1. Install the extension
Add CopyButton from the Chrome Web Store and pin it to your toolbar.
2. Create a rule
Open a page, pick the value you want and define how CopyButton should find it. Use the visual picker, a CSS selector or XPath.
3. Choose the copied value
Copy full text, extract a match with regex or format the result with a template.
4. Save and reuse
Save the rule for that domain. When a matching page loads, the copy control is ready again.
Tip for dynamic websites
Choose stable attributes or nearby labels instead of generated class names. Test rules on several records.
