There are two keyboard shortcuts for redoing an action previously undid in Microsoft Office. The most commonly used shortcut is the combination of the "Ctrl" key and the "Y" key. Hold these two keys at the same time to redo something. Pressing the "F3" key is the second method.
It is possible to redo an action multiple times. This can be used to fill in fields when the data remains the same. Although they are not keyboard shortcuts, the undo and redo arrow icons in the top, left corner of the screen have the same effect. There is a drop-down box available for the undo arrow, allowing different things to be undone.
