Revisions

Each time a document is edited a revision is created and represented in the Document History. Most often, revisions will be associated with an editing session when you have opened the document, edited it and then closed it. Revisions are a powerful way for you to keep track of older versions of your document.
 

Past revisions are always available to view.

• To access the Document History for the document you are currently working on, click Show History on the Document menu. 

You can also create a revision at any time you choose and roll a document back to an earlier revision.

To create a revision:

Revisions are created automatically whenever substantial change occurs to a document. You can also use the Create Revision option on the Document menu to explicitly create a revision of the document, allowing for the creation of multiple revisions of a document during one editing session.
 

Note:
In order for a revision to be created, changes must have been made since the last saved revision.
 

To roll a document back:

You can roll your document back to a past revision. This copies the revision to the top of the history listing, leaving all other histories intact. Choose Rollback while in the Select Document History dialog or click Rollback on the Main toolbar while viewing an older revision.
