Position the cursor on the class or reference to a class you want to
subclass and press Alt+Enter. An "Extend Class" intention appears, which
when invoked, allows you to specify name, visibility (default: public)
and destination package (default: the package from which you invoked
it). All fields and button are accessible via the keyboard for the
Easy subclassing by inner class:
Creating an inner subclass of another class is just as easy as creating
a regular subclass. Press Alt+Enter on a class or reference to a class
and invoke "Extend Class with Inner Class". The Extend Class dialog now
allows you to specify a destination class (using IDEA's familiar Class
Chooser dialog) and if the created class should be declared "static".
Highlight Usages in File for "import":
Invoking highlight (default CtrlShiftF7) usages on the "import"
keyword, will highlight all references to the class imported in the open
file. When the import statement is an "on demand" import, a chooser will
first popup, allowing you to choose which class to highlight or to
highlight all imported classes.
Highlight Usages in File for "extends" and "implements":
Easily highlight all implementing or overriding methods in the file by
invoking Highlight Usages in File on an "extends" or "implements"
keyword. If necessary a chooser will pop up where you can specify from
which class you want the implementing/overriding members highlighted
