This is one of those obscure Microsoft Word tips that can save you quite a bit of time if you are working with multiple documents at one go. Working with more than one open Word document also introduces the risk that you might forget to save one of the documents. In the off-chance that you do, add this handy shortcut to quickly save all open Word documents together without going to each one separately. In Microsoft 2010…
Go to File –> Options. Select Quick Access Toolbar.
From the dropdown, choose Commands Note in the Ribbon, scroll down to select Save All, and click Add.
The Save All button is added to your Quick Access Toolbar and you can now save all open Word documents without navigating to each document individually.
In MS Word 2003, you could display the Save All option by pressing on the Shift key while clicking on the File menu. But Word 2007 and 2010, involves a more roundabout way.
