You read your code and bump into a method that you'd like to dive into. You then, most probably, hit F3 (find it's declaration) or attempt to drill down using CTRL + LEFT-MOUSE-CLICK. However, then you end up with a declaration of the method's signature in an interface. What you'd like to find are the implementations of that method. Fear not! Instead of ending up at the signature in the interface press CTRL + T which will popup the implementations with shortcuts to the actual implementations' code.
