checl "recentNames" in the dictionary, that may be what you are looking for.

Yep.

Then the card will receive a "resumestack" (and "suspendstack"), but no "opencard" message.

> I’m not sure I understand the full range of events that “close” a card so that returning to it triggers “openCard.”  Does this happen if I set an insertion point or select text in an unlocked field in a palette, or the user types there?  Does it happen if I open a palette, or move a palette, or if the user clicks on the palette?

See above, resumestack/suspendstack are the messages you could check, if neccessary, in that case.
