How to Create Quick Parts in Outlook 2013 to Save Keystrokes
Drag your mouse over some text in an e-mail message to select it.
The text you select is highlighted.
Click the Insert tab and choose Quick Parts in the Text group of the Ribbon.
A drop-down menu appears.
Choose Save Selection to Quick Parts Gallery.
The Create New Building Block dialog box appears.
Type a new name for your Quick Part if you don't like the one you see.
The suggested name might be fine, but you may prefer something else. You can also assign a category and description to your Quick Part, but that makes very little difference in how you use it, so you can leave that alone.
After creating a Quick Part, you can make it appear in an e-mail body in a flash: Click Quick Parts in the Ribbon and click the Quick Part you want. It’s so easy, you’ll never want to send an original e-mail again.
