shr-copy-url
shr-copy-url is an interactive compiled Lisp function in `shr.el
'.
(shr-copy-url &optional IMAGE-URL)
Copy the URL under point to the kill ring.
If IMAGE-URL (the prefix) is non-nil, or there is no link under
point, but there is an image under point then copy the URL of the
image under point instead.
If called twice, then try to fetch the URL and see whether it
redirects somewhere else.
