Method

voidsetKeyBinding(String actionKey, int key, int modifiers, AbstractAction action, JComponent component)
set Key Binding 
ActionMap actionMap = component.getActionMap();
InputMap inputMap = component.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
KeyStroke keyStroke = KeyStroke.getKeyStroke(key, modifiers);
inputMap.put(keyStroke, actionKey);
actionMap.put(actionKey, action);
voidsetKeyStroke(JComponent component, KeyStroke keyStroke, Action action)
set Key Stroke 
InputMap inputMap = component.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
if (inputMap != null) {
    ActionMap actionMap = component.getActionMap();
    inputMap.put(keyStroke, KEYID);
    if (actionMap != null) {
        actionMap.put(KEYID, action);
voidsetUpCycle(JComponent comp, int key)
Set the up-cycle key for a particular component As they said in the book (pg 1108), due to a note you have to press the key twice. 
Set upKeys = comp.getFocusTraversalKeys(KeyboardFocusManager.UP_CYCLE_TRAVERSAL_KEYS);
Set newUpKeys = new HashSet(upKeys);
newUpKeys.add(AWTKeyStroke.getAWTKeyStroke(key, 0));
comp.setFocusTraversalKeys(KeyboardFocusManager.UP_CYCLE_TRAVERSAL_KEYS, newUpKeys);
KeyStrokestringToKeyStroke(String s)
string To Key Stroke 
throw new IllegalAccessError("Work in progress");
StringstrokeToPrefs(KeyStroke prefsStroke)
Converts a KeyStroke into a string representation for preference storage. 
if (prefsStroke == null)
    return null;
else
    return String.valueOf(prefsStroke.getModifiers()) + ' ' + String.valueOf(prefsStroke.getKeyCode());
voidsynchronizeKeyboardActions(JComponent sourceComponent, JComponent targetComponent, KeyStroke[] keyStrokes, int condition)
synchronize Keyboard Actions 
for (KeyStroke keyStroke : keyStrokes) {
    ActionListener actionListener = sourceComponent.getActionForKeyStroke(keyStroke);
    if (actionListener != null)
        targetComponent.registerKeyboardAction(actionListener, keyStroke, condition);
voidsynchronizeKeyboardActions(JComponent sourceComponent, JComponent targetComponent, KeyStroke[] keyStrokes, int condition)
Registers all actions registered on the source component and registered them on the target component at the specified condition. 
for (KeyStroke keyStroke : keyStrokes) {
    ActionListener actionListener = sourceComponent.getActionForKeyStroke(keyStroke);
    if (actionListener != null) {
        targetComponent.registerKeyboardAction(actionListener, keyStroke, condition);
voidunregisterKeyBoardAction(JComponent comp, Action action)
unregister Key Board Action 
unregisterKeyBoardAction(comp, action, JComponent.WHEN_IN_FOCUSED_WINDOW);
MwithKeyStroke(M jmi, KeyStroke ks)
with Key Stroke 
jmi.setAccelerator(ks);
return jmi;
