Mouse Button Test

Inspect primary, secondary, middle, back and forward buttons and wheel directions inside the test area. View held states, counts, coordinates and events. Browser events do not replace hardware diagnostics.

Start a new test, then use this area

Blue: held; green: press observed. The diagram does not simulate mouse buttons.

Negative wheel deltaY is up, positive is down; deltaMode 0/1/2 means pixels/lines/pages. Blur or stopping clears held states; release is a page cleanup record, not actual mouseup. Left/right refer to logical primary/secondary buttons and depend on OS settings. Side-button navigation or gestures may remain browser-controlled. Missing events do not prove hardware failure.

Buttons, coordinates and event records are not uploaded. Stopping retains results; a new test or leaving clears them.

Processed content stays in this page’s memory and cannot be recovered after clearing or closing.

About this tool

Inspect primary, secondary, middle, back and forward buttons and wheel directions inside the test area. View held states, counts, coordinates and events. Browser events do not replace hardware diagnostics. Only preparation/export actions are reported; event details, keys, coordinates and observations are not uploaded.

How to use

  1. Start a new test and use the keyboard or mouse in the test area; KeyCode also provides direct lookup.
  2. Inspect held states, counts and events; focus loss releases displayed states.
  3. Stop and copy/download event JSON; KeyCode lookup also exports JSON/CSV. A new test or leaving clears records.

Frequently asked questions

Does this automatically certify hardware?

No. Keyboard/mouse tools show events received by the browser; OS shortcuts, Fn and browser gestures may be intercepted. Screen inspection is manual. The 10-second preparation limit does not limit your testing session; closing the page ends it.
