The User:Isaacl/script/copy-comment-link-to-clipboard script provides a way to copy link wikitext to the clipboard that links to a specific discussion comment, or to a heading.

• The target text </> is prepended to the start of each comment. Clicking on it copies a wikitext link for the comment to the clipboard in the format used by mw:Talk pages project/Notifications. Thus when the link is followed, the linked comment will be highlighted.
• Headings will also have <h/> prepended. Clicking on it copies a wikitext link for the heading to the clipboard in the format used by the table of contents.

A popup with the wikitext link is displayed when the target text is clicked.

Note the text copied to the clipboard does not contain surrounding square brackets: [[ ]]

To install, you can use the script installer gadget, or add the following text to your common.js file:

mw.loader.load('https://en.wikipedia.org/wiki/User:Isaacl/script/copy-comment-link-to-clipboard.js?action=raw&ctype=text/javascript', 'text/javascript');

A "Toggle link2clipboard" item is added to the tools menu. Clicking on it will display the targets to copy the link wikitext. Clicking again will clear the targets.

Browser support

Based on MDN's "Interact with the clipboard" page, this script supports all browsers categorized as Grade A by the MediaWiki development team except Safari and Safari on iOS.

On Safari browsers, the wikitext link will not be copied to the clipboard automatically. Instead, it can be manually copied manually from the popup.
