Hi Stephane,

If what you mean is you don't want a particular morph to have halos =
when cmd-clicked, then implement

^ false

for that morph, but be careful as that may make it harder to debug or =
delete that morph.

The symmetry is missing, I suppose, because #delete works in all cases =
to break the owner<->submorph relationship. Adding something to the =
world, on the other hand, has a huge number of possibilities: which =
existing morph you wish to be the owner of the new morph and where =
(first, last, other..) the new morph should be positioned relative to =
any existing submorphs of the new owner.

>Question 5 Is caseOf: really used?

It doesn't appear to be used in the image, but perhaps some folks use =
it in private fileins.

Update: As of 3.1alpha, it seems to be used in a few methods, but you have to find it by searching source, since it's inlined and a standard "senders of..." search won't find it. - RandalSchwartz
