What it measures
Buttons
Left, right, middle, and extra buttons, caught inside the pad so the browser does not steal the click.
Wheel
Scroll direction and whether notches arrive one at a time or in a smear.
Double-click
The gap between two clicks, so a sticky switch is visible.
Polling
An estimate from pointer events, plus a trail that shows acceleration and jitter.
Questions
Will this change my pointer speed?
No. System sensitivity stays where you set it. The page only draws the movement it receives.
Middle-click opens a tab.
Press inside the test pad. The pad is where the buttons are captured, so the browser chrome does not act on them.
