01 / Instructions
How to use this test
Set a review threshold. Tap one key at a steady, slow pace. Compare the press count with your intentional taps.
02 / Next step
Understand your result
A rapid pair is a clue to review, not a diagnosis. Test a different port or keyboard before attributing it to switch chatter.
03 / Testing methodology
What this test cannot tell you
Fast intentional typing, accessibility software and firmware can produce similar events. Timing is measured by the browser.
