Keyboard tests
Use these tests when a key does not respond, responds late or seems to type something else, or when you want to check a new or second-hand keyboard before you rely on it.
Tests in this section
- Keyboard testPress every key and see which ones register, with ANSI, ISO and Mac layouts.
- Ghosting testHold several keys at once and see which combinations your keyboard can report.
- Chatter testFind keys that type twice: each press timed, repeats too fast for a finger flagged.
- Mac keyboard testKeyboard test with Mac key names, for MacBook keyboards and the Magic Keyboard.
Which keyboard test do you need?
Start with the keyboard test: it shows a full keyboard map and lights up each key as you press and release it. In a couple of minutes you know which keys work, which never respond and which do not reach the browser at all.
Layouts differ physically: ANSI keyboards (common in the US) have a wide one-row Enter key, while ISO keyboards (UK and most of Europe) have a tall Enter key and an extra key next to left Shift. The map can show both, plus Mac key names.
Before you blame the keyboard
- Try another USB port, cable or receiver, and charge or replace the batteries of wireless keyboards.
- Check that the operating system's keyboard language matches the printed keys: a wrong language setting moves symbols, not switches.
- Turn off accessibility features such as Filter Keys or Sticky Keys if keys feel delayed or modifiers stay on.
- On laptops, test with an external keyboard too: if it works, the problem is the built-in keyboard, not the software.
