The Undo Manager adds 32 levels of Undo and Redo to your LineEdit, TextEdit, or Picture controls. To activate Undo and Redo Menu Items, simply install the Undo Manager, add Redo to your Edit Menu, and add a few simple commands to your application code.
Up to 8 applications can between them control up to 32 controls at any one time, and each control will have 32 levels of Undo and Redo.

Coding examples for many different platforms are provided.
