I thought of doing this in the beginning. The problem is there are so many places this will fail. Applications built for mac will assume you have the default layout. For starters, ctrl+c won't work: it needs to be ctrl+c for terminal for keyboard interrupt signal.

Actually, in Linux, most terminals support ctrl+shift+c/v for copy & paste.

I think the point here is: I try to stick to system default wrt to shortcuts, otherwise you'll spend a lot tweaking every application, and the ones you're yet to use.
