Show Camera command to show widget and FOV

Is the “Show Camera” command implemented in the Mac version. I am trying to show the camera widget as shown in the following Rhino 5 help page:

When I set a camera and target and then zoom out and issue the Show Camera command, the message area at the bottom of the Rhino window says that the “Camera object is visible,” but I don’t see anything.

What am I doing wrong?

ShowCamera and HideCamera are just built-in aliases for the “real” command:

_Camera ( Show Hide Toggle )

The camera will not be shown in the active viewport (active at the time the command is run), only in the others.
