Complete a test to create a duration-specific result history.
The Manual Spacebar Test counts accepted Space key presses while the ending is controlled by an unlimited Stop action or a custom duration.
The first accepted press starts the timer and counts. Holding the key does not create accepted repeated presses because browser auto-repeat is ignored.
Unlimited mode uses the time between the first press and Stop. A custom-duration mode uses the entered number of seconds.
Compare attempts only when the duration, stopping rule, and keyboard setup match. The recent-results panel shows elapsed time with every stored attempt.
The tool reports accepted presses, elapsed time, and average presses per second. It does not calculate endurance, consistency, reaction time, or keyboard condition.
