The following source creates two internal frames,
each having the same menu -- including a File
menu whose mnemonic is 'f'. Pressing 'Alt-F'
always activates the File menu in the first
JInternalFrame whether it is the active frame
or the other one is. To support mouse-less
operation, 'Alt-F' should activate the File
menu in the JInternalFrame that has the focus.

import com.sun.java.swing.*;

public class Test extends JFrame
{
   public Test()
   {
      super( "Mnem test" );

      setBounds( 0, 0, 500, 500 );

      JDesktopPane desktop = new JDesktopPane();
      getContentPane().add( "Center", desktop );

      JInternalFrame f1 = new JInternalFrame( "Frame 1" );
      JMenuBar mbar1 = new JMenuBar();
      f1.setMenuBar( mbar1 );
      JMenu filemenu1 = new JMenu( "File" );
      filemenu1.setMnemonic( 'f' );
      mbar1.add( filemenu1 );
      JMenuItem item1 = new JMenuItem( "Item" );
      filemenu1.add( item1 );
      f1.setBounds( 0, 0, 250, 500 );
      desktop.add( f1 );

      JInternalFrame f2 = new JInternalFrame( "Frame 2" );
      JMenuBar mbar2 = new JMenuBar();
      f2.setMenuBar( mbar2 );
      JMenu filemenu2 = new JMenu( "File" );
