I added keyboard navigation for posts and comments to Lemminator. These hotkeys will feel familiar to Vim users.

Here's how it works:

• j goes down, k goes up
• For posts: o opens the post page
• For comments: l goes to first child comment, h goes to parent
• More posts/comments will load if you step over a page limit
• Esc ends navigation

Keyboard navigation pairs well with browser plugins like Vimium, allowing you to reach features that aren't explicitly navigable with familiar key bindings. Just make sure to exclude the above hotkeys from Vimium.
