[Christopher Dimech <dimech@gmx.com>]

   I am tryong to set keybindings for dragging line backwards and forwards
   using
   org-def but emacs is complaining when I do "emacs  --debug"
   ( org-defkey org-mode-map (kbd "C-t l b") 'org-drag-line-backward )
   ( org-defkey org-mode-map (kbd "C-t l f") 'org-drag-line-forward )


   emacs  --debug
   Debugger entered--Lisp error: (void-function org-defkey)
