In Word 2010, you can pin documents you need to access often to make finding them nearly effortless.
Within the Backstage view is the Recent Documents list.
To access the Recent Documents list:
Here you will see a list of recently accessed documents. This list changes based on the different files that you open and work with, and by default, the list is generated automatically by Word.
If you have a document you work with often, you can "pin" it to the list. This way, it will always appear in the Recent Documents list.
To pin a document to the Recent Documents list, just click the pin icon next to the document you wish to keep in the list.
Notice that the pin changes to a push pin.
If you decide you no longer want the document to appear in the Recent Documents list, simply click the push pin icon to remove it.
