Wasn't present on the old website, would be nice to have
/ (slash) and Ctrl + K + ⌘ - to open the search, we can support both options, second seems more "preferable"
↑ / ↓ - navigate up and down through the search results
Enter - select the current search result
Esc - close search
Tab / Shift + Tab - navigate between search results (they should be "tabbable", for now the search closes when we change the focus from search to the next element with the Tab key)
