Introduction to the Keyboard Testing Tool:

1. This tool allows you to check whether the keys on your keyboard are functional or malfunctioning. The testing process is very simple and can be used even by novice users.

2. Instructions: Simply press the key you want to test on your keyboard, and the corresponding key on the tool’s keyboard will change color and emit a keystroke sound.

3. This tool offers two keyboard layout modes: "Windows" and "Mac." Please select the mode that matches your keyboard before use.

4. When you press the corresponding key on your keyboard, the key code will be displayed in real-time in the area above the arrow keys on the tool’s keyboard.

5. For more information on "key codes," please refer to the key code reference table.
