To undo the last operation you performed in a document, choose Edit > Undo, just as you would do in any other application. (The name of the Undo command changes in the Edit menu to reflect the last operation you performed.) To undo more than one step at once, use the History palette. See About the History palette.
To open the History palette:
Choose Window > History.
To undo the last step:
Drag the History palette thumb up one step in the list. This has the same effect as choosing Edit > Undo.
The undone step turns gray.
To undo multiple steps at once, do one of the following:
|
Drag the thumb to point to any step. |
|
Click to the left of a step; the thumb scrolls automatically to that step. |
Note: To auto-scroll to a particular step, you must click to the left of the step; clicking the step itself selects the step. Selecting a step is different from going back to that step in your undo history.
As with undoing a single step, if you undo a series of steps and then do something new in the document, you can no longer redo the undone steps; they disappear from the History palette.
The History palette also allows you to repeat steps that appear in your step history, and to automate tasks based on steps you've performed. See Automating tasks.
