Scroll the wheel — skip forward and back on YouTube
No keyboard shortcuts, no dragging the progress bar. Hover over the YouTube player and scroll your mouse wheel to jump 5 seconds forward or backward — with a clean center OSD showing exactly where you are.
A zero-UI Chrome extension for youtube.com/watch: wheel-based seek, 5-second steps, and a 0.5s fade-out time indicator in the center of the video.
Core features (MVP)
F1 — Wheel seek on the player
Scroll up to move forward, scroll down to move back — 5 seconds per notch, only while the cursor is over the video player.
- YouTube Player API (seekTo) + HTML5 Video API (currentTime) for progress bar sync
- currentTime clamped between 0 and video duration
- e.preventDefault() with passive: false to stop page scroll while seeking
F2 — Center OSD feedback
Each wheel action shows a semi-transparent popup at the center of the screen — e.g. 1:23 / 10:45 — visible for 0.5 seconds then fading out.
Zero-UI design
No popup, no options page. Install from the store and it works immediately in the background on YouTube watch pages.
SPA navigation
- MutationObserver + yt-navigate-finish to re-attach listeners on new videos
- WeakSet prevents duplicate wheel listeners on the same player
Technical stack
- Chrome Extension Manifest V3
- host_permissions for youtube.com
- Chrome i18n: _locales/en, ko, ja (name & description follow browser UI language)
- content/content.js + content/content.css — no backend, no external libraries
MVP scope & roadmap
- In scope: youtube.com/watch playback pages
- Out of scope (MVP): YouTube Shorts (/shorts/) — different DOM, needs separate selectors
- Future: user-configurable seek interval, Shorts support
User flow
Install once — then only the wheel:
- Install from Chrome Web Store — extension starts in the background
- Open any YouTube watch page and start playback
- Hover the player and scroll the wheel up (forward) or down (back)
- Center OSD shows current time / total duration, then fades away
Who it's for
- Anyone who scrubs through YouTube often
- Users who prefer mouse over keyboard shortcuts
- Viewers who want instant, visual feedback while seeking
Privacy
- Runs only on youtube.com — no data sent to developer servers
- Does not read watch history, accounts, or comments
- No analytics or tracking in the MVP
YouTube Wheel Master exists for one job: make seeking feel as natural as scrolling. Install and scroll — that's it.
