Function row and arrow key check
Confirm F-row, arrows, Delete, Home, End, Page Up, and Page Down where your keyboard exposes them to the browser.
Compact keyboard diagnostics
Run a full pass after remapping, firmware changes, keycap swaps, or compact keyboard repair.
Fn and layer test limits
The page can test browser-visible outputs from layers, but it cannot directly inspect firmware-only Fn behavior.
Related 60 percent keyboard tester
Use the 60 percent page if your keyboard has no dedicated function row, arrows, or navigation cluster.
Help
What makes a 75 percent keyboard different?
A 75 percent keyboard usually keeps the function row and arrows in a compact layout without a numpad.
Can this test firmware layers?
It can test the output a layer sends to the browser, but not the firmware layer state itself.
