No, I believe he means the post text editor. When you create/edit a post, switch from Visual to Text mode and insert the <hr> tag after the body text of your post. You can see how it works here.

It worked, thanks!

Sorry for the noob question, but where exactly to put the code? After installing WP-Insert plugin, I’ve placed the code in Manage In-Post Ads/Ad-Below Post Content and it does shows under every post, which is not the desired effect. How do I make it slide from the lower right corner to the left, as it does on Viral Nova site?
