Let’s say you’re reading an article online, and you read a sentence that you want to email to a friend. Don’t do the copy-and-paste thing. Instead, just highlight the text and drag-and-drop it right on the Mail icon in the Dock. It will open Mail and put that sentence into a new mail message. This tip also works in other Cocoa applications like TextEdit, Stickies, and Safari. For example, if you’re reading a story and want to do a Google search on something you’ve read, just highlight the text and drag-and-drop it on the Safari icon in the Dock. It will launch Safari and display the Google Search Results.
