About the Arrow Key Test
The Arrow Key Test tests the four arrow keys on their own. Useful when only the direction keys have stopped responding in games or spreadsheets. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Diagnosing arrow keys that stopped working in one application.
- Checking the arrow cluster on a compact keyboard.
Frequently asked questions
My arrows work here but not in Excel. Why?
Almost always Scroll Lock. With it on, the arrow keys scroll the sheet instead of moving the cell cursor. Press Scroll Lock once and try again.
Why does a key light up in the wrong place?
The test reads the physical key position, not the printed letter, so a non-QWERTY layout will light the key that sits in that position on a US keyboard. That is correct behaviour — it means the test works the same on AZERTY, QWERTZ and Dvorak.
Some keys do nothing at all. Is my keyboard broken?
Not necessarily. Browsers keep a few combinations for themselves — F11, F12, Ctrl+W, Ctrl+T, Cmd+Q, Alt+Tab and the Windows key among them — and act on those instead of passing them to the page. Media keys, Fn-layer keys and macro keys usually never reach the browser either.
Is anything I type recorded?
No. The test runs entirely in your browser tab, keeps only which keys were pressed, and forgets even that when you close or reload the page. Nothing is sent to a server.
Do I need an account to use the Arrow Key Test?
There is no cost and no cap. The Arrow Key Test is not a demo of a paid product, so nothing is held back or watermarked.
Does anything I enter leave my computer?
No. The Arrow Key Test runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What problem does the Arrow Key Test solve?
Typical uses: diagnosing arrow keys that stopped working in one application. Checking the arrow cluster on a compact keyboard. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Do I need to install anything to run this test?
No installation, no extension and no driver. The Arrow Key Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
