I have been trying to figure this out for a long time. I have a pretty typical Mac OS provisioning script:

I would like to change the Mission control shortcuts to all be Ctrl + Alt + ... instead of Ctrl + .... For example, the default is: Ctrl + Up to activate Mission Control. I would like to change this to Ctrl + Alt + Up, because the current shortcut conflicts with other programs I use.

Note that I am already aware of how to do this through System Preferences > Keyboard > Shortcuts, I am looking for a scriptable, command line solution.

Thank you!
