The correct keyboard shortcut to cut a cell value in Excel is Ctrl + X. To use this shortcut, first select the cell or cells that you want to cut, then press and hold the Ctrl key on your keyboard and press the X key. This will cut the selected cell value and place it in the clipboard. You can then use the Paste command or the keyboard shortcut Ctrl + V to paste the value in a new location. Its worth noting that some sources suggest using Shift + Delete as the keyboard shortcut to cut a cell value, but this is not the correct shortcut.
