In long dropdowns or selects, users want to type a few characters to jump to an item (e.g., typing "j" jumps to "John"). Without this, they have to scroll endlessly or use the mouse.
Buffers keystrokes, matches them against item labels (case‑insensitive), and scrolls to / selects the matching item. Resets the buffer after a short timeout (default 500ms).
