This almost works. This is what I initially tried to do. Just do a basic remapping of Control to Super in terms of key position. Then I tried to force my terminal to take Super-C, etc. to send the proper control sequence, and never succeeded. So, terminal windows and terminal applications became their own nightmare of special-casing, context-sensitive hell. My workflows bounce back and forth between lots of GUI stuff and terminal stuff, so I always have to be vigilant about what I'm copying from and what I'm pasting too. It's error prone and keeps me squarely out of fluid unconscious muscle memory speed-working. Remapping the position of Control to the Super key just shuffles the annoyance around, unfortunately. I tried to live with it for a few months.
