When you want to enter multiple lines of text in a single cell, what key combination is used?

To enter multiple lines of text within a single cell in Excel, the key combination you would use is Alt + Enter. This command allows you to create a line break within the same cell, enabling you to format the text in a more organized manner. When you press Alt + Enter after typing a particular line, it moves the cursor to the next line within that cell, permitting you to continue entering text on a new line.

This feature is particularly useful when you want to display data in a more readable format, such as when listing items or creating structured text within a single cell. By using this method, you maintain the content within the confines of one cell rather than having to resort to using multiple cells.

In contrast, the other key combinations listed do not serve the purpose of inserting line breaks within a cell. For instance, Ctrl + Enter is used to fill multiple cells with the same data simultaneously, while Shift + Enter is typically used to move up one cell in a worksheet. Enter + Tab does not have a defined function in the context of inserting line breaks and would likely result in moving the selection to another cell instead.
