I read a lot of answers online that its a bad idea, but the arguments did not make a lot of sense. “it’s a heavily ingrained part of the eco system”. Well if I can change it, what’s the deal?
It makes more sense to make an interrupt signal be the harder shortcut, and copy to be ctrl+C, matching other programs and platforms.
The “why” doesn’t matter. If you don’t like it, change the shortcuts on your own machine. That’s the beauty of Linux.
