CE Tool Bar - Undo and Redo
These buttons work exactly the way you expect them to work, but it is important to mention that the "Curve Editor’s" “Undo/Redo” is just a proxy of RealFlow’s global function. So if you clear the undo stack, this action also affects the "Curve Editor".
Undo
Undo last actions by clicking onto this button as often as required.
Redo
To restore the last actions, you can also click on this icon multiple times.
