- Worth noticing
- The keyboard test checks how many keys register at once; the page notes that keys such as Fn never reach a web page.
Field notes
The tests use events already exposed to the browser, and the page cautions that operating-system and browser limits affect what can be detected: Fn is one example of a key that does not reach a web page. Display checks draw full-screen colors, gradients, and pixel patterns, while controller tests are described as working on phones when a controller is paired over Bluetooth.
