Does your scroll wheel skip?

Scroll your mouse wheel over the test in your browser: steps up and down are counted, with whether it reports lines or pixels, so skips and jumps show.

A mouse test with its five buttons, two ticked as working, and a controller test with both sticks drawn as circles, one dot resting just off centre

A wheel that scrolls the wrong way now and then is a common fault. Count its steps to find out.

Scroll one way, slowly.

Scroll down over the box, slowly. Only the down count should rise. If the up count rises too, the wheel's sensor is sending steps the wrong way.

Lines or pixels.

Notched wheels usually report lines; smooth and free-spinning wheels and touchpads report pixels. Both are normal; the test says which yours sends.

The rest of the mouse.

Test every button, the side ones too, and whether a click comes twice.
