pressing ctrl-shift right arrow selects the next word in
a JTextField. it doesn't, however, select the rightmost
word in the field.

the following code creates a JTextField. clicking in the word
'one' & then pressing ctrl-shift rightarrow repeatedly selects
the words 'one' 'two' 'three' & 'four' but never 'five'

import javax.swing.*;
import java.awt.event.*;

public class test{

public static void main(String args[]){
JFrame frame = new JFrame();
JTextField text = new JTextField(40);
text.setText("one two three four five");
frame.getContentPane().add(text);
frame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}});
frame.pack();
frame.setVisible(true);
}
}

the same holds for ctrl rightarrow (no shift) which moves the
cursor one word to the right but won't work for the rightmost
word.
