Rapid Trigger Test

Times one key’s presses and releases while you tap it, so a run with rapid trigger off can be compared with one with it on.

For proof, record run A with rapid trigger off and run B with it on: same key, same finger.

Why a short tap counts only with rapid trigger

The same finger movement through two switches. A fixed-point switch releases only once the key rises back above its reset point; rapid trigger releases the moment the key turns upward, and presses again the moment it turns down.

Linear and tactile mechanical switches reset close to their actuation point, clicky ones about half a millimetre above it. Rapid trigger keyboards usually allow 0.1 mm or less.

What a browser can and cannot see

It receives the moment a key goes down and the moment it comes up, from any keyboard, but not how far the key moved. So no page can read your actuation point or sensitivity. What it can show is the effect: with rapid trigger on, the key releases as soon as your finger turns upward, so it spends less of each tap released and comes back into play sooner.

Rapid trigger

A setting on magnetic (Hall effect) and some optical keyboards: the key releases as soon as it starts moving up and presses again as soon as it moves down, by a set sensitivity such as 0.1 mm, instead of at fixed points in its travel.

Quick answers before you test

Can a website test rapid trigger?

It can test the effect, not the setting. A browser receives each key-down and key-up but not how far the key moved, so the proof is a run with rapid trigger off against one with it on: the release gap shrinks when it works.

What does rapid trigger change?

A normal switch releases only after the key rises back above a fixed reset point. Rapid trigger releases as soon as the key starts moving up, and presses again as soon as it moves down, so short, shallow taps all count.

Will rapid trigger make me tap faster?

Not with full presses: taps per second mostly measures your finger, and most people top out around five to seven a second. It helps with short taps, flutter and stopping a strafe the instant you lift.

Does it work with a mouse?

Yes. Click a mouse button on the pad instead of pressing a key: mice with rapid trigger buttons show the same shorter release gap.

What the result actually measures

The first key pressed while the pad is on screen, or the mouse button clicked on it, is recorded for five seconds: every down and up with the event’s own timestamp, key repeat ignored. From those come the taps per second (first press to last), the median time each press was held, the median and shortest time released between taps, and the share of each tap spent released. A press or gap under 5 ms is flagged as a contact bounce. Runs A and B are compared median for median, and a change in release time counts as clear only when it is larger than the spread of your own taps. The simulator runs a finger stroke through two switch models — a fixed reset point, and rapid trigger with its sensitivity and optional continuous mode — and counts the presses each registers.

Measurement boundary: A browser cannot read key travel, actuation point or sensitivity, and an operating system adds its own event timing; the numbers are always the keyboard and your finger together. Release times also depend on how you tap, so compare A and B with the same key, the same finger and the same style. Some keyboards apply rapid trigger per key or per profile: check that the profile you set is the one in use.

How to interpret the output

Released between taps

How long the key stayed up between presses. Rapid trigger shortens it, because the key re-presses the moment your finger turns downward instead of after it passes the actuation point again.

Held per tap

How long each press lasted. With rapid trigger the key lets go as soon as you lift, so presses usually get shorter too.

Taps per second

Mostly your finger. A change of a tap or two a second between A and B is normal variation unless the release time moves with it.

Troubleshooting unexpected results

A and B look the same

Check that the keyboard software saved the setting to the active profile, that rapid trigger is on for the key you tapped, and that you tapped the same way both times. With full presses the difference is small; short, quick taps show it best.

The test does not start

Scroll until the pad is on screen, click on the page so it has focus, and press a letter or the space bar. Arrow keys, Tab and function keys are left for moving around the page.

Presses under 5 ms appear

A finger cannot press and release that fast; the switch is bouncing. Clean or replace the switch, or check it in the keyboard chatter test.

Frequently asked questions

How do I test rapid trigger?

Run the tap test once with rapid trigger off and once with it on, on the same key. If rapid trigger works, run B leaves the key released for less time between taps than run A.

Is there a rapid trigger test for a mouse?

Yes: click the pad with the mouse button instead of pressing a key. The same press time and release gap are measured.

What is a good rapid trigger sensitivity?

Most players use 0.1 to 0.3 mm. Lower reacts to smaller movements but can trigger from a resting finger; the simulator shows how sensitivity decides which small movements count.

What is continuous rapid trigger?

Normal rapid trigger works only while the key is below its actuation point; above it the key behaves like a fixed switch. Continuous rapid trigger stays active until the key is fully released, so presses start as soon as the key moves down anywhere in its travel.

Is rapid trigger the same as Snap Tap?

No. Rapid trigger is about one key pressing and releasing sooner; Snap Tap decides what happens when two opposite keys are held. The Snap Tap test checks the second.

Can it measure my actuation point?

No page can: the keyboard sends only pressed and released. Set the actuation point in the keyboard’s software and use the simulator to see what it changes.
