We all have a few large chunks of text we have to type regularly–like your address, long names or phrases, or even tables and images you use often. The AutoText feature in Word allows you to store these chunks of text and quickly insert them with a few keystrokes, so you can waste less time typing.
The AutoText feature has been part of Office for a long time, but is now part of Quick Parts, which was added to Office 2007. In addition to AutoText entries, the Quick Parts feature allows you to insert document properties (such as title and author) and fields (such as dates and page numbers). Quick Parts and AutoText entries are also known as “Building Blocks” and Word comes with many predefined building blocks. You can also add as many custom building blocks as you want.
