title: What are all the possible settings attributes in TinyMCE's addButton() function?
body: <p>The <a href="http://www.tinymce.com/wiki.php/API3:method.tinymce.Editor.addButton" rel="noreferrer">documentation</a> is not very clear on this.</p>
  <blockquote>
  <p>name - String - Button name to add.</p>
  <p>settings - Object - Settings object with title, cmd <strong>etc</strong>.</p>
  </blockquote>
  <p>&quot;etc&quot;? Really? Where can I see the rest of the possible attributes?</p>
