Frequently Asked Questions
What does Mouse Test (Buttons & Scroll) check?
Left, middle, and right buttons, live pointer coordinates, and scroll-wheel deltaY on a local pad. Everything stays in the tab.
Do I need to allow camera or microphone access?
No. This tool uses pointer events only - no getUserMedia and no permission prompt for camera or mic.
Is my mouse movement uploaded?
No. Counters and coordinates stay in the page session. Reset clears them; closing the tab drops them.
Why does right-click not open the browser menu on the pad?
While listening, the pad suppresses the context menu so the right-button event can be shown in the readout instead.
