For example, Ctrl keyboard shortcuts become Cmd keyboard shortcuts on the Mac, even though Macs have the Ctrl key.

Yes, people do try the same shortcuts on both operating systems, but they don’t work that way most of the time. There may be any number of other reasons for the keyboard shortcut not working. No, there's nothing wrong with the keyboard shortcut you pressed, or even with PowerPoint.

It's so awesome that PowerPoint and other Microsoft Office programs offer so many keyboard shortcuts, but has it ever happened that you press a keyboard shortcut in PowerPoint, and it does not work?
