title: Is there an operation Step Back in NetBeans during debug process?
body: <p>In NetBeans when you insert <em>Breakpoint</em> and <em>Debug project</em>, it runs code until the <em>Breakpoint</em> and stop right in a line where we put <em>Breakpoint</em>. And afterwards we can execute our code step by step. If we Press <kbd>F8</kbd> which is <em>Step Over</em> operation, NetBeans executes next line. Sometimes we want to go back to the previous executed line because we want to change that line and see how it will work. <br>
  So, the question is how can I say NetBeans to <strong>Step Back</strong> (if we can call this like this), so instead of executing next line code it executes previous line code? I remember in Visual Basic 6.0 (now I don't know because don' t use it anymore) we could manage current execution line, i.e. we could just drag and drop debug pointer to the line we want during the debugging and it would start to execute code right from the place we put it. Is it possible in NetBeans?<br></p>

  I use NetBeans for debugging PHP application. PHP uses <code>php_xdebug-2.1.0RC1-5.3-vc9-nts.dll</code>  to to debug PHP code.</p>
