xselect2copy by 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:
