title: Controlling PowerPoint Slideshow
body: <p>When a slideshow running in PowerPoint I want to control the movement (Next and Previous) of the slides. Of course it is possible with the <kbd>></kbd> and <kbd>&lt;</kbd> button on the keyboard, but is there any way in which I can have a custom application listening to the Next and Previous controls?</p>
  
  <p>My custom application has nothing but 2 buttons, next and previous, when I click either, the button's event handler should pass the control to the PowerPoint application running the slideshow. And thus, PowerPoint will move the slideshow back or forward?</p>
  
  <p>Somewhat similar to the way remote, wireless PowerPoint Presenters work on the s/w end.</p>
