My friend and colleague, Reba Nance of the Colorado Bar, shared a well written tip with several of us. It illustrates how to quickly type and send an e-mail without ever leaving Microsoft Word. I was going to use it as a tip here, but another colleague, David Bilinsky, appropriated it to his blog first. As much as I hate to reward David's bad behavior, (that is beating me to the post, not using the tip–which we both had permission to do) I think I'll just link to his blog post on Composing an E-Mail Without Leaving MS Word.
All kidding aside, this is a simple and great tip for when you are working on documents in Word and need to send someone a quick e-mail without opening Outlook and running the risk of being distracted by your Inbox.
