In the following example, when ALT-L is pressed, the text field gains the focus. 

    // Create text field
    JTextField textfield = new JTextField(25);
    
    // Create label and associate with text field
    JLabel label = new JLabel("Text Label");
    label.setDisplayedMnemonic(KeyEvent.VK_L);
    label.setLabelFor(textfield);
