- People troubleshooting mouse input in a browser
- Worth noticing
- It says a zero side-button count does not diagnose the mouse; browser mappings and navigation can prevent the event from appearing.
Field notes
The basic result counts five browser-observed signals: pointer movement, main and secondary presses, and vertical wheel events in both directions. Side buttons, hold-and-drag, and double-click are optional checks; the page distinguishes an untouched control from one tried without a signal and notes that browser events are not sensor measurements. Users can save a round, compare rounds, copy a summary, or download a .txt record.
