Click, scroll, or double-click to test
Instructions: Move your mouse inside the canvas to track movement. Test left, right, and middle click. Scroll up and down. Double-click to test timing.
How this test works
We listen for pointer, click, and wheel events to show button states, scroll direction, and movement position. Processing stays local to the page.
- • Left, right, and middle clicks light up their indicators while pressed.
- • Scroll events show direction and count so you can confirm wheel behavior.
Troubleshooting
- • Place the mouse on a non-glossy surface so the sensor can track reliably.
- • For wireless devices, replace the battery or charge, then reconnect.
- • Try another USB port or receiver position to avoid dropout.
- • Disable third-party gesture tools temporarily if they intercept buttons or scroll.
- • If movement feels slow, raise pointer speed in your OS instead of maxing DPI first.
Quick steps
- • Move the mouse to see live position updates.
- • Click left, right, and middle; the indicators should light while held.
- • Scroll up and down; the counter should increment in the right direction.
- • Try a drag by holding left click while moving to confirm it stays held.
If clicks don't register
- • Click inside the tester once to ensure the page has focus.
- • Switch to a different surface or mouse pad to improve tracking.
- • Reconnect the mouse or try it on another device to rule out hardware faults.
- • Remove dongle extenders or hubs that may add lag or drop packets.
If scrolling is missing or jittery
- • Turn off smooth-scrolling extensions and test again.
- • Clean the wheel to remove dust that can cause bouncing.
- • On touchpads, use two-finger scroll with a longer stroke so the browser registers the gesture.
- • Toggle natural scroll in OS settings if direction feels reversed.
Windows pointer checks
- • Settings > Bluetooth & devices > Mouse: set primary button and pointer speed.
- • Turn off Enhance pointer precision if you want raw tracking for games.
- • Device Manager: reconnect if the mouse shows an error; update the driver if needed.
macOS pointer checks
- • System Settings > Mouse or Trackpad: set tracking speed and scroll direction.
- • Disable tap-to-click briefly if stray taps trigger clicks during testing.
- • Remove and re-add Bluetooth mice if lag appears after sleep.
Fix double-clicking when single-clicking
- • Lower double-click speed in OS settings and retest.
- • Clean the left switch with compressed air; debris can cause bounce.
- • If double-clicks persist, the switch may be worn; consider replacing the switch or mouse.
If pointer lags or skips
- • Plug the receiver into a front USB port or short extension to avoid interference.
- • Move wireless routers and hubs a few inches away from the receiver.
- • Switch surfaces; glossy or transparent tables can break optical tracking.
- • Charge or replace batteries before testing fine control.
Trackpad and gesture tips
- • Use two-finger scroll for vertical scrolling and check the counter updates.
- • Turn off palm rejection briefly if taps are ignored during testing.
- • On Windows Precision touchpads, open Touchpad settings to adjust sensitivity and tap behavior.
- • On macOS, toggle Tap to click and Secondary click to match what you expect to see here.
Browser quirks
- • Some extensions change scroll direction or speed; disable them while testing.
- • If clicks are blocked, open an incognito window to rule out content blockers.
- • Keep only one test tab open so events do not split focus.
Tune speed and accuracy
- • Start with a medium DPI (800-1200) and adjust pointer speed in the OS for fine control.
- • Use a consistent mouse pad texture to keep tracking predictable.
- • Turn off angle snapping in mouse software if you need precise diagonal moves.
When to use this test
- • Before gaming or productivity sessions to confirm buttons and scroll are reliable.
- • After spills or cable replacements to ensure the mouse still tracks.
- • When diagnosing phantom double-clicks or missed inputs.
- • While setting up a new desk to dial in speed and scroll direction.
Safety and privacy
- • Pointer and click data stay in your browser and clear when you close the tab.
- • Use a private window if you do not want the permission state remembered.
- • No downloads or drivers are needed to run this test.

FAQ
Do you track or store mouse data?
No. Clicks, movement, and scroll events are handled in your browser only and are not uploaded.
How can I spot double-click issues?
Press the left button repeatedly; the log will show if extra clicks appear. That often points to a switch or debounce issue.
Why is the wheel not detected?
Make sure the page has focus and that smooth scrolling or touchpad gestures are enabled. Some high-resolution wheels send small steps; scroll a longer stroke to see it register.
Can I measure DPI here?
This test shows movement visually. For exact DPI, move a set distance on a measured surface and compare cursor travel in your OS pointer settings.
Does this work with trackpads?
Yes. Two-finger scroll and tap-to-click are shown as wheel and click events as long as the browser has focus.
Can I test side buttons?
Yes. Many mice send side buttons as BrowserBack and BrowserForward; press them to see if they register in the log.
