    \playMark ?

Do you think we could adequately capture the semantics of all three kinds of 
marks in a single \playMark command?  How would you identify if a given 
\playMark command establish a jump-from, jump-to, or stop point?

By having different commands I intended we would have different events, which 
could respond appropriately with iterators when doing unfolded playback.  If 
there's another way to do that, I'd be happy to have a single command, but I 
think I prefer \flowMark to \playMark, because it is more specific about the 
intent of the mark.

Thanks,
