;;; Commentary:
;;
;; Provides a function `switch-to-previous-buffer' and a minor-mode
;; keymap for binding this function to.  There is no current
;; default-binding.

;;; Code:


(defun switch-to-previous-buffer ()
  "Switch to previously open buffer.
Repeated invocations toggle between the two most recently opened
buffers."
  (interactive)
  (switch-to-buffer (other-buffer (current-buffer) 1)))


;;;###autoload
(define-minor-mode switch-to-previous-buffer-mode
  "Toggle Switch to Previous Buffer mode.
This mode provides a binding to invoke `switch-to-previous-buffer`."
  :init-value t
  :lighter nil
  :keymap (make-sparse-keymap)
  :global t
  :group 'switch-to-previous-buffer
  :require 'switch-to-previous-buffer-mode)


(provide 'switch-to-previous-buffer-mode)
