How can you use the Command field to open a new transaction in its own browser window while simultaneously?

To open a new transaction in its own browser window using the Command field, you can enter the transaction code followed by a specific command that indicates a new session. For example, in SAP, you would use the command "/o" followed by the transaction code (e.g., "/o VA01"). This will launch the transaction in a new window while keeping your current session active, allowing you to work on both simultaneously.
