How do I remap META to ALT?

Question

I am using emacs in Ubuntu. How can I remap META to the ALT key?

Answer 1

If you run emacs in a gnome-terminal, the gnome-terminal may be capturing your alt key to open the gui menu (File, Edit, ...). You can change this behavior by selecting Edit >> Keyboard Shortcuts ..., and unchecking `Enable menu access keys ...'.

On my system, Ubuntu 9.04, this lets alt serve as meta for emacs.
