Well... not exactly.  :)

ctrl-B will take you to the definition corresponding to the declared
instance type, not necessarily the one you came from with "Find usages...".

ctrl-alt-B will give you a popup listing all known implementations of the
method under the cursor and ask you to choose one.  If there is only one
known implementation, it takes you directly there just as ctrl-B would.

That is to say... given:
class Foo { void blah() { /* thing 1 */ } }
class Bar extends Foo { void blah() { /* thing 2 */ } }

// ... somewhere else ...
Foo myFoo = new Bar();
myFoo.blah();

Pressing ctrl-B on myFoo.blah() will take you to the Foo definition, while
ctrl-alt-B will pop up "Choose implementation of *blah* (2 classes found)".
Guess which one I prefer.  ;)

Cheers,
