Mark the Limit undo/redo to check box, and type or set a value in the control.
The default is 250.
Make the redo process faster
Mark the Enable fast redo check box. This may slightly slow down the undo process, so if you rarely perform a redo, but use undo frequently, you may want to unmark this check box.

Type or set a value in the Non-undoable steps in History Palette control.
