Repeat Last Action Keyboard Shortcut
Press F4 on Windows (or Ctrl+Y) and ⌘Y on the Mac to repeat whatever you just did.
| Action | Mac | Windows | |
|---|---|---|---|
| Repeat last action | ⌘Y | F4 | |
| Repeat (alternate) | ⌘Y | Ctrl+Y | |
| Redo (after undo) | ⌘⇧Z | Ctrl+Y |
Do it again, instantly
Just applied a border, inserted a row, or changed a font? Press F4 (Windows) or ⌘Y (Mac) and the same command runs again wherever your cursor is now. It saves dozens of clicks when you apply the same change to many places.
Repeat vs. redo
Repeat applies your last action again; redo reverses an undo. In Windows apps Ctrl+Y often does both depending on context, while F4 is the dedicated repeat key in Word and Excel.
FAQ
What does F4 do in Word and Excel?
F4 repeats your last action — for example reapplying the same formatting, border, or inserted row — without redoing the menu steps.
What is the repeat shortcut on a Mac?
⌘Y repeats the last action in most Microsoft Office apps on the Mac.
Is repeat the same as redo?
No. Repeat runs your last command again; redo (Ctrl+Y on Windows, ⌘⇧Z on Mac) re-applies something you just undid.
