How do I map unmapped keys on a keyboard? [closed]

My laptop's keyboard has keys that don't do anything when I press them. How would I enable the keys, and add functionality to them?

For example, the mute key doesn't do anything at the moment.


You can use xmodmap. It's how I get my Zboard keys to work. For actual keys not media keys.


There's a keyboard shortcuts editor in System->Preferences.
