Especially on smartphones it would much easier to edit text and navigate with Vim bindings. I think the Ace Editor and Codemirror support Vim bindings.
Could you open an issue here ( <a href="https://github.com/AntouanK/hni-ui/issues" rel="nofollow">https://github.com/AntouanK/hni-ui/issues</a> ) with a small proposal of how that would work?
I'm re-writing in Elm the front-end for my HN app, so that would be an interesting feature to add.<p>Edit: I thought you meant navigating the site. You only meant the text editing part though, right?
