Thanks for the insight - being new to DT its hard to figure out what of the online help articles are current.
Re: Data > Move To… command,
are you talking about the window that pops up when I hit that? Unless I’m missing something that still doesn’t give me a quick keyboard shortcut to move the item to my desired folder…
Seems like this should be a simple thing to do 
Re: trying See Also & Classify inspector, that sometimes does show the desired target group, but not always. (If I try the Classify toolbar button, usually it is not showing any Group name and only generates an error in the Log.) Is there some way to “advise” the AI as to what choices are best? But even if it put my desired Group at the top of the list there’s no apparent keyboard shortcut for it.
