Keyboard Tester
Press keys to test real-time detection and physical key mapping. The keyboard view is responsive and fits the available screen width.
Some function keys may still be controlled by your browser or operating system. If you’d like to test F1-F12 keys, hold FN while pressing the function key.

Function key capture is ready. Browser or OS-reserved shortcuts may still override web pages.

Help & Troubleshooting
- Click the page first if keys do not respond.
- Some OS/browser shortcuts are reserved and cannot be captured.
- F1-F12, Esc, and Print Screen are captured where the browser allows it. OS-level actions may still win.
- On many Macs, top-row keys trigger media controls unless “Use F1, F2, etc. as standard function keys” is enabled.
- The Fn key is often handled by macOS at system level and may not be detectable in browsers.
- Mobile devices have limited keyboard testing support.
- Physical legends may differ from the selected layout.
FAQ
Why is a key detected but not highlighted?
The browser event may exist while the selected visual layout does not include that key code. Use the unmapped key note as a clue.
Do held keys spam history?
No. Hold repeats are handled cleanly and without duplicate flooding.
