Features

• Copy reference: Copies @relative/path:line or @relative/path:start-end to clipboard
• Auto-focus & paste: After copy, automatically focuses and pastes into the target AI chat panel
• Target options: Claude Code, VS Code built-in Chat, or clipboard-only (none)
• No selection: When nothing is selected, copies the current line reference
• Shortcut: Ctrl+Shift+C (Mac: Cmd+Shift+C)
• Context menu: Right-click in editor → Copy/Paste section

Usage

1. Select a code block, or place cursor on a line
2. Press Ctrl+Shift+C
3. The reference is copied and pasted into the configured AI chat input

Note: Claude Code may auto-convert @file:line to @file#line. Both formats point to the same lines.
