title: Powerpoint global button
body: <p>I think it's a simple question for anybody with some VBA skills oder PowerPoint-pro's:</p>
  
  <p>I have a presentation like a quiz, and I like to offer three jokers like in WWTBAM.
  So I created three buttons and i made the 50:50 button, that on click an animation starts so, that to wrong answers are hidden. So I now just want to, that if you clicked the joker-button on one slide, it have to be removed / disabled / crossed on ALL other following slides.</p>
  
  <p>Is there anybody who can show me a simple snippet which will do that?</p>
  
  <p>That would be really great.
  Thanks!</p>
