Editing a File
Editing a File
Creating Automatic Backup Files
You can reverse your last edit action by
choosing Edit 
Undo from the VLISP menu bar. You can undo
a virtually unlimited number of changes, back to the point at which
you last saved the file.
To reverse the effects of the Undo command,
choose Edit Redo from the menu. Redo only works if you
issue it immediately after Undo.
