title: Eclipse : How to restore default settings in perspectives?
body: <p>I have lost the "debug" panel/toolbar (with the yellow curly arrow step tools) in my Eclipse debug perspective and cannot get it back. </p>
  
  <p>Clicking the Window | Show View | Debug (beetle) seems to do nothing. </p>
  
  <p>How can I get it back, or restore the default settings (without altering anything else)?</p>
