Show your hands honor for the strange power they bring you

- Fingers operate with overlapping motions and motor memory, allowing typing speeds that exceed theoretical limits.
- Early computing introduced delays through remote echo, later solved by local echo and buffering to match finger speed.
- Modern interfaces must separate front-end and back-end processing to avoid UI blocking and maintain responsiveness.
- Loading states should prioritize perceived speed, often using optimistic updates and deliberate delays to enhance fluidity.
- Shift and Caps Lock evolved from mechanical toggles to spring-loaded modes, improving typing efficiency through combined gestures.
- Motor memory enables unconscious actions like passwords and shortcuts, requiring interfaces to respect consistency and provide feedback.
- Design details like dead zones, modifier keys before/after drags, and undo shortcuts support fast, error-tolerant interactions.
- iOS scrolling and trackpad gestures exemplify seamless, high-speed finger interactions through momentum and rubber band physics.
- Interfaces should allow overlapping actions, such as dragging while panning or using keyboard and mouse simultaneously, to enable mastery.
- Respecting finger capabilities means prioritizing prompt feedback, avoiding distractions, and maintaining continuous keyboard focus.
