Capability to revoke your own API keys?

Is there the capability to revoke/regenerate your own API key? That way if you're dumb and (for instance) publish your API key on GitHub as you push your project, you can get ahead of it getting slurped up.

If not, can this be added? It'd be a good idea for security.

@anaerin: I'm not sure if this is publicly available as there are some security concerns with scrapers and other people who might get legitimately timed out on their API calls. But if you email support we can do this for you.
