To get a link or URL, you specified or referred in your blogs, to be opened in a separate New Browser Window, what you need to do is add the target="_blank" attribute to your link tag i.e. in in the HTML code.
<a href="http://sabdarsyed.blogspot.com/" target="_blank"> This is My BlogSpot!</a>
This will give you the following link:
This is My BlogSpot!
This is useful when you do not want to open a link, you specified or referred in your blog, to open in the same window, rather it should open in a new browser window, by keeping original post open.
