# Collision detection ## What is Collision Detection? Keeping will display a notification if two agents are viewing a ticket at the same time. And if one agent attempts to reply to a ticket while another agent is composing a reply, Keeping will politely block the second agent. This prevents a customer from receiving multiple replies to the same message. ## When Multiple Agents are Viewing a Ticket If more than one agent is viewing a support ticket, Keeping will display a notification to each agent that others are viewing the same ticket. ![Get notified when multiple agents are viewing a ticket.](https://1058495162-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FCHa8WIsJ5Z5NqmPmq5VS%2Fuploads%2Fb75B6nEnRapjSvrUHeEx%2FAgent%20Viewing%20Ticket.png?alt=media\&token=1bbadc75-3466-4560-99d4-9ec38852a2a7) ## When Another Agent is Composing a Reply If a second agent attempts to start a reply when another agent is already composing a reply, Keeping will display a notification to the second agent. This notification can be dismissed by clicking the "Unlock" icon. ![Another agent is working on the reply. Click Unlock to proceed anyway.](https://1058495162-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FCHa8WIsJ5Z5NqmPmq5VS%2Fuploads%2FWi0UGoYlXXTqaIPmpCMs%2FCollision.png?alt=media\&token=5b08c83d-a900-4bb1-9314-40e9a1a464b1) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
