  1. Press any key to begin. Each key turns green once it works.

Some keys never reach the browser, such as Fn, and some are taken by the system (Win, Print Screen). "Most at once" shows how many keys the keyboard can register together: basic keyboards often stop at 3 or 6. To leave the test using only the keyboard, press Esc three times in a row.
