Undoing changes

The changes that you make to a document can be reversed one step at a time, or reversed all the way to the state when the file was last saved. You can set the number of undo levels in the Options dialog box (see Memory and Undo options).

• To reverse the last change to a file, click Undo on the Edit menu, or press CTRL+Z.
• To reverse the last Undo action, click Redo on the Edit menu, or press CTRL+SHIFT+Z.
• To return the document to the state when the file was last saved, click Revert on the File menu.

Both the Undo and Redo features in the Edit menu also include a description of what action will be affected. For example, after you move an object, the Edit menu displays Undo Translate.
