Peter, thanks for the response and for letting the "secret" out!
However, the RealTracks data that is placed on the clipboard does not include the Instrument, Type, Feel, Tempo or Genre columns, which, at least for my purposes, diminishes the usefulness of the "feature". Like many users, I do not use styles at all, but instead assemble a combo or band for a particular tune by picking from the individual RealTracks, using parameters like tempo, feel, instrument, genre or artist. Even though the RealTracks picker dialog can be filtered and sorted by a given column, it still cannot be analyzed in the same complex way that a spreadsheet program like Excel would allow. The RealTracks library is so large (and this is a really GOOD thing), that the ability to analyze it and select a particular track or group of tracks can be very time consuming, and I feel that employing a spreadsheet program as an aide to that process would be very useful.
