There is support for (potentially unlimited) undo. However, there are 
many actions that are possible that have no undo yet.

You can undo things like move and delete, as I recall. Actually, 
here's the list of direct manipulation commands that can be undone:

Border width change
color change
set background to a picture
resize from halo
rotate from halo
move morph
change text morph margins
