If you’ve enabled the status bar option under the View menu in Safari, you can see the link target as you mouse over a link.
If a link will open in a new window, the status bar says:
Open “http://www.domain.com/” in a new window.Also, if you’re holding down the Option key it changes to:
Download “http://www.domain.com/”The Command key forces the link to open in a new window, and so the status bar displays:
Open “http://www.domain.com/” in a new window.Hold down the Control key and the status display again changes to:
Display a menu for “http://www.domain.com/”
