THE CONTEXT:
This canvas is 1,000,000 pixels tall.
While no website is comically this big, the physics mirror the daily frustration of navigating long content. Whether you are reading a 500-page PDF contract, scrolling back to the beginning of a years-long group chat, or browsing a massive photo library, standard inputs create friction.
WHY STANDARD INPUTS FAIL:
Scrollbars: Mathematically imprecise. Moving the handle by just 1 screen pixel skips over thousands of pixels of content. You cannot land on a specific paragraph.
Scroll Wheels: Physically exhausting. At standard settings (~100px per step), traversing this map requires 10,000 steps. That is roughly 2,000 full finger rotations. This repetitive motion is slow and can aggravate RSI or arthritis.
Touchpads: Ergonomically poor for long distances. You are forced to "clutch"—swipe, lift, reset, swipe—hundreds of times. It causes finger fatigue and makes it difficult to track moving content.
THE MISSING LINK:
Web browsers (Chrome, Edge, Firefox) actually solved this problem years ago with "Middle-Click Scrolling". It is the gold standard for navigation. However, this feature is locked inside the browser. Try middle-clicking in Discord, Spotify, Word, or File Explorer. Nothing happens. You are forced back to the scroll wheel.
THE SOLUTION: WinAutoScroll brings that "browser-exclusive" superpower to the entire operating system. It acts like cruise control for your screen: push the mouse far to cross huge gaps instantly, or pull it close to slow down for reading speed without repetitive physical effort.
CALIBRATION TEST:
Locate the 10 Targets scattered across the map. STOP AND HOLD POSITION on each target for 0.05s to verify your sensitivity settings.
