Copy Highlighter

Copy Highlighter highlights text when you copy it in Obsidian, giving a clear visual confirmation that the copy action worked.

Features

• Highlights copied editor text immediately when you press Ctrl+C or Cmd+C.
• Keeps the highlight visible while the copy shortcut is held.
• Supports copied text in reading view and other rendered Obsidian content.
• Includes settings for color, opacity, corner radius, rendered-text highlighting, and fallback timing.
• Works without external services, network requests, telemetry, or file-system access.

Usage

Select text in Obsidian and copy it. The selected text is highlighted while the copy shortcut is held, then returns to normal when the keys are released.

For mouse or menu-based copy actions, Copy Highlighter uses a short configurable fallback duration because there is no keyboard release event to observe.

Settings

Open Settings -> Community plugins -> Copy Highlighter to customize:

• Highlight color
• Editor opacity
• Rendered text opacity
• Corner radius
• Whether rendered Markdown text is highlighted
• Mouse/menu copy duration
• Lost-keyup fallback duration

Privacy and permissions

Copy Highlighter runs entirely inside Obsidian. It does not collect data, send network requests, read your clipboard contents, or access files directly.

Development

Install dependencies:

npm install

Build once:

npm run build

Watch for changes during development:

npm run dev

Obsidian loads community plugins from .obsidian/plugins/<plugin-id>. The folder name should match manifest.json's id, and Obsidian expects the built main.js, manifest.json, and optional styles.css at that folder root.

After changing manifest.json, restart Obsidian so it re-reads the plugin metadata. After changing TypeScript, rebuild and reload the plugin.

Release files

Each GitHub release should include these assets:

• main.js
• manifest.json
• styles.css

The source TypeScript is for development; Obsidian loads the bundled main.js.
