title: Vim: \n vs. \r
body: <p>I haven't used vim in a Unix system in a while, but as I recall there was no \r, it was always \n.</p>
  
  <p>I'm using gVim under windows and when I <i>search</i> for new line characters I use \n. Searching for \r returns nothing. But when I <i>replace</i> the characters I have to use \r's. \n's give me ^@</p>
  
  <p>Can anyone explain what's going on here?</p>
