title: Keyboard shortcut for Visual c# block comment in Visual Studio 2015?
body: <p>I know there is keyboard shortcut for single line(//....) 
  commenting <kbd>Ctrl + K + C</kbd> and uncommenting <kbd>Ctrl + K + U</kbd> . </p>
  
  <p>My question is that, <strong>is there any default keyboard shortcut for block (/* ...... */) commenting and uncommenting? If yes how?</strong> </p>
  
  <p>And If there is no default block  commenting keyboard shortcut defined, So
  <strong>is there a way i could add my own keyboard shortcut for this? How do i do that?</strong></p>
  
  <p>I have found lot of questions regarding commenting, but haven't found spoken about block commenting anywhere. Any help is appreciated :)</p>
