There are many ways to do the same task in PowerPoint, and all Microsoft Office applications. Rotating objects is one that many find difficult and tedious when using the rotate anchor. Using keyboard shortcuts to rotate an object (or several objects at the same time) is an amazing shortcut to know about!
Select any shape
Use the keyboard to rotate the shape to the right with ALT + RIGHT ARROW. Hold the ALT key down and click the right arrow as many times as needed to get the rotation desired.
This is pretty much intuitive at this point, but ALT + LEFT ARROW will rotate the selected object(s) to the left. To go from the above rotation to the below rotation it was hold the ALT key and click the left arrow twice
Happy rotating!
