Line spacing

The default line spacing is double. I've looked around the menu, start guide, etc. and can't find out how to change it, did alt and looked there and nothing. Though in screen shots online there's single spacing. How do I change the line spacing?!

As such, I don't think there is an option for changing the line spacing at least in the editor itself. You can do so by changing the CSS in the generated .html file.
