title: PhpStorm take a step back in debugger
body: <p>This question has been asked before for other IDE's, but what about for PHPStorm? Is there a way to take a step back while debugging? </p>
  
  <p>Specifically after an exception is thrown, I'd like to easily take a step back. Or at least be able to see the call stack so I can quickly see where I need to set the breakpoint, because currently I just have to run again from the beginning and try to stop just before exception.</p>
