With a PowerPoint document open, tap anywhere on the screen to bring up the top toolbar. Select the pencil icon in the top right corner to change to edit mode. Once in edit mode, you could select text in the slide to make changes.
A number of options are available to manipulate a PowerPoint document. To make quick edits, select text for formatting, and then tap the bold, italics or underline options found at the bottom of the screen. Paragraph formatting can also be done easily from this screen.
