feat: key press of slash focuses search bar

[miketheman]

First time caller, hope I got it right.

Having used search on websites and loving the keyboard focus, and recognizing that autofocus can solve the issue, yet introduces accessibility concerns, I thought that adding the ability to implement to opt in to a method for surfacing the feature.

Happy to take some feedback, this isn't the most familiar code for me yet.

Hey @miketheman! 👋

These changes look all ok, though I will note that we're on the threshold of the 1.5.0 release, which brings an entirely new UI: https://ui.pagefind.app/

The existing "default ui" won't be removed, though it will become somewhat deprecated in favor of the new UI components.

Oh, that's very cool! Glancing at the docs, it doesn't look like there's an option in the new component style to have a single key press like slash, it must have a modifier?

Currently yep, but that can be adjusted :)

[miketheman]

Cool, I'll have to take a look. In the meantime, if this makes it in, we could start using it on the existing UI

Currently yep, but that can be adjusted :)

Challenge accepted - first commit on #1025 does that
