 If you want to perform operations on multiple worksheets, multiple tabs, you can make a group. We're going to start out. I'm going to make a group of these three tabs that are adjacent. If you had a lot of them, the quick way of doing that is to left click on the first one to make sure you select it. Hold down the ship key and then go to the end tab in that adjacent group and left click again. Now I've selected those three and made a group of them. If I wanted to add this tab which is not adjacent, I will hold down the control key and click on that. And now I've made a group of these four tabs. I can move that group together or I can right click on the group and change the tab color of all of those. I'm going to make a group of these four tabs.
