yeah Vim takes a lot of effort to learn. Like any advanced tool. I will 100% always fire up nano when in a hurry. but i like trying to learn Vim as an exercise (in torture? idk haha)
When I first installed a distribution where the base system only came with nano instead of standard editors, I was very confused (and very disappointed that this whas what they'd come up with as a "friendly" interface).
well, like the parent of my comment said, nano is a lot easier to use than vim or emacs. nano is much more like DOS edit or stuff like that. there are many memes about not being able to quit Vim, etc
The main things i learnt from vim are Escape :q and ^Z. Not a dig on vim, but it was quite a learning curve at the time when nano has been good enough for just about everything i do day to day.
