For interfaces with one implementation how can I just directly go to that implementation?

I often have to debug Java code which was written so that there is an interface and exactly one implementation of that interface. For instance there would be an interface Foo with exactly one implementation called `FooImpl`. In the following code if I Ctrl-click on `doThings` it'll jump to `Foo.java` when I actually want to go to `FooImpl.java` to see the implementation. ``` public void doStuff(Foo foo) { foo.doThings(); } ``` When I end up at the interface I have to use Ctrl-Shift-R to open up `FooImpl`. It'd be really nice if I could do something lick Ctrl-Alt-click on `doThings` and end up inside `FooImpl.java`. If there are multiple implementations in the workspace then perhaps it would just pop up a box telling me what they are. Is there a plugin or existing function in eclipse that does this? I know that I could go to `Foo.java` and then get the hierarchy and go to the implementation, but that's more clicks than are necessary when there is exactly one implementation of an interface.
