Explanation
Publisher actions, macros, and quick text are Salesforce productivity features that can help reduce the clicks a customer support agent uses when working on a case. Publisher actions are buttons that let you create records or perform tasks from the feed or record page. Macros are sets of instructions that tell Salesforce how to update fields, send emails, and perform other tasks on a case. Quick text are reusable messages that you can insert into emails, chats, tasks, events, and more. Verified References: Sales Cloud Productivity Best Practices
