Adds APG type-to-focus search to a collection: printable keystrokes are buffered (resetting after a pause), and the first item whose label starts with the buffer is reported through onMatch. Pressing the same letter repeatedly cycles through the matches rather than filtering deeper. It moves nothing itself; pair it with the collection's own focus management, most often useListFocus or useGridFocus.
