I have a naive idea that it might be possible to save NSUndoManager object's contents itself instead tracing document's changes separately with NSUndoManager. but NSUndoManager doesn't seem to allow access to contents of its instance. Would this be possible? how if so?

Have you tried just serializing the NSUndoManager with -encodeWithCoder:? I haven't tried it, but it seems to me that an undo managers should be archivable just like any other Appkit object.

Yes I have, John. but I doesn't seem to conform NSCoding protocol.

[NSArchiver archiveRootObject:myundos toFile:@"myundos.dat"];
-[NSUndoManager encodeWithCoder:]: selector not recognized.

Maybe I was too excited about undo manager? <grin>
Tyvm,
