This is where vim keybinds fall short every time. I do appreciate the effort, and have zero expectations about a one to one match, but the moment I do something out of habit and an editor doesn’t do what I expect, in “vim mode”, it breaks the illusion.
Honestly most implementations are just the basic navigation keys and a couple of edit commands. The basic navigation in Helix is the same as Vim so the ubiquitous feeling continues.
