Safari, New Tabs

I just started using Safari as my default browser and have imported my bookmarks from Chrome. Everything seems to be working fine except I'm wondering how I can set Safari so that when I click on a bookmark on my favorites toolbar, a new tab opens. Currently when I'm on a page, for instance my email or whatever, and I click on a bookmark on my favorites toolbar, it opens in place of whatever I was viewing. I'd like it to open in another tab. How do I do that? I can't find the answer and it's probably that I'm not wording my search correctly.

Thank you!
