There are several ways to create new documents, open existing documents, and save documents in Word:
Each method will show the Open dialog box. Choose the file and click the Open button.
To rename a Word document while using the program, select File|Open and find the file you want to rename. Right-click on the document name with the mouse and select Rename from the shortcut menu. Type the new name for the file and press the ENTER key.
Several documents can be opened simultaneously if you are typing or editing multiple documents at once. All open documents are listed under the Window menu as shown below.
The current document has a checkmark beside the file name. Select another name to view another open document or click the button on the Windows taskbar at the bottom of the screen.
