As you work with documents in the various document editors, you may find it necessary to undo or redo the editing actions that you perform. Most document editors provide an Undo and Redo command on the Edit menu for just this purpose. For example, in the Outline Editor you can undo the linking of any document in the outline, undo the deletion of links, and so on. If you are working on a web page, you can undo the addition or editing of text, as well as any formatting commands that you perform. You can also redo actions in the same way. There is no limit to the number of actions you can undo/redo in most document editors.
Important Note: Undo/Redo is not available from the Library or the Package Editor. Also note that you cannot undo glossary term links that are created using the Update Glossary Links command.
