title: What is the difference between :q and :qa! in Vim?
body: <p>I'm quite new to Vim so I first checked the help.txt file to inform myself about Vim. Here I saw the following:</p>
  
  <blockquote>
    <p>Close this window:  Use ":q".<br/>
       Get out of Vim:  Use ":qa!" (careful, all changes are lost!).</p>
  </blockquote>
  
  <p>The first one closes Vim. The second one also. Wouldn't all changes also go with :q? To be clear, I use the vim GUI not a command prompt.</p>
  
  <p>edit: It's more about the difference, not the actual meaning. The almost same explanation in the help.txt file confused me.</p>
