Which of the following shortcut key is used to repeat the last command or action, if possible, in MS-Excel 365?

  1. A.Ctrl + Z
  2. B.Shift + Z
  3. C.Ctrl + Y
  4. D.Shift + Y

Correct answer

C. Ctrl + Y

Explanation

The correct answer is C, Ctrl + Y. In MS Excel 365, Ctrl + Y repeats the last command or action wherever repeating it is possible, so if you have just made a cell bold or inserted a row, pressing Ctrl + Y does the same thing again at the new position. It also works as Redo, undoing an undo, because Excel treats the two as one key. The function key F4 does the same repeat job in Excel, which is why it is popular for copying formatting down a sheet. A is wrong because Ctrl + Z is Undo, which cancels the last action instead of repeating it. B is wrong because Shift + Z is not a command shortcut in Excel; it simply types a capital Z. D is wrong because Shift + Y likewise only types a capital Y. Exam tip: Ctrl + Z undo, Ctrl + Y redo or repeat, Ctrl + C copy, Ctrl + V paste, and F4 also repeats in Excel.
