Highlight Extension Chrome

Highlight Extension — Studio Presentation Zoom, Laser Pointer, Keystroke HUD & Web Marker The ultimate presentation, tutorial recording, and visual guidance toolkit for Chrome. Turn any webpage into an interactive presentation stage. Inspired by high-end video recording tools like FocuSee and Screen Studio, Highlight Extension gives you cinematic auto-zooms, real-time laser pointers, live keypress visualizers, resizable spotlights, and news-style highlighters — all live inside your browser without needing post-production video editing. Whether you are teaching, hosting client demos on Google Meet or Zoom, recording YouTube tutorials, or conducting code reviews, Highlight Extension guides your audience's eyes exactly where they need to be. WHAT IS HIGHLIGHT EXTENSION? Highlight Extension is a professional Chrome extension engineered for educators, content creators, product managers, developers, and presenters. It elevates standard browser interaction with studio-grade visual effects: automatically zoom into elements or typing boxes, trail your cursor with a neon laser, showcase your keyboard hotkeys live, isolate UI sections with a spotlight, and permanently annotate text and web layouts. CORE PRESENTATION & RECORDING FEATURES 1. FocuSee-Style Dynamic Auto-Zoom (Alt + Z) - Cinematic Studio Deceleration: Zooms into elements using a silky-smooth camera deceleration curve, completely eliminating jitter, drift, or vertical wobble. - Multiple Smart Trigger Modes: * Hover-to-Zoom (with Circular Progress Ring): Hover cursor over any element for a configurable delay (0.4s – 2.5s) to watch an animated SVG ring fill up and zoom in. * Alt + Hover (Instant): Hold Alt and hover for instantaneous focal zooms. * Click-to-Zoom: Zooms immediately upon clicking an element. * Typing & Input Focus: Automatically and smoothly zooms into search bars, input fields, and textareas when placing your cursor to type. - Edge-Aware Screen Clamping: Left-side menus (like ChatGPT, documentation trees, navigation sidebars) and right-side panels are automatically compensated so text and icons never get cut off or disappear outside the screen boundary. - Soft Perimeter Vignette: Inset cinematic perimeter shadow that gently darkens the outer screen, keeping full focus on the active content. - Auto-Exit Timer & Quick Exits: Automatically and smoothly glides back to normal view after 2.5s (customizable from 1.5s to 5.0s), or exit instantly with a scroll down or double-click. 2. Presentation Laser Pointer & Particle Trails (Alt + L) - Project a glowing neon red laser dot with dynamic trailing particles that follows your cursor in real time. - Makes cursor tracking effortless on large 4K monitors, projectors, and compressed screen recordings. 3. Live Keystroke HUD Visualizer - Displays real-time floating keypress badges at the bottom of the screen. - Perfectly visualizes keyboard combinations (such as Ctrl + C, Cmd + V, Alt + Tab, Shift + Enter) so viewers can follow every shortcut you use. 4. Interactive Spotlight with Dynamic Wheel Resize (Alt + S) - Darkens and blurs the entire webpage while casting a crisp spotlight beam around your mouse pointer. - Dynamic Wheel Scaling: While spotlight is active, hold Ctrl or Alt and roll your mouse wheel to dynamically shrink or expand the spotlight radius from 60px to 300px. 5. Live Canvas Annotations & Directional Arrows (Alt + D) - Freehand Draw Mode: Draw circles, notes, and underlines directly over live web apps. - Directional Arrow Tool: Snap clean callout arrows from point A to point B to direct viewer attention. - Retina High-DPI Canvas: Crisp, anti-aliased rendering on Mac Retina and 4K displays with a 1-click canvas clear button. 6. Tactile Click Audio Feedback & Ripple Waves - Synthesized Click Pop SFX: Built with Web Audio API for zero-latency auditory click feedback (no external audio files needed). - Click Ripple Waves: Smooth animated ripple rings that burst on click, with custom hex color customization. 7. Draggable In-Page Floating Toolbar - A translucent floating dock that sits discreetly on the page. - Features a grab handle so you can drag and reposition the toolbar anywhere on your screen. - Offers 1-click toggles for Auto-Zoom, Laser, Spotlight, Draw, Arrow, and Clear. CLASSIC HIGHLIGHTING & MARKER TOOLS 8. Permanent News-Style Text Highlighter - Select and highlight any text on the web just like a real marker pen. - Choose from 6 distinct styles: Solid, Marker, Glow, Underline, Contrast, and Brush. - Highlights stay intact as you scroll, with one-click individual or global removal. 9.
