Which key must be pressed in COSS to save changes?

In the COSS system, pressing F6 is the designated key for saving changes. This functionality is essential for ensuring that any modifications made within the system are securely recorded. Utilizing F6 allows users to confirm their changes and prevent potential data loss that could occur if modifications are not saved properly.

The other function keys serve different purposes within the COSS environment. For example, other function keys might be utilized for navigation or specific operations, but none of them fulfill the task of saving data like F6 does. Understanding this key assignment is crucial for users to efficiently and effectively manage data changes within the system.
