Reading your results
Try each key, then hold several keys together to see the detected combination. Left and right Shift, Ctrl and Alt are tracked separately.
An unmarked key does not necessarily mean a broken key. Fn, media keys and shortcuts such as Alt + Tab, Command + Q or Ctrl + W may be handled by your operating system or browser. The diagram uses QWERTY; actual characters appear in the history.
Switching tabs or windows pauses the test automatically. Previously detected keys stay marked.
Keys are captured only while you enable testing on this page. Keystrokes are not saved or sent to a server. Stop testing before entering personal information.
