Actually, there were three :-) I forgot to mention that moving backwards in 
the slide show mostly works.  In particular, m.command handles undo 
correctly.  However, if you put your own "raw" code in a node, you must 
handle undo yourself.  This includes calls such as p.insertAfter.  Usually 
commander methods such as c.insertHeadline handle undo already.  When in 
doubt, look at the code.

Ideally, moving back one node should put up any captions, but it doesn't at 
present.  The workaround is to move back two nodes, then move forward a 
node.
