Type the command in lobby chat, including its leading dot: .queue, .style jack, or .pp HD HR 99.2. Command names are case insensitive. Arguments depend on the command; do not assume every command accepts percentages or a username.

Start with .help and .help2. The in-lobby response reflects that room's mode and your permissions. The wiki command index groups commands by purpose and gives exact examples.

Check the spelling, lobby mode, and whether you are a player. Rapid repeated commands can be silently throttled. Staff can temporarily disable public commands during busy periods; privacy controls remain available. Wait before retrying. See command troubleshooting.

Skip, replay, and difficulty commands are votes rather than personal settings. Mania style selections affect future picks for the shared room. Coordinate with other players rather than repeatedly sending the same command.
