Middle Button Test FAQ
What is a middle mouse button test?
A middle button test verifies that your scroll wheel click registers correctly without missed inputs.
How do I test middle click?
Press the scroll wheel (middle click) and confirm each press appears in the event log.
How do I test if the middle mouse button works?
Press down on the scroll wheel over the test area above — a working middle button registers a distinct middle-click, separate from scrolling. If clicking the wheel scrolls but never clicks, or nothing happens at all, the middle switch may be worn or the click may be remapped in your mouse software. Try it on a link too: a working middle click opens the link in a new browser tab.
