- Move your pointer into the test area.
- Try left, middle and right clicks, double-clicking and scrolling.
- Read the event counters or reset them.
Before you start
Counts reflect browser events. Double-click recognition follows your device settings; this tool does not diagnose a faulty switch.
Common questions
Can this tell me whether my mouse has a faulty switch?
It shows the events your browser receives. Accidental repeated clicks may be visible, but this is not a definitive hardware test. Double-click recognition also depends on your device settings.
Do scroll counts represent wheel notches?
No. The counters show browser wheel events, which vary with your mouse, trackpad, browser and scrolling settings. Touchscreen taps are not counted as mouse-button tests.
