To use the feature, load up Gmail, click Settings, and then click the Gmail Labs tab. Scroll down until you find "Create a document" and enable it. Click Save Changes at the bottom and you're good to go: When viewing a message, you'll see the new option on the right side of page.
Boy, Google Labs just keeps cranking out the nifty new features, huh? It was just last week that we learned how to send text messages from Gmail, and a couple months back we got the option to add your Google Calendar to Gmail. That's what I love about Gmail: It's already awesome, but Google keeps making it awesomer. (Yeah, it's a word! Go look it up.) [via The Official Gmail Blog]
