How can you tell worksheets are grouped?

Worksheets are grouped in spreadsheet applications like Excel when they are visually indicated by a different color on the tabs or when multiple tabs are highlighted simultaneously. You can also tell they are grouped if actions performed on one worksheet, such as formatting or data entry, are reflected across all grouped worksheets. Additionally, the status bar may display a message indicating that multiple sheets are selected. To ungroup, you typically need to click on a single worksheet tab.
