title: How do I stop Emacs from changing my split buffers?
body: <p>I have a number of splits open, looking at various buffers. But when I for example check the help on a function it will replace one of the splits with the help buffer. Once I'm done reading the help I have to go back to the correct buffer manually which is a pain. How do I get Emacs to be nicer to my buffers?</p>
  
  <p><strong>Update:</strong> Help will let you press <code>q</code> to go back to the previous buffer. But causing the Emacs backtrace to pop up also steals one of my buffer windows <strike>and it doesn't have a <code>q</code></strike>.</p>
  
  <p><strong>Update:</strong> Backtrace DOES have <code>q</code> to go back. My original question still remains: how do I ask Emacs not to steal one of my splits?</p>
