How to open all links in a new window?

Watch the video tutorial.

If you want to open all your links in a new window here is how to do it. But I don't recommend this hack. All your links - older post, newer post, home and all in-post links will open in a new window. This can be really annoying at times. As a thumb rule you should open external links in a new window and internal links in the same window. Anyways if anyone of you find this thing useful do tell me.
