How to Replace Text in a PowerPoint 2013 Presentation
Repeat the Find Next and Replace sequence until you’re finished.
Click Find Next to find the next occurrence, click Replace to replace it, and so on. Keep going until you finish.
If you’re absolutely positive that you want to replace all occurrences of your Find What text with the Replace With text, click the Replace All button. This step dispenses with the Find Next and Replace cycle.
The only problem is that you’re bound to find at least one spot where you didn’t want the replacement to occur. Replacing the word mitt with glove, for example, results in Sglovey rather than Smitty. Don’t forget that you can also use the Find Whole Words Only option to find and replace text only if it appears as an entire word.
