Hallo, I want to globally use M- to cycle between buffers (using a function by Xah Lee). It works fine except when in Org-mode where this key is bound to org-complete in org.el. I have tried: (add-hook 'org-mode-hook (lambda () (define-key org-mode-map [(meta tab)] 'previous-user-buffer))) unfortunately, the original Org-mode setting prevails. What is going wrong? Many thanks in advance. Warm regards, Stefan -- Dr. Stefan Vollmar, Dipl.-Phys.
