- The Windows layout lists 91 testable positions; clicked keys are recorded separately from keys received from the keyboard.
Field notes
The page explains that the tester reads physical key positions rather than the characters produced, so it is intended to work across input languages without changing system layout. It offers full-size Windows ANSI and Apple Magic Keyboard layouts, and notes that keys such as Fn may not send signals to a web page. The guide says clicking a key marks it separately from a received hardware signal.
