How to kill the buffer in emacs without being questioned.
5 Answers
Use (kill-current-buffer) instead of (kill-this-buffer) if you want to bind it to some key. See the docs for (kill-this-buffer)
...
This command can be reliably invoked only from the menu bar, otherwise it could decide to silently do nothing.
and (kill-current-buffer)
...
This is like ‘kill-this-buffer’, but it doesn’t have to be invoked via the menu bar, and pays no attention to the menu-bar’s frame.
So I would put the following in my init.el:
(global-set-key (kbd "C-x k") 'kill-current-buffer)
This works at least in emacs 26.1.
