A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Objects, yes, Text, no. Text Boxes, Placeholders or other Shapes containing text would have to be Cut then pasted back in using Edit> Paste Special, PDF or Picture. You can then use the Rotate menu button in the Size, Rotation and Ordering group on the Formatting Palette of the Toolbox to Flip Horizontal.
If this is strictly for print purposes, though, you needn't go to all that trouble. Print only the slide you want reversed but in the Print dialog open the Copies & Pages menu, select Layout & check the box for Flip Horizontally.
