Frequently asked questions
What is keyboard ghosting?
Ghosting happens when a keyboard cannot register certain combinations of keys pressed together, because of how its matrix is wired. Gaming keyboards with n-key rollover avoid it, and holding several keys here reveals the limit.
Why does a key not light up on the tester?
Press it again firmly and try a few times. If it still stays dark, the switch may be dirty or worn, or the key may be reserved by your system or browser, such as some media keys.
What is the key code used for?
The key code tells you which physical key the browser received. It helps developers write shortcuts, and it helps you confirm that a remapped or foreign-layout key sends the code you expect.
Is Keyboard tester free?
Yes. Keyboard tester on Toolipedia is free to use, with no sign-up and no watermark.
