Frequently Asked Questions

What is the default keyboard shortcut for Redo in PowerPoint?

The default keyboard shortcut for the Redo command in Microsoft PowerPoint, as well as in WPS Presentation, is Ctrl + Y on Windows. Alternatively, the F4 key can also be used to repeat your most recent action.

Why does the Redo button appear greyed out?

The Redo button remains naturally greyed out and inactive until you perform an Undo action first. If it stays greyed out even after you undo a change, it usually indicates a corrupted software state, a conflicting third-party macro, or a system memory issue.

Will running an Online Repair delete my Office files or presentations?

No. Running a Microsoft Office Online Repair only replaces or fixes the core application installation files on your computer. Your personal presentations, documents, spreadsheets, and other user data will not be deleted or affected in any way.
