Press keys and verify that their key, code, and pressed state reach the browser.

Privacy

Key events received while the page is active are displayed only in browser state; typed content is not stored or sent to a server.

Requirements

OS- or browser-reserved shortcuts and input while the page lacks focus may not be captured. The visual layout does not represent every physical keyboard model.

Common questions

Will every browser or operating-system shortcut appear?: No. Keys or combinations reserved and handled first by the browser or operating system might never reach the page.
Does it identify characters for every physical keyboard layout?: It shows KeyboardEvent key, physical code, repeat state, and modifiers. It does not diagnose the underlying cause of hardware faults.
