What shortcut can you use to insert the current date into a spreadsheet?

To insert the current date into a spreadsheet, using Ctrl + ; (semicolon) is the appropriate shortcut. This combination directly inputs the current date into the selected cell, which is particularly useful for logging or tracking data.

The other options do not correspond to the function of inserting the current date. Some shortcuts might perform different actions, like duplicating data or accessing other features, but they are not designed for date input. Thus, using Ctrl + ; is the most efficient way to achieve this specific task in spreadsheet applications.
