Hi,
I have read through the information that you provided and tried to integrate it into my coding, but I'm really not so clear about that and i don't know how to apply into my coding correctly......can anyone help me? Thanks.
I'm creating an application using the J2SE v 1.4.2_10 SDK with NetBeans 4.1 Bundle. By the way, below is a simple testing program that including component jLabel1, jButton1 and jButton2. Both of the button are hold an event each. I would like to create a hotkey for each button, "F1" key for jButtton1, "F2" key for jButton2. If I click on the "F1" key, the jLabel1 will displays the character "ABC", if I click on the "F2" key, the jLabel1 will display the character "123". Can anyone provide the code to me? Thanks.
* test.java
public class test extends javax.swing.JFrame {
    /** Creates new form test */
    public test() {
        initComponents();
