New page or new window!

I just discovered a few days ago that an awesome shortcut that I have always been using in Safari also works in the Finder. When I am on a webpage and I want to open a link in a new window, I just "Command-click" the link. The same shortcut also applies to the Finder, in any window, you can "Command-double click" on a folder to open it in a new window. This is very useful as I had to restart from the beginning in Macintosh HD to get a new window and start dragging files.
