Intellisense “Toggle Completion Mode” doesn't work with C++ in Visual Studio 2010 Professional

Question

I am having problems with my \"Toggle Completion Mode\" under the Edit->Intellisense tab in Visual Studio 2010 Professional. The picture describes it quite well.

Answer 1

I know this was posted a long time ago but I figured I would offer my solution. I changed the shortcut to something that is not as annoying as ctrl + space. You can do this in Options -> Keyboard -> Edit.CompleteWord.

Hope this helps someone.
