If you have ever created links with target="_new" and wondered why all your pages were opening in the same window, even if was behind the current window, it is because "_new" is not actually a generic target. It is a window name, and by using it, you name the first window that comes up "_new".

Thereafter, every link that specifies target="_new" looks for and finds that window by name, and opens in it.

If you use target="_blank," a brand new window will be created each time, on top of the current window.
