Undo and Redo

Undo and Redo allow operations on slides in a slide show to be redone if desired.

Undo will restore the slide show to its organization before the last operation.  Redo cancels the action of the previous Undo and restores the changes.

The functions effect the results of Copy, Paste, Cut and Delete

Both functions may be executed repeatedly so that the entire editing history of a slide show may be revisited and restored. 

Short cut keys:

Undo:   Ctrl+Z
Redo:    Ctrl+Y
