title: Is there anyway to hide/show all blocks of comments?
body: <p>[I've added c++ as a tag, but I'm not sure if I should... feel free to remove the tag if you don't deem it relevant.]</p>
  
  <p>I have to work with .hpp/*.cpp with so much comments, no one bothers to read them.</p>
  
  <p>To increase readability, I would like a way in emacs to just toggle hiding all blocks of comments, but not hide the code.</p>
  
  <p>Perusing through the manual, there is a way to toggle hiding blocks of comments when hiding blocks of code.  But there doesn't appear to be a way to do what I wish.</p>
  
  <p>Or is there?</p>
  
  <p>thanks.</p>
