@ntnsndr I use Emacs only in the terminal. I encounter some broken stuff. But it's fine.
Keyboard handling in traditional terminals has limitations, although there are modern terminals that can address this ( https://sw.kovidgoyal.net/kitty/keyboard-protocol/ ).
(The main issue I believe is that you might not have all modifiers; I've had some issues due to lack of Super with some plugins. But the Spain keyboard layout causes me more issues :D)
