[MlMt] folder based on colored flags?

[Steven M. Bellovin]

It was good to learn that F+<0-7> could be used for different-colored 
flags.  Is there some keyword or tag that I can query associated with 
this?  I'd like to be able to flag messages for different purposes and 
then have subfolders of "Flagged" for different colors/purposes.
