I read about this method of changing key mappings of your keyboard layout in the /usr/share/X11/xkb/symbols/ directory. I think this is basically what you do. In these files there are only symbols and “partial alphanumeric_keys” defined. I don’t see how keys like backspace can be redefined there. But I will look further into it.

I agree with the picture, but not the title. Nonviolent action is an option and was successful many times. Contingent on the situation, it can be more effective.

Better ditch this crap and use AWK for manipulating tables. It has all the intelligence you’ll need.
