I have not found what I look for in Google and in the Plugins section at wordpress.org.
I'm looking for a plugin/function that allows me to create link to an existing post interactively when I'm editing a new post.
For exemple, I create a new post, I type the words "Hello world", I want that WordPress suggest me a list of existing posts (at least one post), to create a link to the post I choose (e.g: "Hello world"). After validate, WordPress could add a link like :
<a href="http://myblog.com/2013/02/Hello world" title="Hello world">Hello world</a>
Does someone know which plugin do that ?
