The ARIA Authoring Practices Guide suggests including similar functionality:
- Type-ahead is recommended for all trees, especially for trees with more than 7 root nodes:
- Type a character: focus moves to the next node with a name that starts with the typed character.
- Type multiple characters in rapid succession: focus moves to the next node with a name that starts with the string of characters typed.

Until this is implemented, it should be possible to jump to a notebook using the Go to Anything dialog (opens with ctrl-p on Windows/Linux). From the Go to Anything help text (emphasis added),
Type a note title or part of its content to jump to it. Or type # followed by a tag name, or @ followed by a notebook name. Or type : to search for commands.
