The Undo command in the Main Window allows you to discard changes brought on by recent commands or drag/drop editing. Virtually all commands in the program can be undone, except for these few exceptions:
•File | Open, File | Close and File | Save As commands.
•File | Read Change File command.
•File | Merge File
•Network | Boundary Equivalent command.
•Options you entered in the File | Preferences command.
•Changing the “Type” of a distance relay.
TO UNDO A COMMAND:
1. Select the Tools | Undo ‘command_name’.
Note: The actual label of this menu will show the name of the command to be undone.
Shortcut: Press <Ctrl>+Z
The network and one-line diagram will be brought back to the state that existed prior to the command being undone. At any time, you can undo up to the last 8 commands.
