e1005. Listing the Key Bindings in a JTextComponent Keymap

A text component has an additional list of key bindings that is searched after its inputmaps. This additional list is called a keymap. The inputmap mechanism is newer but keymaps were left in place for backwards compatibility.

    JTextArea component = new JTextArea();
    Keymap map = component.getKeymap();
    
    while (map != null) {
        KeyStroke[] keys = map.getBoundKeyStrokes();
    
        for (int i=0; i<keys.length; i++) {
            // This method is defined in e859 Converting a KeyStroke to a String
            String keystrokeStr =  keyStroke2String(keys[i]);
            // Get the action name bound to this keystroke
            Action action = (Action)map.getAction(keys[i]);
        }
    
        // The default action is invoked if a character is typed
        // and no key binding exists in the component's InputMap or Keymap.
        Action defAction = map.getDefaultAction();
    
        // Process all parent keymaps as well
        map = map.getResolveParent();
    }
