It is a new Safari extension that allows you to copy the URL of the web page displayed in the currently active tab to clipboard in various formats such as HTML, Markdown, Rich Format (RTF), and text of the title and URL. 

It is very easy to use!
After viewing a web page in Safari, right-click (click on the secondary button), and from the context menu that appears, select the "Copy Link to Pasteboard" drill-down menu and choose formats you prefer.
Then, simply paste it into your text editor or application!

# Permissions will be required the first time you use it.
