Use is simple, and powerful Ctrl+Shift+V to paste with soft returns, Ctrl+ALT+V to paste with paragraph returns, and Ctrl+Shift+C to copy only the parent level items you select, it's that easy to use. If you try Ecco Pro, and give it a chance, it will become a central tool in your life. The value that eccoMAGIC then gives you, is substantial, and something you'll be using, and thankful for every day.
