    FAQ

    Keyboard Double Click FAQ

    + What is keyboard chatter?

    Chatter is one press that the keyboard sends as two. It looks like a double letter when you type once.

    + How do I test a key?

    Press the suspect key once, slowly. A second event without a second press is chatter.

    + Which keys fail most?

    Often the ones you hit hardest: spacebar, WASD, and modifiers. Test the key that misbehaves in game.

    + Will this repair the switch?

    No. It only shows the extra event. A new switch or keyboard is the hardware fix.

    + Do I need an account?

    No. The tool runs in your browser. There is no signup, and the result shows on this page.
