Keyboard Test – Check Every Key Online

Chatter Test
This test helps you check whether any keys on your keyboard are registering unintended double presses, also known as chatter.
When you click the “Start Test” button, 20 words will appear. Type each word carefully.
How to Test Your Keyboard
To run a keyboard key test, simply click the test area above once. Then press each key on your keyboard one by one to see which keys are detected. Working keys will be highlighted on the keyboard simulation, while your most recent key presses will appear in the panel.
1. Activate the test area
First, click the keyboard test area. Your browser will then begin detecting keyboard input.
2. Press every key one by one
Test every section of your keyboard, including letters, numbers, Space, Enter, Shift, Ctrl, arrow keys, and the numeric keypad.
3. Identify keys that are not working
Keys that do not respond on the screen may be affected by a hardware fault, dirt, a switch problem, or a software issue.

How to read your keyboard test results
When a key lights up on the on-screen keyboard, its input has reached the browser. Use the checks below for keys that never respond, work intermittently or create more than one input from a single press.
The key lights up
The press is being detected. Try key combinations and hold the key briefly to complete your check.
The key never appears
Retest it in another browser, USB port or computer. If the problem remains, a hardware fault becomes more likely.
One press types twice
This may be keyboard chatter or double typing. Use the Chatter Test above to inspect repeated inputs from the same key.
Note: Fn, Windows, brightness and some media keys may be handled by the operating system before the browser receives them. A missing response for these keys does not automatically mean the keyboard is faulty.
