Associating a region with a link

Associating a region with a link

[Nordlöw]

How do I make a buffer-region become a link which is followed by
clicking on it like in grep-mode. How do I change the color of a
region?

There are many ways. One of the easiest is perhaps using buttons (for
example insert-text-button).

I think the most comfortable way is the 'button package.

(define-button-type 'my-button
  'follow-link t
  'action 'my-action
  'help-echo "mouse-2, RET: Jump...")

(defun my-action (button)
  (goto-line (button-get button 'my-target)))

(let ((beg (point)))
  (insert "link")
  (make-text-button beg (point) 'type 'my-button 'my-target 25))

You can change the color by setting the 'face property.
