feat(docs): hotkey to jump to search box

[Hona]

for faster navigation of the docs site, pressing / from anywhere, or maybe Ctrl + K should jump to the search box.

Again, I'm happy to implement, just need confirmation :)

/ is probably dangerous when you will use some examples. But Ctrl+K could be added.

I think / is okay to add too. GitHub is using it now as a search shortcut as well

Hi Luke, Any update on this?
