AutoText
You can use AutoText to store text or graphics you plan to reuse, such as product names, boilerplate text, a company logo, or a formatted table. When you're ready to retrieve an item, select from a list of AutoText entries.
Word includes built-in AutoText entries (such as salutations and closings) that are available when you create letters. To create your own autotext entry select the text you want to reuse and choose Shift + F3. To retrieve the entry, type a few words and hit the F3 key.
To make your life easier, add the autotext entries to your toolbar. Right Click on any toolbar and choose customize. Choose Autotext on Commands tab. Click and drag the autotext entries to the toolbar for easy access.
Please remember that it's not an alternative to templates! If you send same type of letter, save it as a template by choosing File - Save as (File type - Template). Using this method you will find the letter very easily by going to File - New and choosing the right template.
