tmux Ref by Libor Benes (Dr. B)

🏛 About tmux Ref:
tmux's keybindings are easy to forget between sessions, and reaching for man tmux or a browser tab breaks your flow.

tmux Ref surfaces a curated, searchable reference in one sidebar, color-coded and copy-ready, without leaving the page you're on.

📐 Desktop Sidebar Design:
🔎 Live Filter: Type to narrow all 45 commands by keybinding, command text, description, or category.
🗂 Six Categories: Sessions, windows, panes, copy mode, layout, and misc, each with its own header.
📋 Click-to-Copy: Click any row, or focus it with Tab and press Enter or Space, to copy that command to the clipboard.
🎨 Neon Terminal Theme: Commands in green, categories in cyan, on a near-black background for high contrast.

⚙ How It Works — Nothing Sent Anywhere:
• tmux Ref's entire 45-command reference is bundled as static, hand-authored data; nothing is fetched or looked up externally.
• Filtering and rendering happen entirely client-side.
• Every row and label is built with safe, text-only DOM methods — nothing is ever inserted as HTML.
• The only privileged action is writing a copied command to your clipboard when you click it.

📚 Command Coverage:
There's no single canonical list of "the tmux commands that matter." tmux Ref's built-in reference covers 45 of the ones you'll actually use — session, window, and pane management, copy mode, layout cycling, and a handful of miscellaneous commands — grouped into 6 categories you can filter by name.

📊 What You See:
📇 Category Header: Groups commands under sessions, windows, panes, copy mode, layout, or misc.
⌨ Command Row: The keybinding or command, its description, and a copy affordance.
🔎 Empty State: A clear "no matches" message when your filter returns nothing.

🖥 Features:
🎨 Neon Color Coding — Commands in green, categories in cyan, magenta focus states — always readable, always high-contrast.
🔎 Instant Filtering — Narrows the full list as you type, across commands, descriptions, and categories.
📋 One-Click Copy — Copy any command straight to the clipboard from the keyboard or mouse.
🗂 Six Clear Categories — Sessions, windows, panes, copy mode, layout, misc.
🪶 Zero Outbound Network Footprint — The extension itself never contacts any server.

🎯 Perfect for:
• Developers and sysadmins who use tmux daily but don't have every keybinding memorized.
• Anyone new to tmux who wants a browsable reference instead of scrollback of forgotten man output.
• Programmers and instructors demonstrating tmux to others.
• Students learning terminal multiplexing for the first time.

🔒 Security-First Architecture:
✅ No Data Collection — Explicitly declared in manifest.json.
✅ No Telemetry — No analytics, no tracking, no third-party requests.
✅ No eval() or innerHTML — Safe, text-only DOM methods throughout.
✅ No Persistent Storage — No preferences or data are saved; nothing survives beyond the current sidebar session.
✅ No Network Access — No host permissions requested, no network requests made.
✅ Permissions Matched to Function — clipboardWrite only, for the Copy action — nothing more.

⚠ Limitations:
📚 Curated, Not Exhaustive — 45 of the most commonly used commands and keybindings are covered; less common commands and custom bindings aren't included.
🖥 Desktop Only — Firefox sidebars are not available on Android.
⌨ Assumes Default Bindings — Keybindings reflect tmux's default Ctrl+b prefix; they won't match a remapped config.
🧠 Reference Only — Doesn't run tmux, detect a terminal, or read your config; it's a lookup tool, not an integration.
