You can put a hidden, unsaved (if you want) "key" field
inside the Concept - Concept object. When you click on "View", you fetch the
value of this key property, populate dialog1 and display it. When the user
clicks "OK", you change the "key" property on the object's copy supplied to
your "View" event, and the StdProp library will propagate it to the object
if the user clicks on "apply" or "OK", and push the former value on the undo
stack as well.

You may even want to not hide this key value from the main property dialog.
I don't know why you don't want to save it. I don't remember for sure, but
there may be a "PROP_FLAG_READ_ONLY" if you want that the only way to change
the key is through your UI.

Hmmm. You can have several keys. Uh oh. Either your main key field is a
$SEPARATOR-separated list string, or I'd better start working on
PROP_TYPE_LIST...
