How do I add a context menu item?

The Edit Person Context menu has an option to make a Person the Active Record.

It would be make it MUCH easier to find a Family in the Families category if the Edit Family context menu had a “Make Family active”

And the Clipboard has a generic Make <object> Active context menu. (That doesn’t apply to Ref Object, unfortunately.)

It doesn’t look like the Object Editor use a common Context menu subroutine? The Event, Place, Source, Citation, Repository, Media and Note Object Editors don’t have a Context Menu at all. Why not?

Hmmm… I’ve tried to get this info repeatedly
