Ghost hints

possible error in the Manual and Tutorial on adding ghost hints:

I can only turn a horizontal hint to a ghost hint if it has been created by selecting TWO nodes, not one.

Is this correct?

I was trying to add ghost hints to a rounded terminal font where there is only a singe extrema node, but could not do that.

CREATING a ghost hint:
You select one node that touches a zone, then right click, and pick Add Ghost Hint from the context menu.

CONVERTING to a ghost hint:
You can convert an existing horizontal stem hint to a ghost hint if you select the hint (click on the number badge), then invoke the context menu, and pick Make Ghost Hint.

yes, that what I read a few times, however I was only able to get “Add Ghost Hint” available when doing the selection I’ve described.

Also, are Family zones implemented?
