How to remove Alt+Tab and CMD+A keys?

[Juan Carlos]

I have the doubt How to remove Alt+Tab and CMD+A keys? because if you make a blocker, you can remove the touch and work of ESC, Ctrl+C, but in Windows Alt+Tab and Amiga systems CMD+A these key combinations continue working and is possible jump to system and the blocker does not do its job. some idea how to cancel these combinations?
Thanks for the suggestions.

Sorry, it's not possible to intercept those system keys. Hollywood is not designed to create apps that will lock up your system

Thank you for your answer, and in a next version can you add to Hollywood? because besides to useful to make a locker, is useful to make portable screen savers, etc.

Sorry, I don't think that is even possible for normal apps. This requires special privileges as a malware precaution.
