I didn't know about this and after sharing with some others who didn't know I thought I would pass it along to HN. This is a great way to read a story on HN and view the comments at the same time. You can click and drag a link to the other window to open it.
Very nice feature, I didn't know about it. Thanks a lot for sharing! Hands-down, my favorite feature in Windows 7 is the ability to drag a window to the screen edges for a similar effect.
