Deleting slides
By default, the maximum number of Undo operations is 20, but you can change this. Choose File
Options, then
click Advanced, and in the Editing options section, change the Maximum number of undos setting. Keep in mind that
if you set the number of undos too high, it can cause performance problems in PowerPoint.
You can undo multiple actions at once by opening the Undo button’s drop-down list, as shown
in Figure 21.25. Just drag the mouse across the actions that you want to undo (you don’t need
to hold down the mouse button). Click when the desired actions are selected, and presto, they
are all reversed. You can select multiple actions to undo, but you can’t skip around. For
example, to undo the fourth item, you must undo the fi rst, second, and third ones, as well.
FIGURE 21.25
Use the Undo button to undo your mistakes and the Redo button to reverse an Undo
The Redo command is the opposite of Undo. If you make a mistake with the Undo button,
you can fi x the problem by clicking the Redo button. Like the Undo button, it has a
dropdown list, and so you can redo multiple actions at once.
The Redo command is available only immediately after you use the Undo command. If Redo
isn’t available, a Repeat button appears in its place. The Repeat command enables you to repeat
the last action that you performed (and it doesn’t have to be an Undo operation). For example,
you can repeat some typing, or some formatting. Figure 21.26 shows the Repeat button.

The Repeat button appears when Redo is not available, and enables you to repeat actions.
