open in new window vs new tab

I'm afraid this is controlled in the user's browser preferences, and is not a feature of HTML. Links specify they want to open in a blank context, and the browser decides if that will be a new tab or window.

It is possible for JavaScript to attempt to force a new window, but this is such unexpected behavior that browsers block it and throw a toolbar alert asking a user to permit the site to open popups.

Now...it's been a few years since every browser make switched the default from Tab to Window, and very few people know they can go into their browser preferences to change it back, so perhaps I should change the default wording in the config to Tab instead of Window...
