xselect2copy от MJduDA

xSelect2Copy is a lightweight browser extension designed to streamline text copying on web pages. Instead of the traditional right-click and "Copy" process, this extension allows you to copy text selections simply by holding down a modifier key (Ctrl, Shift, or Alt) while highlighting the text with your mouse.

Key Features:

Instant Copying: Hold Ctrl, Shift, or Alt while selecting text to copy it directly to your clipboard
Cross-Platform: Works on Windows, macOS, and Linux
No Interference: Doesn't modify page content or interfere with website functionality
Customizable: Configure which modifier keys trigger the copy action in the extension options
Privacy-Focused: No data collection or tracking; operates entirely locally
How It Works:

Install the extension
Select text on any webpage while holding Ctrl (or your configured key)
The selected text is automatically copied to your clipboard
Paste anywhere as usual
Use Cases:

Quick copying of quotes, code snippets, or important information
Efficient research and note-taking
Streamlined workflow for content creators and developers
Accessibility improvement for users who prefer keyboard shortcuts
Privacy Policy:

This extension does not collect, store, or transmit any personal data. It operates entirely within your browser and only accesses the clipboard when you explicitly copy text using the extension's functionality.
