title: Insert text before and after selection and set style of new text
body: <p>I can insert text before and after the selection using:</p>
  
  <pre><code>Selection.InsertBefore "start"
  Selection.InsertAfter "end"
  </code></pre>
  
  <p>But I have no control over the style of the inserted text. How can I set the new, inserted text to a specific style (and leave the original selected text as it is)?</p>
