This is how to do Alt + H + Q on Mac in PowerPoint with Accelerator Keys, the native ribbon and alt key shortcut solution for Mac users who get more done with PowerPoint.

Use this when you’ve moved or resized placeholders and want to return them to their original positions without losing the content inside them.
