Wouldn't that be super useful? Not only with email, but website URLs too. For example, you would choose "website", point your camera to a printed page with a URL in it and it would automatically copy to the clipboard the website it parses. Other thigns might include address, street names, phone numbers, sequence of more than 5 numbers on the same line etc. I had this idea after seeing a long URL for a video with assembly instructions for a product I bought, and thinking how long it'll take for me to type all of that.
