If you extend this selection in any direction, you’ll see that the active cell doesn’t change.

Only the selection changes.

However, when you make a new selection, the active cell will update.

To move the active cell right, use tab.

And to move the active cell left, use shift + tab.

you might rotate the active cell through the 4 corners of your selection using Control + period.

This is a handy shortcut, as we’ll see in a minute.

On a Mac, the shortcut is Control + Option plus the right or left arrow.

Let me show you how working with the active cell can be helpful.

In this worksheet, we have a set of employee data, which is summarized by this pivot table.

you’ve got the option to see that we have data for 300 employees.

I don’t know whether the new data contains more or fewer employees.

This makes it easy for me to see and delete the extra rows.
