Someone made a comment and deleted it that I’ll reply to here for them. One of their complaints was about spaces vs tabs and having to smash arrow keys. I’m about to blow your mind (definitely blew my mind ages ago when I first learned about it): Windows/Linux: Ctrl+arrow Mac (rarely apps do ctrl but usually you can remap): Alt+arrow This jumps words and will let you get around your lines much, much faster. Of course…
I use vim and thus repeatedly pressing directional keys has never been my primary concern. That said, I use tabs.
