org-use-extra-keys

org-use-extra-keys is a variable defined in `org.el'.
Its value is

nil

Documentation:
Non-nil means use extra key sequence definitions for certain commands.
This happens automatically if you run XEmacs or if `window-system'
is nil. This variable lets you do the same manually. You must
set it before loading org.

Example: on Carbon Emacs 22 running graphically, with an external
keyboard on a Powerbook, the default way of setting M-left might
not work for either Alt or ESC. Setting this variable will make
it work for ESC.

You can customize this variable.
