You’ve got that command palette concept like sublime/atom/vscode. If it holds any weight, the user can navigate the palette items in all of those apps with ctrl+n and ctrl+p. I’m a vi guy myself, and use the vim plugin for editing, but in places where the vi modal style of editing doesn’t make as much sense (like the palette), I’d expect basic emacs key bindings to work so I can keep my hands off the trackpad and arrow keys when possible.
