title: How do I increase the scrollback buffer in a running screen session?
body: <p>Lets say I have a currently running <a href="http://en.wikipedia.org/wiki/GNU_Screen">screen</a> session I am interacting with through putty.  I've realized that the scrollback buffer is too small and would like to increase it <em>without</em> starting a new screen session.</p>
  
  <p>Is there a way to do this?</p>
