Yeah it hooks into some blocking event that gets called on every keypress. At least that's how it worked last time I tried it many years ago. Very sluggish.

Fortunately standard editing shortcuts like Ctrl-D, Ctrl-left/right, etc. replace 99% of Vim "magic" and are way easier to remember and use.

No offense, but if you think ctrl-shortcuts are easier to use you don’t really get the appeal of vim
