Be careful when using groups because if you forget that your spreadsheets are grouped and then proceed to add or change figures on a worksheet, all of the worksheets in the group will have the same figures. To remove a group, simply click on a sheet that is not in a group. If all of the worksheets are grouped, right_click on any tab and choose Ungroup Sheets. Keep an eye on the title bar prior to making changes and Excel will tell you if the sheets are grouped.
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.
