Brett Terpstra has coded some remarkable TextExpander snippets including:

• the ability to auto hyphenate the clipboard
• encode e-mail addresses
• paste markdown referenced
• auto generate markdown references from your clipboard
• create lorum ipsum text using text from word lists from Dune, Foundation, Ringworld, Harry Potter, and Doctor Who.

There is a lot more. If you are a TextExpander nerd, go here and then here. Now go!
