Undo/Redo Operation

To undo the last operation in a report:

Click the Undo button in the main menu.
Press CTRL+Z.

If changed data was saved and then the saving operation was undone, previous values will be restored. Those values will be highlighted as changed and to further use them, save them.

To redo the last undone operation:

Click the Redo button in the main menu.
Press CTRL+Y.

The Undo and Redo buttons are available:

On entering data to cell.
On data formatting.
On pasting/deleting data.
On autofill cells with data.
On adding/deleting cells.
On creating/editing formulas.
On executing operations with rows/columns, except for freezing rows/columns.
On adding, deleting, moving a chart, shape, and image.

After a report is refreshed, operations history is cleared, and the Undo and Redo buttons in the main menu become disabled.
