You can go to the account URL by choosing the Go to URL command from the Edit menu. As a shortcut, you can also Option-click in the URL field. Your web browser, e-mail, or other Internet application will be launched to process the URL. If the URL does not contain a protocol (like http: or mailto:), a web address is assumed unless there is an '@' character in the URL. If an '@' character is present, the URL is processed as an e-mail address.

The application used to process the URL address is determined by the settings in the Safari and Mail application preferences.
