How to read results
If one key produces extra repeated events at very short intervals compared with your normal tapping rhythm, that key may have chatter. Browser timing is useful for detection, but not a laboratory-grade measurement.
Instructions
- Choose a key you want to test.
- Tap the same physical key repeatedly at a steady pace.
- Watch the event list and the interval values. Unexpected extra repeats can indicate chatter.
Typical chatter signals
- Repeated duplicate keydown events with very short intervals
- Input that appears more times than your actual presses
- Unstable behavior on one specific key while others remain normal
