Describe the background of your feature request

In order to optimize usability it should be possible to navigate to and through the documentation search (results) by keyboard.

Describe your idea

The idea is to let open the documentation search modal via keyboard by command + k.
Moreover, one should be able to navigate with arrow keys through the search result list without losing focus in the search input field.

Are there any workarounds or alternatives?

Not for keyboard.
