Lately my F12 key does not seem to be working as expected in Visual Studio 2010 Professional SP1. It should go to the definition of what is selected, but instead it\'s performin
Maybe there is more than one definition for the class or function in your project?
I had this problem after copy/pasting a class definition. After pressing F12 on the class name, it first brought up a search result showing both files in which the class name was found. If you press F12 another time, it will jump to the first one in the search results.
Did you know that you can use Ctrl + - (Minus) to jump back? :-)
