I recently discovered a great application that is saving me a ton of time. This is called TextExpander, from SmileOnMyMac.
I discovered this application after watching MacBreak Episode 63, which has Merlin Mann covering TextExpander.
Merlin has also posted a new blog item about using TextExpander to help with Amazon associate information in Blogs.
Be sure to check these links out and give TextExpander a try, if you are lucky enough to own a Mac that is!
