Then why using a TUI editor at all? Each time nano was opened because of some default settings, I saw this whole bottom bar with shortcuts. It sure doesn't seems to be easy to learn either.
Software engineers that went to college have taken Calculus, Physics, and other advanced courses that can be very hard for many to learn.
The reality is that memorizing a few keyboard shortcuts is not in fact hard. It’s something that can take time, and you might not like the shortcuts, but it’s not hard.
If you want to use powerful tools, you’re going to have to learn how to use them. There’s no way around this.
Not to mention, some of that dev group prefer that their small editor have the same keybindings as their full dev environment and entire OS for that matter. No mode switching needed.
Sounds easier than not seeing a bottom bar with shortcuts.
