What SOCD is
SOCD (Simultaneous Opposing Cardinal Directions) comes from fight sticks, where left + right had to be resolved. On keyboards it decides what A + D or ← + → means: last input wins, both cancel (neutral), or both stay held (off).
SOCD Behavior Check
Snap Tap / SOCD Test
Find out how your keyboard handles two opposite keys held at once. Follow four short steps and the test reads the key events your browser receives to tell last-input priority (Snap Tap), neutral and off apart.

About the Snap Tap / SOCD Test
• SOCD means Simultaneous Opposing Cardinal Directions: what should happen when left and right (or up and down) are held at the same time.
• With last input priority, the newest key wins. The keyboard sends a release for the first key the moment you press the second, even though your finger is still on it.
• With neutral, holding both cancels out. With SOCD off, a standard keyboard simply reports both keys as held and leaves the decision to the game.
• A browser only sees what the keyboard sends. It cannot tell whether the behavior comes from keyboard firmware or from software running on your computer.
• Several rounds are compared because a slip of the finger can look like a different mode. The result is shown once the rounds agree.
• Some games and competitions restrict these features. Since August 2024, Valve's official Counter-Strike 2 servers may kick players whose movement inputs look automated by SOCD features. Check the rules of the game or event you play.
SOCD, Snap Tap and Rappy Snappy explained
Opposing keys held together are a small detail with a big effect on movement in shooters. Here is what the modes mean and how to change them.
Test with the keyboard you play on, in the same mode or profile you use in games, and close key remapping software unless you want to test it.
Snap Tap, Rappy Snappy and SOCD cleaners
Snap Tap (Razer) and Rappy Snappy (Wooting) are firmware features for last-input priority. SOCD cleaners are programs that do the same in software. In a browser all of them look identical.
How to turn it on or off
Look for Snap Tap, Rappy Snappy, SOCD or last-input priority in your keyboard software or web configurator, often per profile or per key pair. Re-test after changing it, because some settings only apply to selected keys.
Why the switch gap matters
When changing direction, the gap between releasing one key and pressing the other decides how fast you stop. SOCD handling makes it close to 0 ms; without it, the gap depends on your fingers and switch travel.
Rules and fair play
Some titles and tournaments forbid SOCD features; Valve's official CS2 servers have kicked players for automated counter-strafing since August 2024. This page only reports what your keyboard does; follow the rules of each game.
Snap Tap / SOCD Test FAQ
What SOCD modes do, how this test reads them and where they are allowed
What is Snap Tap?
Snap Tap is Razer's name for last-input priority SOCD handling: when you hold A and press D, the keyboard releases A for you so only D is active, and brings A back when you let go of D. Wooting calls a similar feature Rappy Snappy.
How does this test tell the modes apart?
It reads the key events in order. Last-input priority sends an extra release of the first key and re-presses it later; neutral sends the release but never the second key; with SOCD off, both keys are reported as held with no extra events.
Can the test tell hardware Snap Tap from a software SOCD tool?
No. Firmware features and programs such as SOCD cleaners all produce the same key events in the browser. If you want to know which one is active, turn the software off and test again.
Is Snap Tap allowed in games?
It depends on the game and the event. Valve announced in August 2024 that its official Counter-Strike 2 servers may kick players using such inputs, and some tournaments ban them. Other games allow them. Check the current rules before you play.
How do I turn Snap Tap or SOCD on or off?
Use your keyboard's software: for example Snap Tap in Razer Synapse, Rappy Snappy or SOCD settings in Wootility, or the equivalent option in other brands' apps and in web configurators. Then run this test again to confirm the change.
