What series of commands should you use when you want to duplicate data from one location in a worksheet and add it to another location?

To duplicate data from one location in a worksheet and add it to another location, you can use the copy and paste commands. Here's the series of commands:

1. Select the data you want to duplicate: Click and drag the cursor over the cells you want to copy.

2. Copy the selected data: Right-click on the selected cells and choose "Copy" from the context menu. Alternatively, you can use the keyboard shortcut: Ctrl+C (Windows) or Command+C (Mac).

3. Navigate to the destination location: Click on the cell where you want to paste the duplicated data.

4. Paste the copied data: Right-click on the selected cell and choose "Paste" from the context menu. Alternatively, you can use the keyboard shortcut: Ctrl+V (Windows) or Command+V (Mac).

5. The data will be pasted into the new location, duplicating the original data.

Note: If you want to paste the copied data in a different format or with different options, you can use the paste special command (usually available in the paste options menu) or explore other paste options provided by your spreadsheet software.
