steps; it removes the record of those steps from
the current document's memory.
Closing a document clears its history. To use steps from a document after that document is closed, copy the steps
with the Copy Steps command or save the steps as a command.

Undo steps with the History panel
When you undo a step, the step is dimmed in the History panel.
• To undo the last step performed, drag the History panel slider up one step in the list.
• To undo multiple steps at once, drag the slider to point to any step, or click to the left of a step along the path of
the slider. The slider scrolls automatically to that step, undoing all subsequent steps as it scrolls.
