title: Why Does VS 2010 'Comment' Keyboard Shortcut Change in C++?
body: <p>For me, Visual Studio's <kbd>Ctrl</kbd> + <kbd>K</kbd>, <kbd>Ctrl</kbd> + <kbd>C</kbd> keyboard shortcut is used to comment-out the selected lines. When editing C++, this sometimes uses block comments (<code>/* */</code>) and sometimes uses line comments (<code>//</code>). Why does it change? How does it decide which to use when?</p>
