Pastebud—as the service is called—works using two bookmarks in Safari. One prepares and loads the page you are viewing, ready to select text at the touch of a finger. From there, you can copy any text you want and create a new mail message with that text in it. In addition to that, you will be able to copy and paste in the text field of a different web page.
