Copy Rich URLs is a powerful extension that will let you save links in your clipboard. It supports a wide range of formats, including HTML, Markdown, and even Text. All you have to do is click on the extension's icon, and it will copy the link to the clipboard. You can then paste it anywhere you want, even into a Google document. The only requirement is that the link is valid and doesn't have any harmful intent. You can save it in a variety of styles, too.

It's a very handy tool, especially for people who use Google documents or any other service that lets you paste links into a text field.
