Q. Someone revised my presentation. Is there a way I can see exactly what they changed on each slide?
A. The Compare function in PowerPoint allows you to see how two presentations differ. With your version of the file open, on the Review tab, Compare group, choose Compare. It will ask you to choose a file to merge it. This is a bit of a misnomer, as nothing will merge until you say so. Select the changed file (the other person’s version) and click the Merge button.
You will now be able to see all of the changes noted both on the slide and in the Revisions task pane on the right. Just like in Word, you can choose to accept or reject changes, then save your new file, essentially merging the two documents with the changes you accepted.
