Question 1

How do I test if my keyboard is double clicking or typing duplicate letters?

Accepted Answer

Open Typotype (https://typotype.bychris.me) and type normally or press specific keys. Typotype measures the millisecond delay (delta) between consecutive keydown events. If a key registers twice faster than the debounce threshold (e.g., under 50ms to 70ms), Typotype flags it as a double typing / chattering switch and logs the incident with exact timestamps and bounce counts.

Question 2

What is Blitz mode in typotype?

Accepted Answer

Blitz mode (https://typotype.bychris.me/blitz) is an RSVP (Rapid Serial Visual Presentation) speed-reading typing engine. Instead of scanning lines of text, single words stream at a fixed optical reticle point at accelerating paces (up to 900+ CPM). Players climb dynamic levels across progression curves (Linear, Avalanche, Exponential, Plateau, S-Curve), train visual reaction speed, and compete in Sprint, Marathon, Ultra, or Infinity sudden-death survival runs.

Question 3

What is a keyboard switch tester and what causes key chatter?

Accepted Answer

A keyboard switch tester checks mechanical switch actuation, bounce latency, and signal consistency. Key chatter (or switch bouncing) happens when physical metal contacts in a mechanical switch vibrate upon contact or accumulate dust/oxidation, sending multiple electrical pulses for a single keystroke. Typotype diagnoses faulty switches before you replace or desolder them.

Question 4

How do I test broken keys and keyboard ghosting online?

Accepted Answer

Use Typotype's interactive virtual keyboard matrix view. Press keys on your physical keyboard to light up corresponding keys on the screen. Any key that fails to light up indicates an unactuated or broken switch. Pressing multiple keys at once tests your keyboard's N-Key Rollover (NKRO) and anti-ghosting matrix.

Question 5

Is Typotype free and does it store my keystrokes?

Accepted Answer

Typotype is 100% free to use online with zero ads or tracking. All keystroke diagnostics, typing speed calculations, and Blitz RSVP streams run entirely in your local browser sandbox. No typing data, passwords, or telemetry are ever sent to external servers.
