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

Use xkeycaps to look at your keyboard mapping and swap the META and ALT modifiers, or just swap the entire keys. Because GNOME has some assumptions about which keys have META and ALT modifiers, it'll probably make your life easier to swap the keys entirely.

xkeycaps should be available as an ubuntu package.
