Use this online test to check the keys on a computer or laptop keyboard. A working key lights up on the screen when pressed and remains marked after it is released.
The “Retro” group offers on-screen layouts for Amiga 1200, ATARI 800XL, Commodore 64, IBM Model F XT, Vector-06 °C, and ZX Spectrum 48K. Choose a model and press its keys to see which ones your browser recognizes.
The layout is a visual guide; this test does not emulate the original computer. Some special keys have no equivalent on modern keyboards or may be intercepted by the system.
Try pressing it again, switch the keyboard layout in the test, and repeat the check in another browser or on another device. This helps distinguish a keyboard fault from an operating-system setting or browser limitation.
The browser may not detect Fn, Touch ID, some media keys, or system keyboard shortcuts. On some laptops, the F1–F12 keys must be pressed together with Fn.
