I was trying to edit a slide, and wanted to delete and add some important pieces of text. Instead, of completely deleting the text — I wanted to make it strikethrough so that the audience knows what has changed. Here’s what Powerpoint suggests:
Microsoft Office PowerPoint does not include the text effects for strikethrough on the Format menu that come with Microsoft Office Word. You can reproduce these effects by using the Drawing toolbar, however.
1. Display the slide with the text you want to show in strikethrough format.
2. From the Drawing toolbar in the lower-left corner of the screen, choose the Line tool.
3. Draw a line over the text you want to format as strikethrough.
Lame, lame, lame, lame!
