I've found it crucial to have Control mapped to the keys immediately next to and on both sides of the spacebar. Thumbs are stronger than pinkies for modifying keypresses.
Yes, that's a good idea since Control is the most common keybinding modifiers, so helps in other apps as well (likewise, using Cmd on a Mac would be preferable to using the literal Control)
Unless you change those as well
> All to say: learning emacs movement keys pays off.
It can also cost you RSI, so not worth it
