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.
To choose Object-level or document-level undo options, do the following:
Note that, 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 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, Animate supports 100 levels of undo for the Undo menu command. Select the number of undo and redo levels, from 2 to 300, in Animate Preferences.
By default, when you undo a step by 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 in order to be able to restore the items with a Redo command.
The History panel (Window > 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.
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.
By default, Animate supports 100 levels of undo for the History panel. Select the number of undo and redo levels, from 2 to 300, in Animate 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.
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.
Scrolling to a step (and selecting the subsequent steps) is different from selecting an individual step. To scroll to a step, click to the left of the step.
When you replay steps with the History panel, the steps that play are the steps that are selected (highlighted) in the History panel, not necessarily the step currently indicated by the slider.
Apply steps in the History panel to any selected object in the document.
Drag from one step to another. (Don’t drag the slider; drag from the text label of one step to the text label of another step.)
Select the first step, then Shift-click the last step; or select the last step and Shift-click the first step.
