title: How to copy to clipboard in Emacs Lisp
body: <p>I want to copy a string to the clipboard (not a region of any particular buffer, just a plain string).  It would be nice if it were also added to the kill-ring.  Here's an example:</p>
  
  <pre class="lang-lisp prettyprint-override"><code>(copy-to-clipboard "Hello World")
  </code></pre>
  
  <p>Does this function exist?  If so, what is it called and how did you find it?  Is there also a <code>paste-from-clipboard</code> function?</p>
  
  <p>I can't seem to find this stuff in the Lisp Reference Manual, so please tell me how you found it.</p>
