Common uses
People use it when accepting a task, showing respect, saying goodbye, supporting a plan, or reacting to something honorable or difficult.
Tone in chat
It can sound formal in a funny way, as if the sender is saying "yes, captain." It can also be genuinely respectful in serious contexts.
For agreement without the formal tone, a check mark or thumbs up may be simpler.
