Question

When calling switch-to-buffer, in the minibuffer, when you press SPACE, you can see hidden buffers that you normally don’t see, like *Minibuf-0* for example.

How could you list those hidden buffers into the list of buffers shown by list-buffers ? If it’s not possible using list-buffers, how do you manage them ?

Answer 1

You can tweak the function to show all buffers, like so:

(defun list-all-buffers (&optional files-only)
  "Display a list of names of existing buffers.
The list is displayed in a buffer named `*Buffer List*'.
Non-null optional arg FILES-ONLY means mention only file buffers.

For more information, see the function `buffer-menu'."
  (interactive "P")
  (display-buffer (list-buffers-noselect files-only (buffer-list))))

(define-key ctl-x-map "\C-b" 'list-all-buffers)
