Frequently Asked Questions
Why doesn't a key show up when I press it?
The key may be physically damaged or the connection is broken. Some special keys (like Fn on laptops) are handled by hardware and never send a keycode to the browser.
How do I test for ghost keys?
Hold down multiple keys simultaneously. If a key registers without you pressing it, that is a ghost key — a limitation of the keyboard's hardware matrix. Higher quality keyboards (with N-Key Rollover) prevent this.
