Kill default buffer (with cursor)

Question

Windows 10, Emacs 25.1, Helm

I open 3 buffers (3 files). Show only 2 buffers.

As you can see the current buffer is my_buffer_1 because cursor is in this buffer. I want to kill this current buffer.

M-x kill-buffer

But Emacs ask me what exactly buffer I want to kill.

I select my_buffer_1 and press Enter. As result buffer is killed.

Is it possible Emacs to not ask me about buffer name and kill default (with cursor) buffer? In my case this is a my_buffer_1.

Answer 1

Use the function kill-this-buffer. I basically never want to kill buffers that are not the current buffer, so I rebind C-x k to that function:

(global-set-key (kbd "C-x k") #'kill-this-buffer)

(Of course, if you ever do wanted to be prompted for a buffer to kill, you can just run M-x kill-buffer, or since you use Helm, kill it from the buffer switcher.)
