title: Mark-up for bold and italic in emacs org-mode
body: <p>In emacs org-mode, we can use mark-ups to set <a href="http://orgmode.org/manual/Emphasis-and-monospace.html" rel="noreferrer">Emphasis and monospace</a>.<br>
  e.g.</p>
  
  <p>*<strong>bold*</strong></p>
  
  <p>/<em>italic</em>/</p>
  
  <p>
  How can we make a word both bold and italic?<br>
  It seems neither */.../* nor /*...*/ works.</p>
