Escape destroys an already committed value.

Member previewVariant 4 · 3 implementations · 12 checks per implementation

Case contract

Escape discards query but preserves committed value; Enter commits only an existing active option in an open popup; Tab closes without commit; Clear resets both; typing opens suggestions.

Why this case matters

A deterministic model of combobox keyboard commit; this isolates one interface invariant without requiring a browser.

One recorded failure
