I've always thought that it is better to use solutions that use a higher level of abstraction compared to solutions that use a lower level. If so, then using key Binding may be a better solution. If this is wrong, please let me know. You can learn about key Bindings here:
http://java.sun.com/docs/books/tutorial/uiswing/misc/keybinding.html
One statement in this tutorial compares key bindings to keylisteners:
An alternative to key bindings is using key listeners. Key listeners have their place as a
low-level interface to keyboard input, but for responding to individual keys key bindings are more
appropriate and tend to result in more easily maintained code. Key listeners are also difficult if
the key binding is to be active when the component doesn't have focus. Some of the advantages
of key bindings are they're somewhat self documenting, take the containment hierarchy into
account, encourage reusable chunks of code (Action objects), and allow actions to be easily
removed, customized, or shared. Also, they make it easy to change the key to which an action
is bound. Another advantage of Actions is that they have an enabled state which provides an
easy way to disable the action without having to track which component it is attached to.
In the future Swing related question should be posted in the Swing forum.
