Mouse Test
Test every button on your mouse: left, right, middle, scroll wheel, and side buttons. Press buttons inside the test area to verify they register correctly.
How to use this test
- Move your mouse into the dark test area above.
- Click each button: left, right, and middle (press the scroll wheel).
- Scroll the wheel up and down to verify scroll events register.
- Press your side buttons (back and forward) if your mouse has them.
- Double-click anywhere in the test area to verify double-click detection.
- Each button turns green when pressed. A faded green means it was tested successfully.
Testing guide
How to test your mouse buttons and scroll wheel
A mouse button test checks whether every input on your mouse registers correctly in the browser: left, right, middle, scroll up, scroll down, and side buttons. It is the quickest way to confirm a new or suspect mouse is working before blaming software.
Best for
- Checking whether a new or replacement mouse registers every button and scroll direction.
- Diagnosing a button that feels like it clicks but does not always register in games or apps.
- Verifying that side buttons and middle click work after changing drivers or switching operating systems.
How to run the test
- 1Move the cursor into the dark test area so all events are captured.
- 2Click the left, right, and middle buttons one at a time and confirm each lights up green.
- 3Scroll up and down to check that wheel events register in both directions.
- 4Press the side buttons if your mouse has them; these are the back and forward buttons.
How to read the result
A button that lights up on every press is working correctly at the browser level.
A button that sometimes fails to register may have a worn switch, a debounce issue, or a driver problem.
Side buttons that do not register at all are often remapped by mouse software to keyboard shortcuts instead of sending mouse button events.

Frequently asked questions
How do I test if my mouse buttons work?
Open this mouse test, move the cursor into the test area, and click each button. Left, right, middle, scroll up, scroll down, and side buttons each light up green when they register. If a button does not respond, it may be faulty, remapped, or blocked by software.
Why does my middle mouse button not register?
Some mice have a stiff middle click that requires pressing the scroll wheel straight down. If it still does not register, the switch under the wheel may be worn, or your mouse driver may have remapped middle click to another function.
Can this test detect double-click problems?
Yes. The test tracks double-click events separately. If your mouse double-clicks when you only click once, you will see the double-click indicator light up on a single press. That usually means the switch is worn and bouncing.
Why do my side buttons not show up in the test?
Mouse software such as Logitech G Hub, Razer Synapse, or SteelSeries GG often remaps side buttons to keyboard shortcuts or application commands instead of sending browser-detectable mouse button events. Check your mouse software settings and try setting them to default or generic back and forward.
Does this test work with any mouse?
It works with any mouse that sends standard mouse button events to the browser. Wired, wireless, Bluetooth, and USB receiver mice all work. Some gaming mice with heavily customized firmware may send non-standard events that the browser cannot detect for certain buttons.
What causes a mouse button to stop working?
The most common cause is switch wear. Mechanical mouse switches are rated for a finite number of clicks, typically 10 to 80 million depending on the switch type. Debris under the button, a damaged cable, low battery on wireless mice, or a driver conflict can also cause failures.
