title: Ctrl + Dot (ShowSmartTag) not working in Visual Studio 2012
body: <p>I'm now using the Visual&nbsp;Studio&nbsp;2012, and now the keyboard shortcut for "ShowSmartTag", <kbd>Ctrl</kbd> + <kbd>.</kbd>, is not working. I googled a bit found someone said that <a href="https://en.wikipedia.org/wiki/CodeRush" rel="nofollow">CodeRush's</a> Quick Nav shortcut is the same, so I disabled that command in CodeRush, but still I can not fix this. I also tried to disable all those suspicious extensions, but still no success. Any idea?</p>
