Mouse Test

As soon as you open this page, the mouse picture above follows what you do in real time—you don’t have to click inside the dashed box first. The thumb back/forward buttons are safe to try here: they won’t send the browser backward or forward through history. To test the wheel, move the pointer into the dashed box and scroll. The three lines below say, in plain words, roughly where the pointer is, which buttons are held, and how the wheel last moved.

To test the scroll wheel, move the mouse into the dashed box, then roll the wheel.

What’s held down nowNo buttons detected as pressed right now

How the wheel last movedYou haven’t scrolled inside the dashed box yet. Move the pointer there and roll the wheel to see a reading here.
