Question

I suppose my problem is pretty obvious, but I don’t know Lisp and can’t figure it out. Every time I try to write a capital “M” in a python file it won’t work (It seems to think that’s a start of a shortcut). My guess is that’s somewhere in a module or my .emacs file it tries to bind something to Alt + something. But instead it binds it to capital M something. Here’s my .emacs file (of which I copied most of it from the net):

; load-path setting is only needed if the directory you put
; weblogger.el in isn't already in your load-path
(add-to-list 'load-path "~/.emacs.d/")

; Remap Ctrl-tab to M-Tab

; (load-library "init_python")

Any idea where I should start looking for the problem? A simple search or any other way to debug the files in the .emacs-directory?

Answer 1

This looks wrong to me:

(define-key py-mode-map (kbd "M-") 'anything-ipython-complete)
(define-key py-shell-map (kbd "M-") 'anything-ipython-complete)
(define-key comint-mode-map (kbd "M-") 'comint-next-input)
(define-key comint-mode-map (kbd "M-") 'comint-previous-input)

kbd expect a full binding, but you’re trying to bind M-
to some functions. I suspect a letter is missing.

i.e.

(define-key py-mode-map (kbd "M-TAB") 'anything-ipython-complete)

Here, M stands for META which is usually bound to ALT
or ESC.

By the way, you can do XC–h to see
minor mode bindings starting with X.
