The left button, measured
The left mouse button does nearly all of your everyday clicking, which makes it the natural place to measure speed. This test counts left clicks for five seconds, starting from your first click inside the box. Right clicks are ignored. When time is up you see your clicks per second, a rating, the total and your best.
Because the left button is the one you use most, it is also the one where small technique changes show up fastest in your scores.
Index or middle finger
Two fingers can sensibly work the left button.
Index finger. The default for most people. It is the most practiced and usually the most independent finger, so it can move quickly while the others stay still. Many people get their best five second score with it.
Middle finger. A few people move the middle finger onto the left button for speed tests. It is longer, which can make a claw shape easier, and some find it holds a pace better over a longer run. It feels strange at first.
Run five tries with each and compare the averages in the Your scores panel. Then choose one. If you switch back and forth, your trend chart stops meaning much.
Resting your finger on the button
Where your finger waits between clicks matters more than people expect. A finger that lifts high above the button has to travel down before every click and back up after it. A finger that stays in light contact with the button only has to press and release.
Try this setup before each run:
- Place the fingertip on the front part of the button, not the middle.
- Let it rest there with almost no pressure.
- Keep the other fingers still and relaxed on the mouse.
- Anchor your wrist so that only the finger moves.
- Make your first click from that resting position.
The fingertip gives you a short, direct press. Pressing near the front of the button also tends to need less force than pressing near the hinge.
Relaxed beats tense
A tight hand feels powerful but slows down within a couple of seconds. Aim for the lightest press that still registers. If your hand starts to ache, stop for the day.
Once your left click is steady, compare it with your other button using the right click CPS test. For two finger styles, see the butterfly click test.
