Don't understand the question.

"shift+enter+crtl"

Why make it so complicated?

Complicated key combination aside, what have you tried?
JTextArea text = new JTextArea();
text.addKeyListener(myKeyListener);
Have you even tried to do anything?

"shift+enter+ctrl" means that when all of the three keys are pressed at the same time.
i try it this way but it does't do what i want:

 
 public void keyPressed(KeyEvent e){
                  if(e.getKeyCode()==KeyEvent.VK_SHIFT)
                    if(e.getKeyCode()==KeyEvent.VK_ENTER)
                     send.doClick();  // send is a button
   }

   }

Try

if(e.getKeyCode()==KeyEvent.VK_SHIFT + KeyEvent.VK_ENTER) {...}

I am sorry I still don't see why you want the three key combo.
Without testing you may want to setup three booleans

 
boolean altDown, shitDown, ctrlDown
 

And check the keyCode in keyPressed and then check the three booleans to do the trick.

HTH.

Thanks ,i got it like this.

 
    
 public void keyPressed(KeyEvent e) {
 
 if(e.getKeyCode()==KeyEvent.VK_SHIFT){
       shiftDown=true;
 }
 if(e.getKeyCode()==KeyEvent.VK_ENTER){
        enterDown=true;
 }
  
  if(shiftDown&&enterDown){
     send.doClick();
  }
 }
 public void keyReleased(KeyEvent e) {
     if(e.getKeyCode()==KeyEvent.VK_SHIFT){
       shiftDown=false;
 }
 if(e.getKeyCode()==KeyEvent.VK_ENTER){
        enterDown=false;
 }
 
 }
