keycap: *

*️⃣ is the "keycap: *" emoji, derived from the asterisk key on telephone or calculator keypads. Officially, it represents the asterisk symbol, commonly used for multiplication, annotation, or as a wildcard. In internet culture, it often serves as an emphasis marker, similar to "key point" or "note this," and sometimes indicates hidden or sensitive information (like passwords). Emotionally, it conveys a formal, technical, or alert tone, frequently seen in contexts requiring notation or highlighting.
