title: Shortcut key to expand the selected collapsed block/region in Visual Studio C#
body: <p>It is very frustrating to hold mouse just when my cursor is on the correct location but I can't expand the block.</p>
  
  <p>I use <kbd>
  Ctrl</kbd>+<kbd>M</kbd>
  , <kbd>
  Ctrl</kbd>+<kbd>O</kbd>
   to collapse to definition. But not able to expand one of the block after that. I have to hold the mouse and click on the plus sign.</p>
  
  <p>Thanks in advance.</p>
