Universal Media Controller

Description

YouTube-style keyboard shortcuts for any video or audio. You choose which sites to allow — nothing is collected. 🎮 Universal Media Controller adds YouTube-style keyboard shortcuts to HTML5 video and audio on the web — play/pause, seek, speed, volume, mute, fullscreen, Picture-in-Picture, and more. 🌟 Key Features: • Control almost any page media without hunting for player buttons • Familiar shortcuts (K / J / L, arrows, </>, 0–9, M, F, P, +/-) • You choose site access: allow this site, or all sites — nothing broad is forced at install • Remap or disable any shortcut • Optional site profiles (Twitch, Netflix, YouTube) to avoid key clashes • Blacklist domains where you do not want hotkeys • Open source, runs locally, no accounts or analytics 🔐 How site access works: After install, open the extension popup on a video page and choose: • Allow this site — recommended if you only need a few domains • Allow all sites — convenient everywhere (Chrome shows its standard permission prompt when you choose this) ⌨️ Keyboard Shortcuts: • K - Play/Pause • J/L - Skip backward/forward 10s • Left/Right arrows - Skip 5s • </> - Decrease/Increase speed • 0-9 - Jump to percentage • M - Toggle mute • F - Toggle fullscreen • P - Picture-in-Picture mode • +/- - Volume control • [/] - Navigate subtitles 🔒 Privacy & Security: • No data collection • No external tracking • Works offline • Optional site access — you decide what to allow • Open source code 💡 Perfect for: • Online courses and educational videos • Movie and TV show streaming • Podcast and audio content • Language learning with subtitles • Multi-tasking with Picture-in-Picture 🚀 Regular updates and active development! 📝 Note: Some features may not work on websites that use custom video players, DRM, or have strict security policies. If keys clash with a site, disable those shortcuts or enable a site profile in Options. 🔧 Having issues or suggestions?
