We do similar, also with "c" meaning "clarification needed", and it's higher priority than a hand or a question. When there's a "c", then the speaker pauses ASAP to out what needs clarifying. These are important to ensure the context is correct and understood by participants. For visual meetings, a person can indicated "clarification needed" by raising their hand while making a "c" shape.
