One useful keyboard shortcut that allows us to quickly navigate within a large Java
ile is Ctrl+F12 . This keyboard shortcut will present an outline of the current Java file
in the editor and show all of its methods and member variables.
Typing in the text field labeled Filter narrows the list of member variables and
methods shown. This keyboard shortcut makes it very fast to navigate through
Hitting Alt+F12 will result in a pop up window outlining the class hierarchy of
the current Java class.
We can use the above shortcut to quickly navigate to a superclass or a subclass of
the current class.
Another useful keyboard shortcut is Alt+Insert , this keyboard shortcut can be used to
generate frequently used code such as constructors, getter, and setter methods, etc.
