Undo or Redo an action in Excel
To undo an action press Ctrl+Z. You can remember it from the German word: Zurück.
Fortunately, this shortcut is universal, so you can use it in other programs as well. For example, Word, internet or Gmail.
I beleive in shortcuts, but if you prefer your mouse, click Undo on the Quick Access Toolbar. I keep the Quick Access Toolbar for other icons.
