How to force Emacs not to display buffer in a specific window?

Question

My windows configuration looks like this:

          +----------+-----------+
      |          |           |
      |          |           |
      |          |         


        

Answer 1

Perhaps something like this could work:

(defun display-buffer-avoiding-lr-corner (buffer &optional not-this-window)
  (save-selected-window
    (when (buffer-file-name buffer)
      (select-window (window-at (- (frame-width) 1)
                                (- (frame-height) 2))))
    (let ((display-buffer-function nil))
      (display-buffer buffer not-this-window))))

(setq display-buffer-function 'display-buffer-avoiding-lr-corner)
