🖱️ Mouse Double Click Test (Chatter)
Click the pad and this tool measures the time between your clicks. If a click registers twice within a few milliseconds — a sign of a worn mouse switch (chattering) — it's flagged in red. Adjust the threshold, watch the interval log, and confirm whether your mouse double-clicks on a single press.

FAQ
What is mouse chatter?
Chatter (or double-clicking) is when a worn mouse switch registers one physical press as two clicks, usually appearing as unintended double clicks.
What threshold should I use?
Most intentional double clicks are 120ms or more apart. Unintended chatter is usually under 70ms, so the default 70ms is a good starting point.
Does this work on a laptop trackpad?
Yes, but chatter is a mechanical-switch problem, so it mainly matters for external mice.
