How keyboards handle A and D held together
5 waysHandlingReported (A first, then D)In a game
Both heldNo handlingLeft to the game. In CS2 the character stands still
Last input winsSnap Tap, Snappy TappyD takes over at once, even with A still down. Most go back to A when D is released
First input winsRareA stays. D counts only after A is released
NeutralBoth cancelThe two keys cancel out and the character stops
One key always winsAbsolute A / DThe same key wins in either order. Only testing both orders shows this
In each chart you hold A, add D, then release D. A raised line means down. SOCD is opposite directions held at once.
Counter-strafing and Snap Tap
Technique / featureIn CS and Valorant, shots fired on the move spread, so players tap the opposite key to stop. That is counter-strafing. Going from A to D, both keys are down for a moment. A keyboard with no handling reports both and they cancel. With Snap Tap on, A releases the moment D goes down.
Counter-strafing is a techniqueTap the opposite key to stop. Any keyboard can do it
Snap Tap is a keyboard featureSpec sheets may say SOCD or last input priority
Not allowed on CS2 official serversValve said in August 2024 that detected players are kicked
Why a browser cannot test rapid trigger
RTA standard switch actuates and resets at fixed depths. Hall effect (magnetic) switches with rapid trigger track the key's height, so they reset as soon as you start to lift and actuate again as soon as you press.
The keyboard sends only key-down and key-up events, so no web test can measure the actuation point or rapid trigger sensitivity. What you can feel is a faster reset between A and D. Set both in the keyboard's own software.
Frequently asked questions
10 questionsWhat is Snap Tap?
A kind of SOCD handlingSnap Tap is a Razer feature. With A and D held, only the last key pressed counts. Wooting calls it Snappy Tappy, and spec sheets may say SOCD.
Is counter-strafing the same as Snap Tap?
NoCounter-strafing is a technique: you tap the opposite key to stop the character. Snap Tap is a keyboard feature that releases the earlier key for you.
How does this WASD test tell the modes apart?
From what the keyboard reportsHold A, add D and see which key stays. Testing both orders tells "Last input wins" from one key that always wins.
Why keep the keys held?
Early release looks like Snap TapOn a keyboard with no handling, releasing A early leaves only D, which looks like Snap Tap.
What does "Both held" mean?
No handlingThe keyboard reports both keys and the game decides. In CS2 the character stands still.
What does "Resume" mean in the results?
A counts again after DHold A, tap D, then release D. On most keyboards with last input wins, A counts again (step 3). On others, press A again.
Is this a magnetic keyboard test for rapid trigger?
Not for travelOn magnetic (Hall effect) keyboards such as Wooting, SteelSeries Apex Pro or Aula HE, rapid trigger works inside the keyboard, so a web page cannot measure key travel. It can still test Snap Tap.
Can I use Snap Tap in CS2?
Not on official serversIn August 2024, Valve said players caught using Razer Snap Tap or similar input automation on official servers are kicked from the match. Other games and platforms set their own rules.
Do W and S need testing too?
It depends on the keyboardMost keyboards apply this to A and D, and some also to W and S. Switch to W / S and test again. This WASD tester shows what the keyboard reports.
Are my key presses uploaded?
