Hi Kalam,
You have to add a KeyListener to your applicacion ( if the keys work all the time ) or to the JTabbedPane ( if the keys only work when the tabbedPane has focus).
Once you do that the component is listening for the KeyEvent ( all keys - including tab fire events )
Here's some (untested) sample code;

JTabbedPane tab = new JTabbedPane();
// now add 5 tab panels
for( int i = 0 ; i < 5 ; i ++ )
    tab.add( new JPanel() );
tab.addKeyListener( new KeyAdapter() {
    public void keyPressed( KeyEvent e ){
    
        if( e.getKeyEvent() == ( KeyEvent.VK_TAB & VK_CONTROL ) )
            // do something.
    
    }
});
