title: Vim to copy first word in line and print it after that word separated by 4 spaces
body: <p>I'm using Vim and would like copy the first word in certain lines and simply paste it after that word separated by 4 spaces.  Below is an example.</p>
  
  <pre><code>football
  run
  phone
  watch
  </code></pre>
  
  <p>Would then become:</p>
  
  <pre><code>football    football
  run    run
  phone    phone
  watch    watch
  </code></pre>
  
  <p>I would only like to be applied to lines 186 to 1413.  I'm able to do this using Vim visual mode but there has to be a quicker way.</p>
