I second this. I only started slowly switching to nvim few months ago, and I already can feel slightly annoyed when I have to take off my hands of the keyboard to reach for a mouse, or when I'm editting a text in i.e a browser, want to make an edit few words back, and I have to spam keys like a madman instead of just jumping where I need to be.
It's addicting and extremely comfortable, having a good keyboard navigation controls.
I really need to look into tiled window managers and a browser.
