switch-to-buffer doesn't work always?

[rnd]

Hello, elisp guru!

(I am new to Emacs - only 4 days using it.
My emacs is 20.3, Linux RH6.2)

The following code is from my .emacs file
(I did it myself)

--------------------
(setq mim-list ())
;;
(defun enter-file ()
  (interactive)
  (setq fn (thing-at-point 'filename))
  (find-file fn)
  (add-to-list 'mim-list fn)
)

;;
(defun return-from-file ()
  (interactive)
  (save-buffer (current-buffer))
  (if mim-list
     (switch-to-buffer (car mim-list))
     (save-buffers-kill-emacs)
  )
  (setq mim-list (cdr mim-list))
)

(global-set-key [(control c) down] 'enter-file)
(global-set-key [(control c) up] 'return-from-file)
---------------

i.

C-c Down is expected to enter file at the point and
C-c Up to return from the file (works recursively),
saving it but not killing the buffer.

C-c Down works fine but not C-c Up.
(In the first version of the code I saved not
the names of the files but bffers - with the same result)

I can't understand why return-from-file doesnt open old buffer!
(It saves is though)

ii.

And that is not the only problem!
I want to bind return-from-file to ESC Up and
enter-file to ESC Down, but Emacs doesn't allow this:

(global-set-key [ESC Down] 'enter-file)
(global-set-key [ESC Up] 'return-from-file)

- it just doesn't work for no reason!

------------------------------------

Any ideas? I will appreciate your help!


Sincerely yours, Roman Suzi
