After you create the group, the word "group" appears in the title bar of the workbook. Once they are grouped you can format one worksheet and all of the worksheets will have the same formatting. You can insert a row in a worksheet and the same row will be inserted into all worksheets. This is a great tool when you need for all of your worksheets to have the same formatting.
Easy Worksheet Management _ Right_click on any sheet tab (Sheet1, Sheet2, etc.) for a shortcut menu of worksheet options. This is a quick way to rename, delete, add, apply colors to worksheet tabs, copy, and more. By the way, you can also rename a worksheet by double_clicking on any sheet tab (Sheet1, Sheet2, etc.) to highlight the sheet name. Type a new name and press [Enter]. Tip: avoid ALL CAPS which increases the width of the sheet name and decreases how many worksheets can be displayed in one view.
