Button Detection Coverage
What mouse buttons can you test?
This mouse button test focuses on detecting button events inside your browser. You can test the most common mouse buttons and see whether each one registers correctly.
01
Left mouse button
Test whether your primary left click is working properly for normal clicking, selecting, dragging, and daily use.
02
Right mouse button
Check whether your right click is detected without opening the browser context menu inside the test area.
03
Middle mouse button
Press the scroll wheel to test whether your middle click is registering correctly.
04
Side buttons
Test browser-detectable side buttons, usually used for back, forward, gaming shortcuts, or custom mouse actions.
05
Extra button codes
If your mouse has extra buttons and the browser exposes them, the tool can show extra button detection and button code details.
06
Button response score
Get a quick button score based on which main mouse buttons respond during the test.
Quick button testing rule
If a button does not register here, test the same mouse in another browser and another computer. If it still fails, the issue may be related to the mouse hardware, driver, or button mapping software.
How to Test Mouse Buttons
How to use this mouse button test
Use this tool like a focused mouse button diagnostic. Click inside the test area, press each mouse button one by one, and check the live button map, event log, last button pressed, and button response score.
Click inside the button test area
First click inside the testing zone so the browser can focus on the tool and detect your mouse button events.
Press left, right, and middle buttons
Test the main mouse buttons one by one. The live result panel will count each detected left, right, and middle click.
Test side and extra buttons
Press side buttons or extra programmable buttons. If the browser exposes them, the tool will show side or extra button detection.
Watch the visual button map
The mouse map highlights the detected button, so you can quickly confirm whether the correct button is being recognized.
Check the button score and event log
Use the score and event log to find which buttons are working and which button may need deeper troubleshooting.
Button Problem Detection
Common mouse button problems you can check
If your mouse click feels unreliable, this tool helps you check whether the issue is related to a specific button, button mapping, browser detection, or possible hardware failure.
Left click not working
If the left click count does not increase after repeated clicks, the issue may be with the left switch, USB connection, wireless signal, driver, or mouse settings.
Right click not detected
If right click is not detected, test again inside the tool area. If it still fails in other browsers or devices, the right button may need cleaning, repair, or replacement.
Middle click not working
If pressing the scroll wheel does not register as middle click, the wheel button may be blocked, damaged, dirty, or remapped by mouse software.
Side buttons not showing
Side buttons may not appear because some browsers reserve them for back and forward navigation. Try another browser or check your mouse button mapping software.
Troubleshooting rule
If a button fails only in one browser, the issue may be browser-related. If the same button fails in multiple browsers and another computer, the issue is more likely hardware, driver, or button mapping related.
Button Test Result Guide
How to understand your mouse button test result
The button score shows how many important mouse buttons were detected during the test. Focus more on the missing button than the total score, because one faulty button can still make the mouse difficult to use.
85% - 100%
Buttons look responsive
Your main mouse buttons are being detected. If side buttons do not appear, it may be due to browser or operating system behavior.
60% - 84%
Main response detected
Some important buttons are working, but one or more buttons may still be untested or not detected. Test each button again slowly.
0% - 59%
More testing needed
Only a few button events were detected. Click inside the test area first, then test left, right, middle, and side buttons again.
Best result-checking rule
If one button fails here but works in another browser, the issue may be browser-related. If the same button fails everywhere, the issue is more likely related to the mouse hardware, driver, or button mapping.
