ViHN: keyboard navigation for Hacker News 作者： Quentin Santos

Vi-style key bindings for browsing Hacker News.

It's fast. If you have to wait a perceptible amount of time, that's a bug.

Compatible with <a href="https://addons.mozilla.org/en-US/firefox/addon/hacker-news-night-mode/">Hacker News Night Mode</a>. See also <a href="https://addons.mozilla.org/fr/firefox/addon/vimium-ff/">Vimium</a>.

<strong>Features</strong>

Use the key bindings similar to Vi to navigate Hacker News stories and comments.
It should work on story listings (front page, /new, /newest, /best, user submissions, etc.), comment threads, and comment listings (user comments, etc.).

Also, you can quickly find new comments by hitting “n” to browse comments in inverse chronological order.

In addition, the quick-reply and quick-edit forms let you see a preview of the comment you are writing.

Finally, the original poster (OP) is highlighted in comments.

<strong>Key bindings</strong>

Press <strong>?</strong> to toggle help.

<strong>Note</strong>: Like in Vim mapping, case is important. So <strong>j</strong> means hitting the <strong>j</strong> key with <strong>Caps Lock</strong> disabled, and without holding <strong>Shift</strong>. But <strong>J</strong> means hitting <strong>j</strong> key with either <strong>Caps Lock</strong> enabled, or while holding <strong>Shift</strong>.
