About This Shortcut
This shortcut will allow multiple levels of redo’s; each time you use it Excel will step forward one level. Also, with certain actions (e.g. deleting a row), Excel will perform that action again. So, in some cases you can use this shortcut to quickly perform the same action again multiple times.
On Windows, F4 also works.
