How to replace a piece of text in Emacs with a link or reference?

Question

When writing emails with Emacs, I like to use this format with numbers between square brackets to point to URLs. Example: The first version [1] is still buggy, so I have downloaded SomeAlternative [2] instead. [1]: http://blahblahblahblah.com/version1 [2]: http://gaaaaaaaah.com/ Is there any Emacs mode or key sequence that allows me to quickly replace a URL with a reference in this format ?

Accepted Answer

There is the genuine `footnote-mode` minor mode.
