Undo


Applied Parameters: None

Summary

This feature is used to restore the active Layer Stack to its state previous to the last operation. Multiple levels of undo are supported.

Access

This command can be accessed from the Layer Stack by:

  • Choosing the Edit » Undo command from the main menus.
  • Clicking the  button on the Quick Access bar.
  • Using the Ctrl+Z keyboard shortcut.
The command only becomes available provided a change to the Layer Stack has been made.
Use

After launching the command, the last operation will be 'undone' and the Layer Stack will be returned to its previous state. Use the command repeatedly to undo previous operations.

Tips

  1. A command that has been 'undone' using this command can be 'redone' using the Redo command.
