==Description==

The '''Std Undo''' command undoes the last action.

==Usage==

# There are several ways to invoke the command:
#* Press the {{Button|[[Image:Std_Undo.svg|16px]] [[Std_Undo|Undo]]}} button.
#* Select the {{MenuCommand|Edit → [[Image:Std_Undo.svg|16px]] Undo}} option from the menu.
#* Use the keyboard shortcut: {{KEY|Ctrl}}+{{KEY|Z}}.

==Options==

* To undo multiple actions click on the small black down arrow to the right of the {{Button|[[Image:Std_Undo.svg|16px]] [[Std_Undo|Undo]]}} button and select from the list.

==Preferences==

See also: [[Preferences_Editor|Preferences Editor]].

* The Undo/Redo functionality can be disabled by unchecking the {{MenuCommand|Edit → Preferences... → General → Document → Using Undo/Redo on documents}} option. But this is not recommended.
* The maximum number of Undo/Redo steps is controlled by {{MenuCommand|Edit → Preferences... → General → Document → Maximum Undo/Redo steps}}.

==Scripting==

See also: [https://labrps.github.io/SourceDoc/ Autogenerated API documentation] and [[LabRPS_Scripting_Basics|LabRPS Scripting Basics]].

To undo the last action use the {{incode|undo}} method of the document object. Its counterpart, the {{incode|redo}} method, is also available.

{{Code|code=
import LabRPS

LabRPS.ActiveDocument.undo()
}}

When running LabRPS in pure console mode (CLI), the undo/redo mechanism isn't enabled by default. It must be explicitly activated for each document.

{{Code|code=
import LabRPS

LabRPS.ActiveDocument.UndoMode = 1
}}
