I'd like to be able to order coffee from within my word processor!

I think you need emacs for that.

To be fair, you could use emacs to order coffee.

Or any other programmable text editor, Atom, Sublime to name two

There's a world of difference between "could" and "can", which is why I use Emacs and do things, instead of using something else and wondering what could have been ;).

Exactly.
