Blogger NavBar

From Bloggerhacks

The Blogger NavBar is a standard part of the Blogger template. It contains quick links to the Blogger main page, a search form for the specific blog you’re viewing as well as all blogs indexed by Google, the ability to flag content as objectionable, and a link to the Next Blog feature, which takes you to a randomly selected blog that might not be new to you. All blog readers can take advantage of the search and navigational links in the Blogger NavBar, not only those who have blogs, because the Blogger NavBar sits at the top of your blog waiting for someone to use it.
