StrgZ

StrgZ is the German-language compact reference to the undo keyboard shortcut, usually written as Strg+Z. Strg stands for Steuerung, the German label for the Control key, and Z is the letter Z. Together, Strg+Z triggers the undo function in many applications on Windows and Linux systems.

When a user makes changes, invoking Strg+Z reverses the most recent operation; many programs maintain a history of actions that allows multiple steps to be undone in sequence. Undo is commonly available in word processors, graphic editors, spreadsheets, integrated development environments, and file managers.

There are variations: redo is often Strg+Shift+Z in many apps, or Strg+Y in others. On macOS, the equivalent shortcut is Cmd+Z, since the Mac uses the Command key rather than the Control key; German-language documentation may still refer to Strg in instructions on those systems. Some apps allow configurable shortcuts; some actions, such as deleting files or performing irreversible operations, may not be undoable depending on the context or application.

History and standardization: while the undo command has a long-standing presence in software design, there is no universal standard for its keyboard shortcut across platforms and programs. StrgZ is therefore a localized label for the broader undo concept rather than a distinct, universally standardized command.
