Control+click on an item navigates to its definition, based on what kind of item is clicked. Control+clicking a variable will take you to the variable defintion; on a type to the type definition, etc.
How about "Control+Shift+Click" as a shortcut on a variable to go directly to the type declaration?
I find myself want to go from member variables directly to the class def.
Alt-LClick goes to Declaration
Alt-RClick opens "Navigate from Here"
Alt-Shift-LClick undecided - either Go to derived or Go to type
