ReSharper Web Help

This Navigate to command navigates from an argument in a method call to the the corresponding parameter in the declaration of the matching overload of this method.

If a symbol belongs to the current solution, ReSharper opens the corresponding file in the editor and places the caret at the symbol declaration. If a symbol is found in referenced libraries, ReSharper navigates according to the settings defined on the External Sources page of the Options dialog box. For more information, see External Sources.

The command becomes available when you invoke the Navigate To shortcut at a method call argument.
