Over at the Emacs subreddit, BBSnek writes about discovering remember mode. It’s been around for a long time. I remember using it before Org mode. Indeed, I still use Ctrl+c r to invoke org-capture because that was what I was used to with remember-mode.
Although I’m sure there are some, I can’t think of any reason to use remember-mode these days. Org mode can do everything it can and more. Org’s templates make capturing data and notes so much easier and, of course, you can bring all the other Org tools to bear on the results.
BBSnek uses it for quick notes—and it’s great for that—but Org can do that too and so much more. The truth is, I’m surprised that anyone is still using it for any other reason than inertia. Still, as usual, Emacs lets us have it our way and for those who prefer the simpler and lighter weight remember-mode, it’s there for them.
