How to add an empty line in the info tips?

I have plenty of items in my info tips for the images group. Now i have added ratings as the last item, but would rather like to have it separately at the bottom, for optical reasons. Is there a way to insert some empty line?

Enter a line with just a blank.

Thanks, that worked. I have previously tried to enter an empty line, which had no effect, but adding that space character did the trick. It looks much better now.
