As an re-education procedure in order to reduce (likely) future data loss, I wish to disable the Shift+Del functionality to delete files in Ubuntu (11.10 and 12.04). Also, if I could replace it with a "Stop that!" popup alert, even better.
I know there are data recovery tools for such cases, but better never put my important data at risk due to such mistakes. And I found nothing similar around, so I hope someone here can show me how, if possible.
