Here's the simplest example I could think of.  Tell me if it works like 
what you want.



package quicktest;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JTextArea;
import javax.swing.KeyStroke;
import javax.swing.SwingUtilities;

/**

public class Accelerator {

    public static void main(String[] args) {
       SwingUtilities.invokeLater(new Runnable() {
          public void run() {
             JFrame frame = new JFrame();

             JTextArea ta = new JTextArea();
             frame.add(ta);

             JMenuBar mbar = new JMenuBar();
             JMenu file = new JMenu("File");
             mbar.add(file);
             JMenuItem blarg = new JMenuItem("blarg");
             blarg.setAccelerator(KeyStroke.getKeyStroke(
                     KeyEvent.VK_1, ActionEvent.ALT_MASK));
             blarg.addActionListener( new Blarg( ta ) );
             file.add(blarg);
             frame.setJMenuBar(mbar);

             frame.pack();
             frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
             frame.setSize( 400, 400 );
             frame.setLocationRelativeTo(null);
             frame.setVisible(true);
          }
       });
    }

    private static class Blarg implements ActionListener {

       private final JTextArea ta;
       public Blarg(JTextArea ta) {
          this.ta = ta;
       }

       @Override
       public void actionPerformed(ActionEvent e) {
          ta.append( " blarg" );
       }
    }
}
