Several Undo functions are available from the Edit menu. The option that is displayed is determined by the most recent Edit operation that you performed:
Negates the preceding Cut operation.
Negates the preceding Copy operation.
Negates the preceding Paste operation.
Negates the preceding Paste Next operation.
Negates the preceding Clear Fields operation.
Negates the preceding Copy Append operation.
Negates the preceding Copy as Table operation.
Negates the preceding Copy All operation.
Negates the preceding Undo operation. This restores the prior Edit operation that you performed.
For example, if you selected Clear Fields, then selected Undo Clear Fields, the Undo Undo operation would restore the Clear Fields action.
If no operation can be undone, then Undo is shown as unavailable from the Edit menu.
To disable the Undo functions, you must disable the Cut/Copy/Paste options. See Disable Functions: Others for details.
