While debugging, I am currently at this (next) statement :-
system()->executeFracture(calculateFracture(data));

Shift+Alt+F11 is the default global shortcut for "Step Into Specific", which will bring up a context menu of all the methods you can step into from the current instruction.
Of course, you can change the shortcut via Tools->Options->Customize...->Keyboard dialog.
Otherwise, there is no feature that allows you to step into the specific method under the editor caret. Sounds like a nice idea that you should put up on uservoice for Visual Studio.
