In the Fast Open dialog, there is a checkbox labelled "Show Inner Classes". In
fact it finds all nested classes, both inner (nonstatic) and static, so it
should read "Show Nested Classes" instead, or perhaps "Show Member Classes". The
exact terminology is given in the JLS:

http://java.sun.com/docs/books/jls/second_edition/html/classes.doc.html

"A nested class is any class whose declaration occurs within the body of another
class or interface."

"...all classes-top level and nested (including member classes, local classes
and anonymous classes)."

"An inner class is a nested class that is not explicitly or implicitly declared
static."

"Inner classes include local, anonymous and non-static member classes."
