AutoScroll

AutoScroll is a lightweight browser extension that lets you scroll any webpage hands-free with smooth, continuous auto-scrolling. No more repetitive mouse wheel spinning or awkward touchpad gestures — just tap a shortcut and let the page scroll for you.
Features:
- One-key toggle — start and stop scrolling with a customizable keyboard shortcut (default: Ctrl+Space)
- Intuitive speed control — use (customizable) Arrow Up/Down to adjust speed on the fly, or hold the middle mouse button and scroll the wheel
- Stepless speed adjustment — from 0.1 px/frame for slow reading to 20 px/frame for fast skimming
- Bidirectional scrolling — scroll down or up, toggle direction
- Optional HUD overlay — a subtle on-screen indicator showing current speed, direction, and scroll state
- Fully customizable — change keyboard shortcuts, default speed, default direction, and HUD visibility from the popup panel
- Bilingual UI — popup supports English and Chinese (中文), auto-detected from your browser language
- Zero data collection — all processing happens locally in your browser; nothing is ever sent anywhere
