title: How to exit the Vim editor when :q or :x doesn't work
body: <p>Newbie to vi / vim, I normally use pico but using a locked down box (for now) that only has these 2 editors.</p>
  
  <p>I am having trouble getting it to save a file or even just quit. I see others having the same issue and they were told to use :x but even that doesn't work, just throws up an error message.</p>
  
  <p>Is there an exit command that JUST works?</p>
  
  <p>thanks</p>
