The taskbar at the bottom of your screen contains a button for each Word document that is open. Click the taskbar button for the document that you want to switch to.
Word brings that document to the top.
INTRODUCTION
It's quite common to want to work on more than one Word document at the same time. When you have multiple documents open, they stack on top of each other much like a sheets of paper, with the document you are currently working on at the "top" of the stack. It only takes a couple of clicks to bring another document to the top. Word gives you more than one way to do this. Try the methods introduced in this task and then use the one you like the best.
TIP
One Word Taskbar Button
If you would prefer not to see a separate taskbar button for each Word document you have open (see step 1), open the Tools menu and choose Options . Click the View tab, clear the Windows in Taskbar check box, and click OK .
Alternatively, click Window in the menu bar.
The Window menu opens. At the bottom of the menu is a list of all your open documents; the current document has a check mark next to it.
Click the document that you want switch to. Word displays the document for you.
TIP
Using the Keyboard
The keyboard shortcut for switching among open Word documents is Ctrl+F6 . Each time you press Ctrl+F6, Word brings another open document to the top.
TIP
What Happens When the Taskbar Gets Too Crowded
Depending on your display settings and the number of Word documents you have open, Windows may decide that you don't have enough room to display a separate taskbar button for each document. When this happens, it displays only one Word taskbar button that contains a number indicating the number of open documents. When you click the button, a list of all the open documents pops up. To switch to one of the documents, simply click it in the list.
