I'm trying to learn Emacs, and I've installed MELPA as a package manager. The only problem is that the only way I know how to exit MELPA is by quitting Emacs entirely. I'm sure there's a better way to do this. What is it?
Killing buffers with C-x k RET is generally good advice, but it is much easier to quit the package-list-packages screen by simply pressing q.
This also works to exit dired buffers, magit, and many other types of buffers that aren't text-oriented.
