How to test a mouse online
Click the zone
Focus the capture panel — right-click and wheel won’t open the page menu.
Press buttons
The mouse diagram lights up; event details appear on the side.
Scroll the wheel
See delta values and total scroll for the session.
Read history
The down/up/click/wheel log helps catch stuck buttons and extra clicks.
Frequently asked questions
Why doesn’t right-click open a menu?
Inside the test zone the page context menu is blocked on purpose — the event is still logged.
What are Back and Forward?
Side mouse buttons (often browser back/forward). Not every mouse has them.
How do I test double-click problems?
Click repeatedly on the test area — the log shows each event with timing, so unintended double-clicks from a worn switch become visible.
What does the scroll test show?
Wheel direction and delta values; jumpy or reversed scrolling usually means a driver setting or a failing encoder.
