In Emacs, when you press M-y, you can go through all the recent text snippets that are stored in your kill ring (aka “clipboard” in modern-day programs) via yank-pop. In two seconds, I found what I needed from yesterday, and I’m ready to go.
Emacs is just like that, once you learn to use it. Two seconds, you get what you need (for me, usually in org-mode), and you move on with your life. Everything is tailored to fit you, the user. That’s what happens when a bunch of productivity geeks sit together and build a program.
Sure, not all (and even most) programs that are open source end the same way, but Emacs is unique. It’s a shining example of what happens when different people have different needs and are provided with open tools to answer those needs. I’m not a Lisp coder, but I know that when I need to change something or tweak it, I can, and I have all the help documentation and a community behind me to help achieve what I need.
