When you start Word, a new blank document appears. The Undo button is on the Mini toolbar. The File tab is used to save and print files. The Zoom slider is not located in backstage view in the Info command. You can hide the Ribbon by double-clicking the active tab. Saving a document in PDF format will not allow users to edit the document. You can close a document using keyboard shortcuts and KeyTips. The Help command can be accessed in dialog boxes.
