'Edit' 'Undo'

Shortcut: <Ctrl>+<Z>

This command undoes the action which was most recently executed in the currently-open editor window or in the Object Organizer; repeated use undoes all actions back to the time that the window was opened. This applies to all actions in the editors for POUs, data types, visualizations and global variables and in the Object Organizer.

With 'Edit' 'Redo'⮫ “'Edit' 'Redo'” you can restore an action which you have undone.

The commands Undo and Redo apply to the current window. Each window carries its own action list. If you want to undo actions in several windows, then you must activate the corresponding window. When undoing or redoing in the Object Organizer the focus must lie here.
