Undo/Redo Operation

To undo the last operation in a data entry form:

Click the Undo button in the quick access toolbar.
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 quick access toolbar.
Press CTRL+Y.

The Undo and Redo buttons are available:

On entering data to cells.
On data formatting.
On pasting/deleting data.
On autofill of cells with data.
On adding/deleting cells.
On creating/editing formulas.
On executing operations with rows/columns, except for freezing rows/columns.

On refreshing a data entry form and calculating algorithms for saving, the operations history is cleared, and the Undo and Redo buttons become disabled in the main menu.
