Shortcut Your Most Used Phrases

If you find yourself typing the same things over and over, whether it’s a single Unicode character that doesn’t have a keyboard shortcut, or an entire phrase or chunk of text like an email signature, use the built-in Text Replacement feature in OS X.  

Go to the Text tab of the Keyboard pane of the System preferences and click the +. Put the shortcut you want in the left column and the text you want it to expand in the right.
