I daily drive Linux mint. I can’t use ctrl+C in the terminal for Copy because that’s reserved for the interrupt signal. Fine - I’ll use meta+C. But I can’t use meta+C to copy in IntelliJ because the meta key isn’t a modifier key in Java. I’ve ended up needing to memorise different keys for copy+paste in every program I use. I mess it up on a daily basis. It’s madness!
Linux is like that everywhere. I like smooth scrolling. Some applications support it properly. Some half support it, or add scrolling lag for no reason (Firefox) and some break completely, assuming every scroll event should scroll a few lines down. I eventually solved my software problems by buying a worse mouse without smooth scrolling support.
Alt+mouse drag moves windows around. I love that feature! I can’t believe windows and macOS are missing it! But - oops. Alt+click is a thing in davinci resolve for adding keyframes. Urgh. It’s this. Over and over again constantly.
