You can rename any document from the Library. From the Outline Editor, you can rename a module, section, or topic document only.
Document names do not have to be unique. Since documents are identified by their ID, two documents with the same name can exist in the same Library folder or outline.
Note: You can also rename a document using the Name property in the Properties toolpane (General category). However, you cannot rename multiple documents at the same time using this toolpane.
Multi-user Considerations
Before you can perform this action, you must check out the document. After you save any changes, you should check in the document to make it available to other authors and add the changes to the Developer's version control system.
The Developer preserves the name of versioned documents. When you roll back a renamed document to a previous version, the document name rolls back as well.
To rename a document:
Click the document that you want to rename.
On the Edit menu, choose Rename.
After selecting a document, you can also click the document name or press F2 to start edit mode.
You can also right-click a document and choose Rename.
Type a document name.
Press ENTER or click anywhere outside the name to save your changes.
