Re: Am I using the InputMap and the ActionMap correctly?

You should initialize the keybindings in the constructor and not in 
componentActivated().

The short advice:
If you call setAction/InputMap methods, you loose all installed keybindings.
Instead you should call getAction/InputMap on the component that should 
react to the actions and add your keybindings.
These maps are organized hierarchically, so if a component does not have 
a binding for a key/action, it looks in its parent's maps.

For more information see: 
https://docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html

If your bindings still won't work inside a NetBeans Platform 
Application, you should try Benno's tip.
Just supply a new ExplorerManager. (Not sure, if you need to set 
selection and root context to Node.EMPTY)

Johannes
