With all Swing components, when you want to bind a keystroke to an action,
it is better to use the Swing key binding facility rather than using a
KeyListener.

With the key binding facility, you define Actions that can be performed
and then you bind keystokes to those actions.  This makes things more
flexible, since the bindings can be easily changed without messing with
the actions.  And in this case, the action you need is already defined, so
you just need to bind the keystroke.

   InputMap inputMap = textPane.getInputMap( JComponent.WHEN_FOCUSED );
   inputMap.put(
      KeyStroke.getKeyStroke( KeyEvent.VK_C, InputEvent.CTRL_MASK ),
      "caret-end" );

You could get the required actions from the JTextArea's ActionMap and use
them to create the toolbar buttons.  For example:

   ActionMap map = textPane.getActionMap();
   toolBar.add( map.get( "copy-to-clipboard" ) );
   toolBar.add( map.get( "paste-from-clipboard" ) );
