Primary, Secondary and Middle Click
The browser reports button actions as numbers 0, 2 and 1. A left-handed configuration can swap which physical button acts as primary, so labels refer to the action rather than the physical side.
Check your mouse buttons, scroll wheel, side buttons, movement tracking and clicks in real time. A complete browser-based testing desk, built for everyday users and gaming setups.
Use your physical mouse inside the test surfaces. Button zones light up when the browser receives input.
Primary and secondary describe browser button actions, which may be swapped by left-handed mouse settings. Side-button events and middle-click actions may be intercepted by the browser or operating system. Test only on the dedicated surfaces so normal navigation elsewhere on this page is unaffected.
Trace mouse movement, inspect cursor positions and check whether movement events arrive smoothly.
Run a timed primary-button clicking challenge without mixing it with other mouse tests.
This test measures clicks registered by the browser; it is not a measurement of switch latency.
Review registered button presses, releases, wheel direction, timing and input source in one log.

A complete mouse button check should cover the primary and secondary buttons, clicking the scroll wheel, and any back/forward side buttons supported by your mouse.
Not every mouse includes side buttons. Browser or operating-system shortcuts can also prevent some button events from reaching a webpage.
Place your first image URL in the data-image-url attribute.
Move your cursor slowly and quickly across the tracker, then draw a circle or zigzag. Use the trail to notice unexpected jumps or interruptions.
Pointer trails can be influenced by browser event scheduling, OS acceleration, touchpads and display settings. They are not a laboratory measurement of optical sensor accuracy.
Place your second image URL in the data-image-url attribute.
Use the different checks together rather than treating a single missed event as a confirmed hardware failure.
The browser reports button actions as numbers 0, 2 and 1. A left-handed configuration can swap which physical button acts as primary, so labels refer to the action rather than the physical side.
Some mice send browser-back and browser-forward actions. The tester attempts to catch them in its test area, but browsers, extensions or driver mappings can intercept these events.
Wheel events describe an attempted scroll and its delta values. They can originate from physical wheels and trackpads, and delta values may represent pixels, lines or pages rather than mechanical wheel steps.
Two quick presses can be intentional. The tester separately shows browser-recognized double clicks and unusually short same-button intervals. Only repeated, controlled checks can support diagnosing switch issues.
The live tracker draws browser pointer coordinates, distance in CSS pixels and approximate movement speed. Drag gestures count when the primary button remains down through a meaningful movement before release.
A normal webpage cannot directly read a mouse's configured DPI or USB polling rate. Browser mousemove event frequency is displayed as an observed event rate, not an official 125/500/1000/8000 Hz hardware result.
Try these steps before assuming the mouse needs replacing.
Click inside the testing surface, try another browser, then test in another application. Side buttons may be remapped or reserved by the OS.
Check the mouse or operating-system scrolling direction settings. Wheel sign shows event direction, which is not always identical to content scroll direction.
Try deliberate slow presses and look for repeatable short intervals. Check software button mappings and test another machine before blaming a physical switch.
Clean the optical sensor area, use a suitable mouse surface, check wireless battery or interference and close resource-heavy browser tabs.
Open the Live Mouse Diagram and press your physical mouse buttons inside it. The affected parts of the mouse diagram light up and each button counter increases when the browser receives a press.
Yes, where the browser sends those events to the page. The browser identifies primary, middle, secondary, back and forward as button values 0 to 4. Mouse-specific driver mappings can change their behavior.
The layout adapts to small screens. Touching the testing area is treated as a touch preview, not proof of a hardware mouse button. Connect a physical mouse to test its buttons where supported by the mobile browser and operating system.
The tool reports successive same-button click intervals and highlights unusually rapid presses using an adjustable threshold. It cannot distinguish intentional fast clicks from hardware switch chatter with certainty.
Yes. Scroll over the dedicated wheel pad. The test reports vertical and horizontal wheel events if your browser exposes them. Trackpads can create the same events.
No. It reports the rate at which mouse movement events arrive at the webpage. Browsers may combine, throttle or schedule these events, so the result is not a trustworthy measurement of the mouse's hardware polling rate.
Browsers do not provide direct access to DPI, hardware click latency or sensor firmware settings through normal mouse events. The cursor-tracking statistics are based on displayed CSS pixel coordinates and browser event timing.
Some browsers immediately use side-button inputs for navigation, or drivers remap them into other shortcuts. Try the dedicated dark testing surface and compare results in another browser or the mouse's configuration software.
Yes. This widget runs locally without requiring an account and does not itself send mouse events to a server. Site hosting and any other installed analytics scripts have their own policies.
