Undo, redo, and history
Undo, Redo, and Repeat commands
To undo or redo actions on individual objects, or all objects within the current document, specify either object-level or document-level Undo and Redo commands (Edit > Undo or Edit Redo). The default behavior is document-level Undo and Redo.
You cannot undo some actions when using object-level Undo. Among these are entering and exiting Edit mode; selecting, editing, and moving library items; and creating, deleting, and moving scenes.
To remove deleted items from a document after using the Undo command, use the Save And Compact command.
To reapply a step to the same object or to a different object, use the Repeat command. For example, if you move a shape named shape_A, select Edit > Repeat to move the shape again, or select another shape, shape_B, and select Edit > Repeat to move the second shape by the same amount.
By default, Flash supports 100 levels of undo for the Undo menu command. Select the number of undo and redo levels, from 2 to 9999, in Flash Preferences.
Permanently remove items deleted with UndoBy 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.
