how do i make links open in a new tab

Hi There,

Can someone please tell me how to get iWeb to set pages to open on a new tab when links are clicked.

Like when someone is viewing my website, I want the links in that website to open in a new tab within the web-browser when someone clicks on them. I know I can make links open in a New window but how do I make them open in a new tab.

Thanks a bunch

Jason
