About this test

This test shows every button event your mouse sends to the browser: left, right, middle, and the back and forward side buttons, plus wheel steps in both directions. It is a quick way to confirm a new mouse works, to spot a button that stopped responding, or to check that remapping software is sending the right buttons.

How to use this test

  1. Move the pointer into the dark test area.
  2. Press each button, including side buttons, and scroll up and down.
  3. Check the counters. A button that never increases is not being detected.

Frequently asked questions

Why don't my side buttons register?

Some drivers remap side buttons to keyboard shortcuts. Reset the mapping in your mouse software so they act as buttons 4 and 5.

Does this test DPI or polling rate?

Use the dedicated Mouse DPI Test and Polling Rate Test for those measurements.
