What key allows you to redo an action in Excel?

The key combination that allows you to redo an action in Excel is Ctrl + Y. This function is important because it enables users to reverse their last undo action. For instance, if you mistakenly remove a change that you wanted to keep, using Ctrl + Y allows you to bring that change back without having to redo the action manually.

This is especially useful in spreadsheet work, where various manipulations or edits can easily be undone with Ctrl + Z, but in situations where you need to reinstate an action you just undid, Ctrl + Y serves to streamline your workflow and enhance productivity.

The other key combinations have different functions. For instance, Ctrl + Z is commonly associated with undoing actions, Ctrl + R is typically used for filling data to the right, while Ctrl + U is used to underline text in Excel. Understanding these different shortcuts can greatly improve efficiency when working with spreadsheets.
