常见问题 (FAQ)

Is the keyboard test affected by my keyboard layout or IME?
No. The system uses hardware keycodes. It identifies the physical key pressed regardless of your OS language, layout, or IME (like Unikey).
Why can't I test the 'Fn' or Power button?
Special hardware keys like 'Fn', Power, or screen brightness controls are intercepted by your Operating System or BIOS at a low level. They do not send key events to the web browser.
