About Mouse Test
A mouse test checks that every button and the scroll wheel of a mouse are detected. Click, right-click, or scroll inside the test area and the page counts presses of the left, middle, right, and two side buttons, plus wheel steps. It also records the shortest gap between left clicks and counts gaps under 80 milliseconds, which helps reveal a switch that fires twice. Extra buttons handled by vendor software may not be reported.
Also known as: Double Click Test.
Questions about Mouse Test
How do I know if my mouse is double clicking by itself?
Click the left button slowly, one press at a time, twenty or thirty times. If the count of clicks less than 80 ms apart goes up, the mouse sent two signals for one press, which usually points to a worn switch.
Why do my side buttons not register?
Browsers report only the two standard side buttons, back and forward. Buttons that the mouse software maps to macros, DPI changes, or keyboard shortcuts are handled before the browser sees them, so they do not appear here.
