title: insert line break instead of <p> in TinyMCE
body: <p>I have initialised TinyMCE as follows. I want to force line breaks when user presses enter and not  the paragraphs. I'm trying following, but not working. I'm using TinyMCE version 3_3_8. </p>
  
  <pre><code>tinyMCE.init({
          mode: "exact",
          theme: "advanced",
          elements: "textAreaId",
          cleanup: false,
          theme_advanced_toolbar_location: "",
          theme_advanced_buttons1: "",
          theme_advanced_buttons2: "",
          theme_advanced_buttons3: "",
          height: 200,
          width: 300,
      forced_root_block : false,
      force_br_newlines : true,
      force_p_newlines : false,
          oninit: InitPosition
      }); //init ends
  </code></pre>
  
  <p>I tried to define <code>forced_root_block : ""</code>, but still it is not working. </p>
  
  <p>What am I doing wrong?</p>
