Safari: Open typed URLs in new tab by default?

In FF, I take for granted that I have the TMP plugin (which rocks, BTW) and it has a setting to open typed URLs in new tabs.

Is there a way to make this the default behavior in Safari? I am well aware that I can hit command+enter. I'd rather just hit enter and have the URL open in a new tab. Basically, I'd like to reverse the behavior (Enter = new tab, Command+Enter = current tab).

Thanks in advance.
