Use goto-address-mode to make links in Emacs buffers clickable.
Org mode has this nice thing where you can click a link in the buffer to open it in your browser. Turns out that's not some special org-only behavior. It's goto-address-mode, a minor mode that activates URLs and email addresses in the current buffer.
You can manually launch it with M-x goto-address-mode. It might be easier to automatically enable it for certain modes. You do that with a hook.
I want links to be available when reviewing notes and blog posts. Since I write those notes in a number of formats, I should add the hook one of the general major modes. text-mode is a good start.
;; base mode for prose (add-hook 'text-mode-hook (lambda () (goto-address-mode)))
Now I can open links from my Markdown and RST files with a click! Or a C-c <RET>.
|C-c <RET>||goto-address-at-point||Opens the link under point|
I might add the hook for prog-mode later, if I find myself wanting to click URLs in source code.
