Emailing a link!
The way this tip work might be similar to the one I posted yesterday, but it is so neat. I know there are features in Safari's menus and a keyboard shortcut to do so, but it is so great to do it this way. To email a url that is loaded in Safari with Mail, you simply have to drag the small icon at the left of the url and while holding on to it, pressing "Command-Tab" and dropping the url on Mail. Mail will automatically create a new email with the url.
