anything equivalent to jwhich

Is there anything in idea 7.0.3 that's similar to jwhich? In particular, given a classname, like com.foo.Bar, I'd like to find the absolute pathname of
the .class file that implements it. If it comes from a jar file, then I want the jarfile and then the path. The idea command "quick documentation lookup" (Ctrl-Q) comes close, but doesn't always
show the particular jar.

If the class is actually available in multiple jars, I'd like to seem them all. This is useful if one name is overriding another.

Thanks.
