How to disable the "go to definition" on pressing CTRL key in Visual Studio?
This setting has no effect when the "Ctrl+Click Go To Definition" Extension from Microsoft Marketplace is installed. The setting specified on the extension documentation page wasn't visible in the Options, Productivity Power Tools, Other Extensions, and hence, masked the real problem. Uninstalling the extension allows reverting to classic Ctrl+Click select behavior.
Tools->Options->Text Editor->General
Uncheck Enable mouse click to perform Go to definition
It will work
