Kbd
A single key, rendered in a <kbd>. Render one per key and let them sit side by side.
Do not hard-code Ctrl. The same shortcut is ⌘ on macOS, and the server usually cannot tell which the reader is on; decide per platform in the page, or name the key generically.
.hui-kbd
A keyboard key.
<span class="hui-kbd">Ctrl</span>
